The 1z0-531 Exam is designed for implementation specialists who have a strong foundational knowledge of building and managing Oracle Essbase 11 applications. This certification, Oracle Essbase 11 Certified Implementation Specialist, validates a candidate's ability to design, build, and maintain Essbase cubes. It signifies proficiency in core areas such as application design, dimension building, data loading, calculation scripting, and security configuration. The exam is targeted at technical consultants, developers, and administrators who are responsible for implementing robust analytical and business intelligence solutions using the Essbase platform.
Successfully passing the 1z0-531 Exam demonstrates a comprehensive understanding of both Block Storage (BSO) and Aggregate Storage (ASO) database options. Candidates are expected to know the appropriate use cases for each storage type and how to leverage their unique features. The exam covers the entire lifecycle of an Essbase implementation, from initial requirements gathering and design to deployment and ongoing maintenance. Achieving this certification serves as a formal recognition of your expertise and can significantly enhance your professional credibility within the Oracle EPM and BI community, showing you have mastered the skills needed for this powerful tool.
Before diving into the specifics of the 1z0-531 Exam, it is crucial to understand the technology that Essbase is built upon: Online Analytical Processing, or OLAP. OLAP databases are designed for rapid, complex data analysis, contrasting with Online Transaction Processing (OLTP) systems that are optimized for managing transactional data. Essbase is a multidimensional OLAP server, which means it stores data in a structure known as a cube. This cube is not a literal geometric shape but a conceptual model where data is organized and stored by multiple business dimensions, such as Time, Product, Geography, and Scenario.
Each dimension in an Essbase cube contains a hierarchy of members. For instance, the Geography dimension might have members for countries, which contain members for states or provinces, which in turn contain cities. The intersection of one member from each dimension defines a unique data cell where a numeric value, like sales or units, is stored. This multidimensional structure allows users to "slice and dice" the data, for example, viewing sales for a specific product in a particular city during a certain month. This ability to perform complex analysis from various perspectives is the core strength of Essbase.
A key area of focus for the 1z0-531 Exam is the Essbase architecture. The system operates on a client-server model. At its heart is the Essbase Server, which is the engine responsible for managing the multidimensional databases (cubes), processing calculations, and handling user queries. The server manages all the data and metadata files that constitute the Essbase applications. Understanding how the server processes requests and manages memory is important for tuning and optimization, which are advanced topics covered in the exam syllabus.
Users and administrators interact with the Essbase Server through various client tools. The primary administrative tool is the Essbase Administration Services (EAS) Console. This is a graphical interface used to create, manage, and secure Essbase applications. Other client tools include Oracle Smart View for Office, which is an add-in for Microsoft Excel, Word, and PowerPoint that allows users to perform ad-hoc analysis, build reports, and submit data. The architecture also includes a layer for user authentication and provisioning, typically managed through Oracle Shared Services.
One of the most fundamental concepts tested in the 1z0-531 Exam is the difference between the two database storage options: Block Storage Option (BSO) and Aggregate Storage Option (ASO). BSO is the classic Essbase storage model and is optimized for applications that require complex, procedural calculations and frequent data input. In a BSO cube, data is stored in physical "blocks," which are defined by the combinations of sparse dimension members. This block-based structure is highly efficient for running detailed business logic written in Essbase's calculation script language.
Aggregate Storage Option (ASO), on the other hand, is designed for applications with very large dimensions and a primary focus on fast data aggregation and reporting. ASO cubes do not use calculation scripts in the same way BSO cubes do. Instead, they aggregate data on the fly using a highly optimized aggregation engine. ASO is ideal for large-scale reporting cubes where the main requirement is to query vast amounts of data with minimal response time. Choosing the correct storage option is a critical design decision, and the 1z0-531 Exam will test your ability to make this choice based on specific business requirements.
BSO applications are often used for detailed budgeting, planning, and forecasting, where users input data and run rules to calculate things like driver-based expenses or allocations. They support a write-back capability, making them interactive. In contrast, ASO applications are typically read-only from an end-user perspective and are often sourced from a data warehouse or a BSO cube. A common architecture involves a BSO cube for calculations, which then pushes the results to a larger ASO cube for reporting and analysis by a wider audience.
The structure of any Essbase cube is defined by its dimensions, and a deep understanding of them is required for the 1z0-531 Exam. Dimensions provide the business context for the numeric data. An Essbase application consists of an outline file that contains all the dimensions and their members. Common standard dimensions include Time, Accounts, and Entity, but most applications will also have several custom dimensions like Product, Customer, or Department to reflect the specific needs of the business.
Each dimension is composed of members organized into one or more hierarchies. These hierarchies represent the relationships between the members, typically in a parent-child structure. For example, a "Total Year" member might be the parent of four "Quarter" members (Q1, Q2, Q3, Q4), and each quarter would be the parent of three "Month" members. This hierarchical structure is what enables data aggregation, or "roll-ups," as well as the ability for users to "drill down" from a summary level to a more detailed level of data.
Hierarchies are further defined by levels and generations. A generation is a member's distance from the dimension's root, while a level represents a member's distance from the bottom of a hierarchy branch. These concepts are important for writing calculation scripts and for designing reports. Members also have various properties that define their behavior, such as consolidation operators that determine whether a child's value should be added, subtracted, or ignored when rolling up to its parent.
A critical design concept for BSO cubes, and a major topic on the 1z0-531 Exam, is the distinction between dense and sparse dimensions. This setting determines how Essbase stores data in the underlying data blocks and has a massive impact on performance and database size. In a BSO cube, every possible combination of members from the dense dimensions exists within each data block. Therefore, the dimensions you designate as dense should be those for which you expect a high probability of data existing for most combinations of members.
Sparse dimensions, conversely, are used to define the data blocks themselves. A data block is only created if at least one data value exists for a specific combination of sparse dimension members. This mechanism prevents Essbase from having to store a massive amount of empty, or #MISSING, data for combinations that do not exist in the real world. For example, it is unlikely that every product is sold in every single store. Therefore, Product and Store would typically be set as sparse dimensions.
The classic example of dense dimensions is Period and Accounts. It is highly likely that for a given entity and product (the sparse combination that defines the block), you will have data for most accounts (like Sales, COGS, Margin) and for most months of the year. Making these dimensions dense ensures that the data block is efficiently structured and reduces the database size. Making the correct dense/sparse choice is one of the most important skills for an Essbase developer, as a poor design can lead to severe performance issues.
The Essbase Administration Services (EAS) Console is the primary tool for developing and managing Essbase applications. A significant portion of the 1z0-531 Exam will test your ability to perform tasks within this interface. The EAS Console is a Java-based client that connects to the Essbase server and provides a graphical environment for most administrative and development activities. When you first log in, you are presented with the Enterprise View, which shows a tree structure of all the available Essbase servers and the applications they contain.
From the Enterprise View, you can perform a wide range of actions. You can create new applications and databases, start and stop them, and manage their properties. The most common activity for a developer is editing the database outline. Right-clicking on a database and selecting "Edit Outline" opens the outline editor, where you build and modify your dimensions, members, and hierarchies. The EAS Console also provides interfaces for creating and managing calculation scripts, data load rules, security filters, and more.
Beyond development, the EAS Console is used for ongoing administration. You can monitor active user sessions, view server and application logs to troubleshoot issues, and manage application backups. You can also view statistics about your databases, such as the number of data blocks and the database size, which is useful for performance tuning. Familiarity with the layout and functionality of the EAS Console is absolutely essential for anyone preparing for the 1z0-531 Exam.
The 1z0-531 Exam expects you to know the practical steps involved in creating a new Essbase solution from scratch. The process begins in the EAS Console. The first step is to create an application, which acts as a container for one or more databases. To do this, you right-click on an Essbase server in the Enterprise View and select "Create Application." You will be prompted to provide a name for the application. The application itself does not hold data but provides a logical grouping for its databases.
Once the application is created, the next step is to create a database within it. You right-click on the new application and select "Create Database." This is where you make one of the most critical decisions: the database type. You must choose between Block Storage (BSO) and Aggregate Storage (ASO). This choice is determined by the business requirements and cannot be easily changed later. After selecting the type and giving the database a name, Essbase creates the shell of the database, including the necessary file and folder structure on the server.
After the database is created, it is initially empty. It has no dimensions and no data. The next phase of development involves building the database outline, which is the metadata structure that defines the dimensions and members. This can be done manually in the outline editor or, more commonly, by loading a metadata build file using a rules file. This foundational process of creating the application and database is a prerequisite for all other development activities and a core competency for any Essbase specialist.
While it is possible to build an Essbase outline manually in the EAS Console, this is impractical for all but the smallest dimensions. The standard and most efficient method, and a key topic for the 1z0-531 Exam, is to use a dimension build rules file. A rules file is an object created in EAS that defines how to interpret a source data file (typically a text file) and use it to build or modify a dimension hierarchy. This allows for the automated and repeatable construction of large and complex dimensions from a source system like an ERP or a data warehouse.
A rules file works by mapping the columns, or fields, from the source file to different properties of a dimension member. For example, one column might contain the child member's name, while another column contains its parent's name. The rules file specifies which field is the child, which is the parent, and how to establish the relationship between them. You can also map fields to other properties like aliases, formulas, or consolidation operators. The rules file provides a flexible and powerful way to translate a flat source file into a hierarchical structure.
The dimension build process is highly configurable. The rules file contains settings that control how the build is performed. You can specify whether you are building a new dimension from scratch or modifying an existing one. You can define sorting options to ensure the hierarchy is built correctly and control how the rules file handles new or changed records. Mastering the creation and execution of dimension build rules files is a fundamental skill for any Essbase developer and is heavily tested in the 1z0-531 Exam.
Beyond the basic parent-child structure, Essbase members have several advanced properties that control their behavior. Understanding these properties is crucial for the 1z0-531 Exam. One of the most important is the data storage property for BSO cubes. This property determines how a member's data is stored and calculated. For example, "Store" means the data is physically stored in the database. "Never Share" is similar but prevents the value from being consolidated to its parent. "Dynamic Calc" means the member's value is not stored but is calculated on-the-fly when it is requested by a user.
Consolidation operators are another key property. By default, child members are added (+) to their parent during a database aggregation. However, you can change this operator to subtract (-), multiply (*), divide (/), or even ignore (~) the child's value in the parent's consolidation. This is commonly used in an accounts dimension, where expense accounts are subtracted from revenue accounts to calculate profit. Aliases provide alternative names for members, which is useful for creating more user-friendly reports or supporting multiple languages.
Attribute dimensions provide another way to classify and analyze data without adding more sparse dimensions to your main cube structure. An attribute dimension is associated with a primary, or base, dimension. For example, you could associate attributes like "Size" and "Color" with a "Product" dimension. This allows users to analyze data by these attributes (e.g., show sales for all large, red products) without the performance overhead of making Size and Color their own sparse dimensions.
Once your dimensions are built, the next step is to load data into the cube. The process for loading data is very similar to building dimensions; it uses a source data file and a data load rules file. The rules file maps the columns in the source file to the dimensions in your Essbase cube, and it identifies which column contains the data value to be loaded. The source file must contain one record for each data point, with each record specifying the member from each dimension that defines the data cell's location.
The data load rules file has several options to control how the data is loaded. You can specify whether the new data values should be added to, subtracted from, or overwrite the existing values in the database. This is important for managing different types of data loads, such as loading monthly actuals versus loading budget adjustments. You can also define data validation rules within the rules file to reject records that contain invalid data.
Data loading specifics can differ between BSO and ASO cubes. For BSO cubes, data is loaded into the input-level (level 0) blocks, and then a calculation is typically run to aggregate the data up the hierarchies. For ASO cubes, the data is loaded into a data staging area, and then the aggregations are built as part of the data load process itself. The 1z0-531 Exam will expect you to understand the mechanics of data loading for both cube types.
A successful Essbase implementation requires robust and reliable data loading processes. The data load settings within a rules file provide fine-grained control over this process. One of the most important settings is the ability to clear data before a load. If you are loading a complete data set for a particular scenario and period, you will often want to clear any pre-existing data for that slice to avoid double-counting. A rules file can be configured to clear specific regions of the database before it proceeds with the load.
Error handling is another critical aspect. When a data load process runs, Essbase can generate an error log file. This log will capture any records from the source file that were rejected and provide a reason for the rejection. Common reasons include a member not being found in the outline or a data value being non-numeric. An administrator must know how to locate and interpret this error log to troubleshoot and correct any issues with the source data or the rules file.
For very large data loads, performance can be a consideration. The rules file and the underlying database can be tuned for optimal load performance. This can include things like pre-sorting the data source file to match the order of the dimensions in the outline or adjusting cache settings on the Essbase server. While deep performance tuning is an advanced topic, the 1z0-531 Exam will expect you to be familiar with the basic settings and best practices for efficient data loading.
Variables in Essbase are powerful tools that provide flexibility and dynamic capabilities to your application. The 1z0-531 Exam requires you to know the difference between the two main types: substitution variables and user variables. Substitution variables are global placeholders that have a single value across the entire application or server. They are set by an administrator and are commonly used to represent information that changes periodically, such as the current month or current year.
For example, you could create a substitution variable named "CurMnth" and set its value to "Jan." You can then reference this variable in reports, calculation scripts, and data load rules. A report designed to show data for the "current month" can reference &CurMnth. When the month changes to February, the administrator only needs to update the variable's value in one place, and all the reports and scripts that reference it will automatically update. This makes the application much easier to maintain.
User variables, on the other hand, have values that are specific to each individual user. Each user can set their own value for a user variable. This is often used to customize the user experience. For example, you could have a user variable called "MyRegion." A user in North America could set their value to "NA," while a user in Europe could set it to "EU." A generic report could then be designed to show data for the region specified in the "MyRegion" user variable, allowing a single report to serve multiple users with personalized views.
The database outline is the metadata blueprint of your Essbase application. Managing this outline effectively is key to a healthy and high-performing application. The order of the dimensions in the outline can have an impact on performance, especially for BSO cubes. As a general best practice, dimensions should be ordered from the smallest and least frequently changing (like Time) to the largest and most frequently changing (like Entity or Product).
The outline is also where you define the dense and sparse settings for a BSO cube. As discussed earlier, this is a critical design decision. The outline editor in EAS allows you to change these settings, but doing so often requires a full restructure of the database, which can be a time-consuming process. Therefore, it is important to get the dense/sparse design right from the beginning. A good design will result in a smaller database size and faster calculations and retrievals.
Over time, as business needs change, you may need to make significant changes to the outline, such as adding new members or entire dimensions. When this happens, Essbase will need to restructure the database. There are two types of restructures: dense and sparse. A dense restructure (caused by changes to dense dimensions) is generally faster than a sparse restructure. The 1z0-531 Exam will expect you to understand the implications of making changes to the outline and the different types of restructures.
After every data load, it is crucial to perform validation and reconciliation to ensure the data in the Essbase cube is accurate and matches the source system. The first step is often a high-level check to ensure the total values match. For example, you can run a query in Essbase to get the total sales for the entire company and compare that to the total sales figure from the source data file or ERP system. Any significant discrepancies would indicate a problem with the data load process.
Smart View is an invaluable tool for data validation. An analyst can quickly create an ad-hoc grid in Excel to pull data from the cube and compare it side-by-side with data from the source system. The ability to pivot and drill down allows for a detailed investigation into any variances that are found. For example, if the total company sales match but the sales for a specific region are off, the analyst can drill down into the products and customers within that region to pinpoint the exact source of the discrepancy.
Another validation step is to check that the data is aggregating correctly up the hierarchies. You can enter or load data at a low level in a hierarchy and then retrieve the value for its parent to ensure the consolidation logic is working as expected. For BSO cubes, this confirms that your aggregation scripts are correct. For ASO cubes, it validates the hierarchy definitions. A rigorous data validation process is essential for building user trust in the system, a key goal of any implementation.
For Block Storage Option (BSO) databases, calculation scripts are the primary mechanism for performing calculations, aggregations, and implementing business logic. An understanding of how to write and manage these scripts is at the heart of the 1z0-531 Exam. A calculation script is a text file containing a series of commands that instruct the Essbase calculation engine on how to manipulate the data in the cube. These scripts are created and managed within the Essbase Administration Services (EAS) Console.
The most common use of a calculation script is to aggregate the data up the dimension hierarchies. While Essbase can aggregate data based on simple consolidation properties in the outline, most real-world applications require more complex logic that can only be handled by a calculation script. For example, a script can perform allocations, currency conversions, driver-based calculations, and conditional logic. These scripts can be launched manually by a user or an administrator, or they can be scheduled to run as part of an automated batch process.
Calculation scripts operate on the data stored in the database. When a script is executed, the Essbase server reads the commands, retrieves the necessary data blocks from the database, performs the specified calculations, and then writes the results back to the database. The efficiency of this process is highly dependent on how well the script is written. A poorly written script can take hours to run and negatively impact the performance of the entire application.
To pass the 1z0-531 Exam, you must be comfortable with the basic syntax of the Essbase calculation script language. The language is procedural and consists of commands, formulas, and functions. A typical script is composed of one or more calculation blocks. A simple formula might look like "Margin" = "Sales" - "COGS";. This command calculates the value for the "Margin" member by subtracting the value of the "Cost of Goods Sold" member from the "Sales" member. Every command in a calculation script must end with a semicolon.
The calculation engine processes the outline and the data in a specific order, which is known as the calculation order. By default, Essbase calculates dense dimensions first, followed by sparse dimensions. Understanding this order is crucial for writing accurate calculations, especially when a formula depends on values that are themselves calculated. The concept of calculation passes is also important. Some complex formulas may require the database to be calculated multiple times to arrive at the correct result.
You can also embed formulas directly onto members in the database outline. These are known as member formulas. When a member with a formula is calculated, Essbase executes the associated formula. While this can be convenient for simple calculations, it is a best practice to keep most of the complex business logic within calculation scripts. This makes the logic easier to manage, debug, and maintain, as it is all located in a central place rather than being scattered throughout the outline.
The single most important command for writing efficient and effective calculation scripts is FIX...ENDFIX. This command is heavily tested on the 1z0-531 Exam because it is fundamental to performance. The FIX command allows you to temporarily limit, or "fix," the scope of the calculation to a specific slice of the database. Any calculation commands placed between the FIX and ENDFIX statements will only be executed for the data cells that fall within the specified dimensional intersection.
For example, if you only want to run a calculation on the "Budget" scenario for the "New York" entity, you would enclose your formulas within a FIX("Budget", "New York") block. This prevents the Essbase engine from wasting time and resources by looping through all the other scenarios and entities, such as "Actuals" or "California." By dramatically reducing the number of data blocks that the calculation needs to consider, the FIX command can improve performance by orders of magnitude.
You can fix on multiple members from different dimensions, and you can even use functions within the FIX statement to dynamically select the members. For example, FIX(@CHILDREN("East")) would limit the calculation to only the direct children of the "East" member in the geography dimension. It is a critical best practice to always enclose your calculations within the tightest possible FIX statement to ensure that you are only calculating the data that needs to be calculated.
The Essbase calculation script language includes a rich library of over a hundred built-in functions that allow you to perform a wide range of analytical and business calculations. The 1z0-531 Exam will expect you to be familiar with the most common ones. Mathematical functions like @SUM, @SUMRANGE, @AVG, and @COUNT are used to perform aggregations and statistical calculations. For example, @SUMRANGE("Sales", @CHILDREN("Product")) would sum the sales for all the children of the "Product" member.
Relationship functions allow you to navigate the dimension hierarchies within your script. Functions like @PARENT, @CHILDREN, @ANCESTORS, and @DESCENDANTS are used to select members based on their relationship to another member. These are extremely useful for writing dynamic calculations that are not dependent on a hardcoded hierarchy. For example, you can write a rule that allocates a parent entity's corporate overhead to all of its descendants, regardless of how many levels of descendants there are.
There are also several SET commands that can be used at the beginning of a script to control the behavior of the calculation engine. For example, SET CALCPARALLEL can be used to enable parallel calculation on servers with multiple processors. SET AGGMISSG ON/OFF controls whether Essbase consolidates #MISSING values. SET CREATEBLOCKONEQ ON/OFF controls when Essbase creates new data blocks during a calculation. Knowing how and when to use these commands is key to optimizing your scripts.
When designing a BSO cube, you have a choice for each member: you can either store its calculated value in the database or calculate it dynamically when a user retrieves the data. This is controlled by the member's data storage property. Members that are tagged as "Dynamic Calc" do not have their values stored on disk. Instead, their values are computed in memory when a user runs a report or a query that includes them. This is a crucial concept for the 1z0-531 Exam.
The main advantage of using dynamic calculations is that it reduces the size of the database and can significantly speed up your batch calculation scripts. Since the values are not stored, you do not need to run a script to calculate them, and they do not take up any space on the disk. This is ideal for members that are simple ratios or sums and for members at the upper levels of large, sparse dimensions, where storing the aggregated values would create a massive number of data blocks.
However, there is a trade-off. While dynamic calculations speed up your batch script, they can slow down data retrieval times for the users. This is because the calculation has to be performed in real-time during the query. The key is to find the right balance. A common best practice is to use dynamic calculations for simple ratios and upper-level members of sparse dimensions, while continuing to store the results of complex, multi-step calculations that would be too slow to perform on the fly.
Some business calculations are complex and cannot be solved in a single pass through the database. A classic example is calculating a member as a percentage of its parent. For example, you might want to calculate each product's sales as a percentage of the total product sales. To do this, Essbase first needs to calculate the total product sales by summing up all the individual products. Only then, in a second pass, can it come back and calculate the percentage for each individual product.
Essbase handles this by allowing you to tag members as "Two-Pass." When a member is tagged as two-pass, any formula on that member will be calculated after the main database calculation has finished aggregating the dimensions. This ensures that all the necessary components of the formula have been calculated before the formula itself is executed. This is a specific but important feature that you may be asked about on the 1z0-531 Exam.
You can also perform calculations based on attribute dimensions. The calculation script language includes functions that allow you to sum or average data for all the base members that share a common attribute. For example, you could calculate the average sales for all products that have the attribute "Large." This provides a powerful way to perform analysis across different slices of your data without having to build complex logic that references individual members.
Calculation script performance is a critical topic for any Essbase implementation specialist. A slow-running script can delay reporting cycles and frustrate users. The single most important optimization technique is the effective use of the FIX...ENDFIX command to limit the scope of the calculation. Beyond that, there are several other best practices that are relevant for the 1z0-531 Exam. The order of the dimensions in your FIX statements matters. It is generally more efficient to fix on sparse dimension members before fixing on dense dimension members.
Understanding block creation is also key. Essbase only creates a data block when a value is loaded or calculated for a unique combination of sparse dimension members. You can control this behavior with the SET CREATEBLOCKONEQ ON; command, which tells Essbase to only create a block if the result of a formula is not #MISSING. This can prevent your database from becoming bloated with millions of empty blocks, which would slow down all subsequent calculations and queries.
The physical design of the cube also has a huge impact. The choice of dense and sparse dimensions is the most critical factor. Calculations are generally much faster on dense dimensions since all the data is contained within a single block. Therefore, dimensions that are frequently used in complex calculations should be considered as candidates for being dense. Regularly monitoring calculation times and analyzing scripts for inefficiencies is a key part of maintaining a high-performing Essbase application.
Even experienced developers make mistakes when writing calculation scripts. Knowing how to debug and troubleshoot these scripts is an essential skill for the 1z0-531 Exam. The first place to look when a script fails is the application log file. The log will usually contain an error message that indicates the line number in the script where the error occurred and a description of the error, such as a syntax error or an invalid member name.
If a script runs without errors but produces incorrect results, the debugging process is more complex. A common technique is to use a "test" member in your outline. You can temporarily modify your script to write the intermediate results of a complex calculation to this test member. By retrieving the data from this member, you can see the values at each step of the calculation and pinpoint where the logic is going wrong. Once you have fixed the issue, you can remove the debugging code from your script.
Another useful strategy is to heavily use the FIX command to isolate the problem. If you suspect an issue with a specific entity or product, you can add a FIX statement to your script to run the calculation for only that single member. This allows you to focus your analysis on a very small slice of data, which makes it much easier to validate the results and find the source of the logical error. A systematic and patient approach is key to successful debugging.
While Part 3 focused on BSO calculations, the 1z0-531 Exam also requires a strong understanding of Aggregate Storage Option (ASO) cubes. As a refresher, ASO is designed for large-scale, read-only reporting applications. The design considerations for an ASO cube are different from those for a BSO cube. ASO cubes do not have the concept of dense and sparse dimensions. Instead, all dimensions behave like sparse dimensions in terms of data storage. ASO is optimized to handle dimensions with a very large number of members.
ASO outlines have some unique features. Hierarchies in ASO dimensions can be defined as "stored" or "dynamic." A stored hierarchy behaves like a traditional Essbase hierarchy, where the member relationships are fixed. A dynamic hierarchy, on the other hand, can be generated on-the-fly based on a parent-child relationship in a relational database table. This is useful for hierarchies that change frequently. ASO outlines also support multiple hierarchies within a single dimension, which allows users to view and analyze the data in different ways.
Building an ASO cube is typically a more automated process than building a BSO cube. The metadata and data for ASO cubes are almost always sourced from a relational data warehouse. The dimension build and data load processes are often managed through Essbase Studio or by loading data directly from relational tables. The focus is on efficiently getting large volumes of data into the cube so that it can be aggregated for reporting.
The key feature that makes ASO so fast for reporting is its aggregation engine. When you load data into an ASO cube, Essbase can pre-calculate and store aggregations of the data. For example, it can sum up all the city-level data to create state-level totals, and all the state-level data to create country-level totals. These pre-calculated results are stored in what are known as "aggregation views." When a user queries the database for a country-level total, Essbase can retrieve the pre-calculated value instantly, rather than having to sum up all the cities in real-time.
The process of designing which aggregations to store is critical to ASO performance. The Essbase server can automatically select which aggregations to build based on the structure of the outline and query tracking data. Alternatively, an administrator can manually define the aggregation views. The goal is to create aggregations for the most frequently queried data intersections to provide the best possible performance for the users. There is a trade-off, however, as each aggregation view takes up disk space and adds time to the data load process.
Finding the right balance is key. You want to build enough aggregations to satisfy the majority of your users' queries without making the database unnecessarily large or the data load process too long. The 1z0-531 Exam will expect you to understand the concept of ASO aggregations and their role in optimizing query performance. You should know that aggregations are the reason why ASO can handle much larger volumes of data than BSO.
ASO cubes do not use the traditional Essbase calculation script language for calculations. Instead, they use the Multidimensional Expressions (MDX) language. MDX is the industry standard query language for OLAP databases. While a full mastery of MDX is a subject in itself, the 1z0-531 Exam requires you to have a foundational understanding of its role in an ASO context. MDX is used for two primary purposes in ASO: defining member formulas and creating complex queries.
Member formulas in an ASO outline can be used to define dynamically calculated members. For example, you can create a new member called "Margin %" and write an MDX formula that defines it as ("Sales" / "COGS") * 100. This formula is executed in real-time when a user retrieves the "Margin %" member. This allows you to add calculations and ratios to your ASO cube without having to store the data, which is very similar to how "Dynamic Calc" members work in a BSO cube.
MDX is also used by reporting tools and advanced users to write custom queries against the ASO database. An MDX query can be used to select a very specific slice of data, perform calculations, and define the layout of the resulting grid. While tools like Smart View can generate MDX queries for you behind the scenes, an administrator who knows MDX can write highly optimized queries for specific reporting needs. For the exam, the key takeaway is that MDX is the language of ASO, while calculation scripts are the language of BSO.
Oracle Smart View for Office is the primary client tool for interacting with both BSO and ASO cubes. A deep knowledge of its capabilities is essential for the 1z0-531 Exam. Smart View is an add-in for Microsoft Excel, PowerPoint, and Word that allows for powerful ad-hoc analysis and reporting. Users can connect directly to an Essbase database and retrieve data into an Excel worksheet. Once the data is in Excel, users can leverage all of Excel's familiar formatting and charting capabilities.
The core feature of Smart View is ad-hoc analysis. Users can start with a blank sheet, select members from different dimensions, and retrieve the corresponding data. They can then pivot the dimensions between the rows, columns, and page, allowing them to slice and dice the data from various perspectives. They can also drill down from a parent member to see its children or drill up to see a summary level. This interactive analysis is incredibly powerful for exploring data and uncovering insights.
For BSO cubes, Smart View also supports data write-back. A user can enter their budget or forecast numbers into a formatted Excel grid and then submit that data back to the Essbase database. This is a very common workflow for planning and budgeting applications. Smart View also includes a function builder that allows you to embed functions in your spreadsheet that retrieve specific data points from the cube, enabling the creation of highly customized and formatted reports directly within Excel.
Securing the data in your Essbase applications is a critical responsibility for an administrator, and the 1z0-531 Exam covers the fundamentals of the Essbase security model. Security is typically managed through Oracle Shared Services, which is a centralized user and group management system for the Oracle EPM suite. The first step is to create users and provision them with roles that grant them access to Essbase and its various client tools.
Once a user has been provisioned, they can be assigned to groups. It is a best practice to manage security through groups rather than individual users, as this is much more scalable and easier to maintain. You can then grant these groups access to specific Essbase applications and databases. This application-level security determines which cubes a user is able to see and connect to. However, this is only the first layer of security.
The most granular layer of security is data-level security, which is managed through filters. A filter defines which dimension members a user or group can access. By creating and applying filters, you can control read, write, or no access to specific slices of the database. This ensures that users can only see and interact with the data that is relevant and appropriate for their role.
Data security filters are a core component of the Essbase security model and a key topic for the 1z0-531 Exam. Filters are created and managed within the EAS Console. A filter is an object that contains a set of access permissions for different dimension members. For example, you could create a filter for the "East Region Sales" group. In this filter, you might grant read access to the "East" member of the Region dimension and no access to all of its siblings (like "West," "Central," and "South").
You can define access at a very granular level. You can grant access to a member and all of its descendants, its children, or just the member itself. You can also specify the type of access: read, write, or none. For a planning application, a regional manager might be given write access to their own region so they can enter their budget, but only read access to other regions so they can see them for comparison.
Once a filter is created, it is assigned to a user or a group for a specific database. A user can have multiple filters assigned to them, and Essbase will combine them to determine their final effective permissions. It is important to design your security model carefully, as a large number of complex filters can have a negative impact on performance. However, they are essential for ensuring the confidentiality and integrity of your data.
