Preparing for the 1z0-632 Exam inherently deepens a team member's knowledge, benefiting every project they touch.
At the heart of any modern PeopleSoft system lies the PeopleSoft Internet Architecture, commonly referred to as PIA. Understanding this architecture is absolutely critical for anyone preparing for the 1z0-632 Exam, as numerous questions will test your knowledge of its components and their interactions. PIA is a multi-tiered system designed to deliver PeopleSoft applications over the web or an intranet. It consists of a web browser on the client side, a web server, an application server, and a database server. This distributed structure allows for immense scalability, flexibility, and platform independence.
The user interacts with the system through a standard web browser, which sends HTTP or HTTPS requests to the web server. The web server acts as an intermediary, forwarding these requests to the application server. The application server is the real workhorse, containing the business logic and PeopleCode that define the application's functionality. It processes the user's request, interacts with the database server to retrieve or update data, and then builds the resulting HTML page to be sent back to the user's browser via the web server. This entire process happens seamlessly, providing a rich user experience through a familiar web interface.
The web server is the entry point for all user interaction with the PeopleSoft application. Its primary responsibility is to handle the incoming HTTP requests from users' browsers and serve the static content like HTML, JavaScript, CSS, and image files. When a request requires dynamic content or business logic processing, the web server passes it on to the application server. For the 1z0-632 Exam, it is important to know that PeopleSoft uses web server software like Oracle WebLogic or IBM WebSphere to fulfill this role. The web server houses the PeopleSoft web services, which listen for these requests.
A key component residing on the web server is the Jolt servlet. This Java servlet acts as a bridge, translating the HTTP requests from the browser into a format that the PeopleSoft application server can understand. It then forwards these requests to the appropriate application server processes. Similarly, it receives the responses from the application server and translates them back into HTTP to be sent to the browser. This communication layer is fundamental to how PIA functions, enabling the stateless protocol of the web (HTTP) to interact with the stateful session-based processing of the application server.
The application server is the core engine of the PeopleSoft system, and a deep understanding of its functions is essential for the 1z0-632 Exam. It is responsible for executing all business logic, running PeopleCode, and managing SQL transactions with the database. The application server is not a single program but a collection of server processes, each designed for a specific task. These processes are managed by a domain, which is a configured instance of an application server. An organization might have multiple domains for different purposes, such as development, testing, and production.
Key server processes that you should be familiar with include PSAPPSRV, the main process that handles user requests and executes PeopleCode. PSQCKSRV and PSQRYSRV are used for handling quick queries and more complex queries, respectively. The application server also manages connection pooling to the database, which efficiently handles user sessions and database resources. It authenticates users, enforces security, and ensures that data integrity is maintained according to the rules defined within the application. Its ability to scale by adding more server processes or entire domains makes it suitable for enterprises of all sizes.
While the application server handles real-time user interactions, the Process Scheduler server is responsible for managing and executing batch processes. These are tasks that run in the background without direct user interaction, such as running large reports, performing calculations, or interfacing with other systems. A solid grasp of the Process Scheduler is a must for anyone taking the 1z0-632 Exam. It allows administrators to schedule processes to run at specific times, on a recurring basis, or immediately upon user request. This offloads long-running tasks from the application server, ensuring that online performance is not degraded.
The Process Scheduler has its own set of server processes, managed through a domain similar to the application server. When a user submits a request to run a process, the request is placed in a queue. The Process Scheduler polls this queue and, when resources are available, initiates the appropriate process. It supports a wide variety of process types, including COBOL programs, SQR reports, Crystal Reports, and, most importantly, Application Engine programs. It also manages the distribution of output files, directing reports to a report repository where users can access them, or sending them to printers or email addresses.
The database server is the final tier in the PeopleSoft Internet Architecture and serves as the central repository for all data. This includes not only the business transaction data (like employee records or financial entries) but also all the metadata that defines the PeopleSoft application itself. Every object you create in PeopleTools, such as records, pages, and PeopleCode, is stored in a set of tables within the database, known as the PeopleTools metadata tables. This is a crucial concept for the 1z0-632 Exam, as it underscores that the entire application is data-driven.
PeopleSoft supports various relational database management systems (RDBMS), including Oracle, Microsoft SQL Server, and IBM DB2. The application server communicates with the database server using SQL (Structured Query Language). All data access is managed through the application server, which ensures that security rules and data integrity constraints are enforced. Direct access to the database is generally discouraged to maintain the integrity of the application. The performance, security, and availability of the database server are paramount to the overall health and responsiveness of the entire PeopleSoft system.
PeopleTools provides a comprehensive integrated development environment (IDE) called Application Designer. This is the primary tool used by developers to create, modify, and manage the objects that make up a PeopleSoft application. A significant portion of the 1z0-632 Exam focuses on the practical use of Application Designer. It is a Windows-based client application that connects directly to the PeopleSoft database to access the metadata that defines the application. Within Application Designer, developers work with a wide variety of object types, which are known as definitions.
These definitions are the building blocks of the application. They include fields, which define the attributes of data; records, which represent tables in the database; pages, which are the user interfaces; components, which group pages together into a business transaction; and menus, which provide the navigation structure. Application Designer presents these definitions in a hierarchical project view, allowing developers to organize their work logically. Mastering the creation and modification of these core definitions is the first step toward becoming a proficient PeopleSoft developer and passing the 1z0-632 Exam.
To excel in the 1z0-632 Exam, you must be comfortable with the hierarchy and relationship between different PeopleTools objects. The most fundamental object is the field. A field definition specifies properties like data type, length, and formatting. Multiple fields are grouped together to form a record definition. A record definition corresponds directly to a table in the underlying database, and it is where the application's data is stored. Record definitions are categorized by type, such as SQL Table, View, or Derived/Work record, each serving a distinct purpose in the application.
Once records are defined, they are used to build the user interface. Fields from a record are placed onto a page definition. A page is the canvas where you arrange controls like text boxes, drop-down lists, and grids. However, a user never accesses a page directly. Pages must be grouped into a component. A component represents a complete business transaction, often containing multiple pages that a user can navigate between. Finally, components are registered and placed into menus, which ultimately appear in the portal navigation, allowing users to access the functionality you have built. This field-to-record-to-page-to-component structure is fundamental.
As we conclude this first part, it is clear that a strong foundation in PeopleSoft architecture and the basic object model is non-negotiable for the 1z0-632 Exam. You should be able to draw a diagram of the PeopleSoft Internet Architecture and explain the role of each server tier: web, application, process scheduler, and database. You must understand how a user request flows through these tiers and how the system processes it to return a result. This knowledge is not just for answering direct questions but also provides the context for more advanced development and administration topics.
Furthermore, a solid grasp of the definitions within Application Designer is essential. You need to know what a field is, how it relates to a record, how records are used on pages, and how pages are assembled into components. In the next part of this series, we will dive deeper into the practical aspects of working with these objects inside Application Designer. We will cover the creation and properties of records, the design of effective user interface pages, and the construction of components to encapsulate business logic, bringing you one step closer to success on your 1z0-632 Exam.
Application Designer is the cornerstone of PeopleSoft development, and a significant portion of the 1z0-632 Exam is dedicated to your proficiency with this tool. It is a rich, integrated development environment (IDE) that provides access to all PeopleTools definitions. When you launch Application Designer, you connect to a specific PeopleSoft database, giving you a direct line to the application's metadata. The main interface is organized into a project workspace, a definition workspace, and an output window. The project workspace is crucial for organizing your work, as it allows you to group related definitions for a specific task or customization.
Familiarity with the user interface is key. You must be comfortable opening different definition types, such as records, pages, and PeopleCode, and understand the specific editor that is used for each. The output window at the bottom is vital for seeing the results of validation checks, build processes, and comparison reports. Being able to efficiently navigate, search for definitions, and manage objects within a project will not only save you time in your day-to-day work but will also give you the confidence needed to tackle the practical questions posed in the 1z0-632 Exam.
Record definitions are the foundation of data storage in any PeopleSoft application. For the 1z0-632 Exam, you must understand the different types of records and their specific uses. The most common type is the SQL Table, which corresponds to a physical table in the database. When you create or modify a SQL Table record definition in Application Designer and run the build process, PeopleTools generates and executes the necessary SQL DDL (Data Definition Language) to create or alter the table in the database. This tight integration is a core feature of PeopleTools.
Other important record types include SQL View, which is based on an SQL query that can join multiple tables, and Derived/Work records. Derived/Work records are particularly important; they do not exist as physical tables in the database. Instead, their fields exist only in memory during a transaction. They are used to hold temporary data, store values for calculations, or control the behavior of the user interface. For example, a push button or a hyperlink on a page often needs to be associated with a field from a Derived/Work record. Understanding when to use each record type is a common topic in the 1z0-632 Exam.
Fields are the most granular and fundamental of all PeopleTools definitions. A field defines a single piece of data, including its type (character, number, date), length, formatting, and other properties. The 1z0-632 Exam will expect you to know how to create and manage field definitions. One of the powerful concepts in PeopleTools is the idea of field inheritance. When you add a predefined field to a record, the record field inherits the properties of the base field definition. This promotes consistency and reusability across the entire application.
For example, if you have a field called EMPLID for employee ID, you define its properties once. Then, every time you add EMPLID to a record, it will automatically have the same length, data type, and label. If you need to change a property, you can change it in the central field definition, and it can be propagated to all instances. You can also override properties at the record field level if a specific context requires it. This combination of reusability and flexibility is a key design principle in PeopleTools development that you must understand.
Once you add fields to a record definition, you must configure their properties and define the key structure. This is a critical task and a major subject for the 1z0-632 Exam. Each field within a record has a set of properties that control its behavior, such as whether it is a required field, has a default value, or is subject to table edits for validation. A table edit, for example, can specify that the value entered into a field must exist in a corresponding prompt table, ensuring data integrity at the point of entry.
The key structure of a record is paramount. You must designate one or more fields as key fields. These keys define the uniqueness of each row in the table and determine how the data is sorted. The 1z0-632 Exam will test your understanding of different key types, such as primary keys, alternate search keys, and list box items. Alternate search keys are particularly important as they are used to define the fields that appear in search dialogs, allowing users to look up records based on criteria other than the primary key. Properly defining keys is essential for both data integrity and application performance.
After creating or modifying a record definition of type SQL Table or View, the changes only exist in the PeopleTools metadata tables. To apply these changes to the underlying database, you must use the SQL Build process within Application Designer. This process is a frequent topic on the 1z0-632 Exam. The build process analyzes your record definition and compares it to the current state of the database. It then generates the appropriate SQL script containing commands like CREATE TABLE, ALTER TABLE, or CREATE VIEW.
You have several options when running the build process. You can choose to simply generate the script to a file for a database administrator to review and run later, or you can execute the script directly from Application Designer. The process also allows you to create or drop indexes and perform other database-level actions. Understanding the options in the Build dialog box, such as the "Create Tables" or "Alter Tables" settings, and knowing the potential impact of running a build process on a database with existing data is a core competency for any PeopleSoft developer.
Pages are the canvases upon which the user interface is built. In Application Designer, you create a page definition and then drag and drop controls onto it from a toolbar. These controls include standard elements like edit boxes, drop-down list boxes, check boxes, and push buttons. A crucial concept tested in the 1z0-632 Exam is that every data-entry control on a page must be associated with a specific record field. This direct binding is how the component processor knows where to save the data that a user enters.
Page design involves more than just placing controls. You must also consider the layout and user experience. You can use group boxes to visually organize related fields and scroll areas or grids to display multiple rows of data from a table. The properties of each page control allow you to customize its appearance and behavior. For instance, you can set a field to be display-only, invisible, or have its label text changed dynamically. Creating intuitive and functional pages is a key skill for any PeopleSoft implementer.
A user never interacts with a page directly. Instead, pages are accessed through a component. A component is a collection of one or more pages that represent a complete business transaction or logical unit of work. For the 1z0-632 Exam, you must understand how to construct a component and how its structure affects user interaction. When you add pages to a component, you define their order and set properties at the component level. The component definition also specifies the search record that will be used for the component's search page.
The structure of a component is based on scroll levels. Level 0 corresponds to the search keys and data that is fetched once for the entire component. Level 1, 2, and 3 correspond to data in scroll areas or grids, representing one-to-many relationships. For example, Level 0 might be a customer's information, while Level 1 could be a scroll area showing all of that customer's orders. This hierarchical data structure is fundamental to how PeopleSoft handles data and is managed automatically by the component processor based on the component's design.
Every component has a set of properties that dictate its behavior. One of the most important properties, and a key topic for the 1z0-632 Exam, is the definition of the search record. The search record determines which fields the user can search on to retrieve data into the component. When a user navigates to a component, PeopleSoft automatically generates a search page based on the designated search record and its alternate search keys. The fields you select as keys in the search record are what the user will see and use to find the specific transaction they want to view or edit.
Other component properties control the actions that are available to the user, such as Add, Update/Display, and Correction. By setting these properties, you can control whether users are allowed to create new records, edit existing ones, or view historical data. This is a primary mechanism for enforcing business rules and security at the transactional level. Understanding how to configure these properties is essential for building secure and functional PeopleSoft applications and for answering related questions on the 1z0-632 Exam.
Once a component has been created and saved, it is not yet accessible to users. The final step is to register the component within the portal navigation structure. This process involves several steps that are important to know for the 1z0-632 Exam. First, you create a content reference. A content reference is a portal object that points to your component and defines its menu label, its security authorizations, and other portal-related attributes. You create and manage content references using the portal administration pages within the PeopleSoft application itself, not within Application Designer.
These content references are then placed into folders, which create the hierarchical menu structure that users see when they navigate through the system. For example, you might place a content reference for your new "Employee Expense" component inside a folder called "Expenses," which is itself inside a folder called "Self-Service." The entire navigation structure is permission-list driven, meaning a user will only see the menu items and components for which they have been granted security access. This integration of development and security is a hallmark of the PeopleSoft framework.
PeopleCode is the proprietary, object-oriented programming language used to enforce business rules and implement custom logic within PeopleSoft applications. It is an indispensable skill for any PeopleSoft developer, and a deep understanding of its syntax and application is a major requirement for passing the 1z0-632 Exam. PeopleCode is not a standalone language; it is intrinsically tied to the PeopleTools object definitions. Code is associated with a specific definition, such as a record field or a component record, and it executes automatically when a predefined event occurs during the processing of a transaction.
The language itself is strongly typed and has a syntax similar to other popular application programming languages, making it relatively easy to learn for those with a background in development. It includes familiar constructs such as conditional logic (If-Then-Else), loops (For, While), and function calls. However, its true power lies in its deep integration with the PeopleSoft runtime environment. Through built-in functions and system variables, PeopleCode can seamlessly interact with data in the component buffer, manipulate page controls, and execute complex SQL statements, all within the context of the user's current transaction.
The most critical concept to grasp for the 1z0-632 Exam regarding PeopleCode is the event-driven model. You do not simply write a program and run it. Instead, you place your code in specific events that are fired by the component processor at various points during its processing lifecycle. For example, when a user changes the value in a field on a page, the FieldChange event for that record field is triggered. If you need to perform a calculation or validate the new value, you would place your code in this event.
There is a well-defined sequence of events that occurs as a user opens a component, adds a new row, saves their changes, and performs other actions. Key events include RowInit, which fires after the component processor has loaded data from the database into a row; FieldEdit, used for simple, field-level validation; FieldChange, for processing logic after a field's value has been altered; and SavePreChange and SavePostChange, which fire before and after the database update, respectively. Knowing which event to use for a specific type of logic is a skill that the 1z0-632 Exam will rigorously test.
To effectively write PeopleCode, you must be proficient with its fundamental syntax and data types. The 1z0-632 Exam will expect you to understand how to declare variables, use assignment statements, and work with different data types like String, Number, Boolean, and Date. PeopleCode provides a rich setta of built-in functions for manipulating these data types, such as functions for string parsing, date arithmetic, and mathematical calculations. Using these built-in functions is highly encouraged as they are optimized for the PeopleTools environment.
Control structures are also fundamental. You will need to write If-Else statements to control the flow of your program based on certain conditions. You will use For and While loops to iterate over rows of data in a scroll or grid. The Evaluate statement, which is similar to a Case or Switch statement in other languages, is another powerful control structure for handling multiple conditions efficiently. A solid understanding of these basic programming constructs is the foundation upon which all complex PeopleSoft logic is built.
The component buffer is a crucial concept for the 1z0-632 Exam. It is the area in the application server's memory where all the data for the current component transaction is held. When a user searches for and opens a component, the component processor retrieves the relevant data from the database and loads it into a hierarchical structure of rowsets, rows, records, and fields in the buffer. Your PeopleCode interacts primarily with this in-memory data, not directly with the database. This is a key principle of PeopleSoft development.
PeopleCode provides functions and object-oriented syntax to navigate and manipulate this data. For example, you can get a reference to the current row, loop through all the rows in a scroll area (a rowset), and get or set the value of any field in the buffer. When the user saves the transaction, the component processor compares the data in the buffer with the original data fetched from the database and automatically generates the necessary SQL INSERT, UPDATE, and DELETE statements. Your PeopleCode logic, therefore, focuses on the business rules rather than the low-level data access.
While much of the day-to-day coding involves procedural logic within events, PeopleCode is also a fully object-oriented language. The 1z0-632 Exam requires you to be familiar with using PeopleTools-supplied classes. These classes provide an object-oriented interface to various parts of the PeopleSoft system. For instance, there are Rowset, Row, Record, and Field classes that allow you to programmatically navigate and manipulate the component buffer. There are also classes for working with SQL, files, and even for creating and sending emails.
A particularly important set of classes are the SQL classes (CreateSQL, &SQL.Fetch, &SQL.Execute). These allow you to execute SQL statements that are not automatically handled by the component processor. You might use the SQLExec function for simple, single-row lookups, but for more complex operations that process multiple rows of data, the SQL classes provide a more powerful and flexible solution. Understanding how to instantiate these classes, call their methods, and use their properties is a key skill for advanced PeopleSoft development and a topic you should be prepared for.
Providing clear feedback to users is a critical part of application development. PeopleCode includes built-in functions specifically for issuing error and warning messages. The 1z0-632 Exam will expect you to know the difference between the Error, Warning, and MessageBox functions and when to use each. The Error function is the most severe; it stops processing immediately, highlights the field in error, and displays a message to the user. The transaction cannot be saved until the error is corrected. This should be used for critical data validation.
The Warning function, on the other hand, displays a message and presents the user with an "OK" and "Cancel" choice. If the user clicks "OK," processing continues; if they click "Cancel," the transaction is halted. This is used for situations where the data might be unusual but is not necessarily incorrect. The MessageBox function is more general-purpose and can be used to display informational messages or ask more complex questions with multiple button choices. Using these functions appropriately is key to creating a user-friendly and robust application.
PeopleTools provides an extensive library of built-in functions that perform a wide range of tasks, and familiarity with the most common ones is essential for the 1z0-632 Exam. These functions are categorized by purpose, such as functions for date manipulation, string handling, and mathematical operations. For example, functions like Substring, Len, and Upper are used for working with strings, while AddToDate and Days are used for date calculations. There are also functions for interacting with the user interface, like Hide and Unhide, which can dynamically control the visibility of page controls.
Beyond these general-purpose functions, there are context-specific functions for interacting with the component buffer, such as GetRowset, GetRow, and GetRecord. These are the primary tools for navigating the data structure of your component. Another important category is the set of functions that provide information about the current context, such as %Component, %Page, and %UserId, which return the name of the current component, page, and the ID of the logged-in user, respectively. Leveraging these built-in functions is far more efficient than writing the logic from scratch.
A significant amount of PeopleCode logic involves interacting with the database to fetch supplemental information or perform updates outside of the main component save process. The 1z0-632 Exam will test your ability to correctly embed SQL within your PeopleCode. The simplest way to do this is with the SQLExec function. SQLExec executes a single SQL statement, typically a SELECT that returns one row, or an INSERT, UPDATE, or DELETE statement. It is a powerful and convenient function for quick database interactions.
However, SQLExec has limitations. It cannot be used to fetch and process multiple rows of data. For those scenarios, you must use the PeopleCode SQL classes (&SQL). These classes allow you to open a cursor on a SQL statement, loop through the resulting rows using a Fetch method, and process each row individually. This approach is more complex but is also more efficient and scalable for handling larger data sets. Knowing the difference between SQLExec and the SQL classes, and understanding the performance implications of each, is a hallmark of an experienced PeopleSoft developer.
No developer writes perfect code on the first try, and knowing how to debug your logic is a critical skill tested implicitly by the 1z0-632 Exam's scope. PeopleTools offers several powerful tools for this purpose. The first is the PeopleCode debugger, which is built into Application Designer. It is a full-featured, interactive debugger that allows you to set breakpoints in your code, step through it line by line, inspect the values of variables, and monitor the state of the component buffer. This is the most effective tool for troubleshooting complex logic.
Another invaluable tool is tracing. You can enable various traces through the PeopleSoft configuration pages or by adding a URL parameter. The PeopleCode trace will generate a detailed log file that shows every statement that was executed, the events that fired, and the values of variables at different points. The SQL trace is equally important, as it shows every SQL statement that was sent to the database by the PeopleSoft runtime. Analyzing these trace files is often the quickest way to diagnose performance problems or understand why the system is behaving in an unexpected way.
While components and PeopleCode are used to build the online, user-facing parts of a PeopleSoft application, Application Engine is the primary tool for creating background or batch processes. A thorough understanding of Application Engine is a major component of the 1z0-632 Exam. Application Engine programs are used for tasks that involve processing large volumes of data, such as calculating payroll, posting financial journals, or loading data from an external system. These programs are designed to be efficient, restartable, and can be scheduled to run via the Process Scheduler.
An Application Engine program is not a single block of code. Instead, it is structured into a hierarchy of sections, steps, and actions. A section is a logical unit of work, and it contains one or more steps. A step is the smallest unit that can be committed to the database. Each step, in turn, consists of one or more actions. These actions can be of different types, including executing a SQL statement, calling another section, or executing a block of PeopleCode. This modular structure allows for complex business processes to be broken down into manageable and reusable parts.
To succeed with Application Engine questions on the 1z0-632 Exam, you must be intimately familiar with its structure. The top-level definition is the Program. Every program must have at least one section called MAIN. This is the entry point where execution begins. From this main section, you can call other sections to perform specific tasks. This allows for a structured, top-down programming approach. Within a section, you have steps. The concept of a step is critical because database commits are typically performed after each step is successfully completed.
Within a step, you have actions. The most common actions are SQL, PeopleCode, Log Message, and Call Section. A SQL action is used to perform set-based processing, which is highly efficient for updating or inserting large numbers of rows. A PeopleCode action is used when you need procedural, row-by-row logic that cannot be accomplished with a single SQL statement. This structured approach not only makes the program easier to develop and maintain but is also key to one of Application Engine's most important features: restartability.
One of the most powerful and frequently tested features of Application Engine on the 1z0-632 Exam is its ability to be restarted. If a long-running batch program fails midway through its processing, you do not want to start over from the beginning. Application Engine's restart capability allows the program to resume from the last successfully committed point. This is made possible through the use of a State Record. A State Record is a dedicated PeopleSoft record definition, typically a SQL Table, that is associated with an Application Engine program.
The fields in the State Record are used to hold key values and processing parameters for the program. As the program executes, it updates values in the State Record. Because commits happen at the end of each step, the values in the State Record are always in sync with the program's progress. If the program fails, the Process Scheduler can restart it. The Application Engine runtime will re-read the values from the State Record and use them to determine where to resume processing, skipping the steps that have already been successfully completed. Proper design of the State Record is crucial for robust batch processing.
A core principle of efficient Application Engine programming, and a key topic for the 1z0-632 Exam, is the preference for set-based processing over row-by-row processing whenever possible. Set-based processing operates on an entire set of rows with a single SQL statement (UPDATE or INSERT ... SELECT), which is significantly faster than fetching each row, processing it with PeopleCode, and then updating it. SQL actions in Application Engine are the primary mechanism for performing set-based operations.
However, there are times when row-by-row logic is unavoidable. For these scenarios, Application Engine provides a specific type of Do loop called Do-Select. A Do-Select action executes a SELECT statement to fetch a set of rows into the program's State Record. It then loops through the result set, executing the subsequent actions within the loop for each row that was fetched. This is the standard pattern for row-by-row processing in Application Engine and is used when complex, procedural logic is required for each individual row of data.
Component Interface is a powerful PeopleTools technology that allows you to interact with a PeopleSoft component programmatically, without using the graphical user interface. It is a critical tool for integrations and data loading, and its concepts are essential for the 1z0-632 Exam. A Component Interface is an object-oriented, API-like wrapper around a standard PeopleSoft component. It exposes the data and logic of the component through a set of properties and methods. This means you can write code (in PeopleCode, Java, or C++) that simulates a user entering data into the component's pages and saving it.
The huge advantage of using a Component Interface is that it automatically executes all the business logic, validation, and PeopleCode that is associated with the underlying component. This ensures that any data entered through the Component Interface is subject to the exact same rules as data entered by a user online. This guarantees data integrity and leverages all the development work that has already gone into building the component. It is the preferred method for loading data into PeopleSoft from external systems.
The process of creating a Component Interface is straightforward and is a likely subject for questions on the 1z0-632 Exam. You create a new Component Interface definition in Application Designer and simply drag and drop the desired component onto it. PeopleTools will then automatically inspect the component and create a corresponding set of properties for the fields and rowsets that are present in the component's buffer structure. You can then choose which properties to expose to the outside world.
Once the Component Interface is created, Application Designer provides a built-in tester. This tester allows you to interact with the Component Interface in a way that simulates how a program would use it. You can provide key values to retrieve an existing record (Get method) or create a new one (Create method). You can then view and change the property values and call the Save method. The tester will show you whether the save was successful or if any errors were triggered by the component's underlying business logic. This is an invaluable tool for debugging the CI and the underlying component's code.
While Component Interfaces can be accessed by external languages, their most common use within a PeopleSoft application is through PeopleCode, typically within an Application Engine program. The 1z0-632 Exam will expect you to know the standard PeopleCode pattern for working with a Component Interface. First, you must get a session handle to the CI. Then, you instantiate the CI object itself. You can then set the keys and call the Get() method to load data, or you can call the Create() method to prepare for a new entry.
After getting the CI object, you navigate its structure of collections (rowsets) and properties (fields) to set the data values. For example, you might read data from a flat file and assign those values to the corresponding CI properties. Once all the data is set, you call the Save() method. This triggers all the underlying component's logic, including default value processing, field edits, and SaveEdit, SavePreChange, and SavePostChange PeopleCode. Finally, you must check the return status of the save and handle any error messages that may have been generated by the business logic.
PeopleSoft provides a robust and layered security model, and understanding its core components is mandatory for the 1z0-632 Exam. The fundamental building blocks of PeopleSoft security are User Profiles, Roles, and Permission Lists. A User Profile is the unique definition for each person who logs into the system. It contains their user ID, password, and other personal settings. However, a User Profile is not granted security access directly. Instead, security is granted through the use of Roles.
A Role represents a job function or a set of responsibilities within the organization, such as "Accounts Payable Clerk" or "HR Manager." You assign one or more Roles to each User Profile. The Roles themselves do not contain the detailed security settings. They act as a container for one or more Permission Lists. The Permission List is where the actual security authorizations are defined. This three-tiered structure (User -> Role -> Permission) provides a flexible and maintainable way to manage security for thousands of users and objects.
The Permission List is the heart of PeopleSoft security, and the 1z0-632 Exam will require you to know what can be secured within one. A Permission List is a collection of authorizations that grant access to various parts of the system. This includes access to menus and components, which is known as portal security. You can specify exactly which components a user with this permission can access and what actions (Add, Update/Display, Correction) they are allowed to perform.
Permission Lists also control access to other PeopleTools objects. You can grant access to run specific batch processes through Process Security. You can authorize access to Component Interfaces, Web Services, and Query trees. A particularly important area is Data Security, which is managed through the security views associated with search records. This allows you to restrict the rows of data a user can see. For example, you can ensure that a manager can only see data for the employees who report directly to them. Understanding the different tabs and settings within the Permission List component is essential.
PeopleSoft Query is an end-user reporting tool that allows users to generate ad-hoc queries against the PeopleSoft database without needing to know SQL. It provides a graphical user interface for selecting tables (records), choosing fields, and defining criteria. A deep understanding of how to build and manage queries is a core competency tested on the 1z0-632 Exam. While it is designed for functional users, developers and administrators are responsible for setting up the underlying security and creating more complex queries that can be used as data sources for other processes.
When a user creates a query, they are not directly accessing the database tables. Instead, they are accessing the PeopleSoft record definitions. This is an important distinction because it means the query tool automatically enforces the PeopleSoft security model. Users will only see the records and fields they are authorized to access. The tool automatically handles table joins based on predefined key relationships, simplifying the process for users who are not database experts. The output of a query can be viewed online, downloaded to Excel, or used as a data source for other reporting tools.
