PeopleTools: A Complete Guide PeopleSoft’s Dev


In the world of enterprise software, “PeopleTools” is a term that often comes up, especially when discussing Oracle’s PeopleSoft applications.

This powerful suite of tools forms the technology backbone of PeopleSoft, providing a comprehensive platform that enables the rapid and flexible development of business applications.

In this article, we will delve into the intricacies of PeopleTools, exploring its features, benefits, and pivotal role in driving business efficiency and productivity.

A. Brief Overview of PeopleTools

In the world of enterprise software, PeopleTools stands as a cornerstone. It’s a proprietary software development environment originally created by PeopleSoft Corporation.

PeopleTools provides the underlying technology for all PeopleSoft applications, making it a vital part of the PeopleSoft ecosystem.

B. Its Origin and Acquisition by Oracle Corporation

PeopleSoft Corporation, the original creator of PeopleTools, was a prominent player in the Enterprise Resource Planning (ERP) software market.

However 2004, Oracle Corporation acquired PeopleSoft, bringing PeopleTools under its broad umbrella. Since then, Oracle has continued to develop and enhance PeopleTools, maintaining its relevance in the ever-evolving software landscape.

Understanding PeopleTools

A. Explanation of What PeopleTools Is

PeopleTools is a suite of tools, utilities, and technologies that facilitate the deployment of applications using an Internet-based architecture known as the PeopleSoft Internet Architecture (PIA). It’s a comprehensive development environment that enables developers to build, customize, and deploy PeopleSoft applications.

B. The Role of PeopleTools in Deploying Applications

PeopleTools plays a crucial role in deploying applications. It provides the infrastructure to run PeopleSoft applications on various platforms and databases.

With PeopleTools, developers can create platform-independent applications, meaning they can run on various operating systems and databases without requiring any modifications.

C. The Primary Language and Integrated Development Environment (IDE) Used in PeopleTools

PeopleTools primarily uses a proprietary language called PeopleCode. PeopleCode is an object-oriented, event-driven programming language designed to be easy for developers and non-developers.

The primary IDE used in PeopleTools is the Application Designer. This tool provides a graphical interface for creating and modifying PeopleSoft applications. It allows developers to create and customize various objects, including fields, records, pages, and components.

Core Applications of PeopleTools

A. List and Brief Explanation of Core Vendor-Developed PeopleTools Applications

PeopleTools provides the foundation for several core PeopleSoft applications, including:

  1. Human Capital Management (HCM): This application helps organizations manage their human resources, from hiring and onboarding to payroll and benefits administration.
  2. Financials and Supply Chain Management (FSCM): This application supports financial and supply chain processes, including accounting, procurement, and inventory management.
  3. Campus Solutions (CS): This application is designed for higher education institutions, supporting processes like student enrollment, financial aid, and academic advising.

B. The High Level of Abstraction Used in PeopleTools

One of the critical features of PeopleTools is its high level of abstraction. This means that developers can create applications without worrying about the specifics of the underlying hardware or operating system.

This makes PeopleTools applications highly portable, as they can run on various platforms without requiring modifications.

The Role of Application Designer

A. Explanation of What Application Designer Is

Application Designer is the primary tool used to create and customize PeopleSoft applications. It’s a graphical interface allowing developers to create and modify various objects, including fields, records, pages, and components.

B. The Functions That Can Be Undertaken in Application Designer

Application Designer supports a wide range of functions, including:

  1. Field Definition: Developers can define the fields that make up a record, specifying the field type, length, and other properties.
  2. Record Definition: Developers can define the records that make up a database table, specifying the fields that make up the record and their order.
  3. PeopleCode: Developers can write PeopleCode to define the behavior of fields, records, pages, and components.
  4. Page Definition: Developers can define the layout of a page, placing fields and other elements on the page.
  5. Component Definition: Developers can define the components that make up an application, specifying the pages that make up the component and their order.


A. Recap of the Importance and Role of PeopleTools in Application Development

In conclusion, PeopleTools is a vital part of the PeopleSoft ecosystem. It provides the underlying technology for all PeopleSoft applications, enabling developers to easily create, customize, and deploy applications.

Whether working with Human Capital Management, Financials, Supply Chain Management, or Campus Solutions, PeopleTools provides the tools and technologies you need to succeed.

B. Final Thoughts on How PeopleTools Facilitates the Deployment of Both Vendor-Developed and Custom-Developed Applications

PeopleTools not only supports vendor-developed applications but also facilitates the deployment of custom-developed applications. With its high level of abstraction, PeopleTools allows developers to create platform-independent applications, making it easier to deploy applications across various platforms.

Whether you’re a seasoned developer or a novice, PeopleTools provides a robust and flexible environment for application development.

In the world of enterprise software, understanding PeopleTools is crucial. It’s more than just a development environment—it’s a key to unlocking the full potential of PeopleSoft applications.

So, whether you’re looking to customize an existing application or create a new one from scratch, PeopleTools has got you covered.
