PeopleTools ATT: Key Features, Benefits, and How it Works


PeopleSoft, a comprehensive software suite from Oracle, is widely used by organizations to manage various business functions, including human resources, finance, and supply chain management. At the heart of PeopleSoft lies PeopleTools, a robust set of tools that enable users to develop, customize, and maintain PeopleSoft applications efficiently. One of the standout components within PeopleTools is the Application Technology Tools (ATT), also known as the Application Engine and Application Designer.

Understanding PeopleTools ATT

PeopleTools ATT is designed to provide developers with a versatile and efficient platform to design, develop, and execute batch-processing applications. It plays a pivotal role in automating complex business processes that involve multiple steps, intricate logic, and diverse data sources. The core objective of PeopleTools ATT is to facilitate the creation of batch programs that can handle large volumes of data systematically and automatically. These programs are crucial for tasks such as data extraction, transformation, and loading (ETL) and for executing routine business processes that do not require real-time user interaction.

Key Features of PeopleTools ATT

One of the central components of PeopleTools ATT  is the Application Engine. This engine allows developers to design batch-processing programs using PeopleCode, a proprietary scripting language for PeopleSoft applications. Application Engine programs break down complex business processes into manageable steps, each with its instructions and logic. This structured approach simplifies the development and execution of batch programs, ensuring that tasks are completed efficiently and accurately.

Another integral part of PeopleTools ATT is the Application Designer. This graphical development environment enables developers to create, modify, and manage PeopleSoft applications easily. Within Application Designer, developers can design the structure of Application Engine programs, define data structures, and establish relationships between different components. This visual interface simplifies the development process, making it accessible even to those with limited programming experience.

Benefits of PeopleTools ATT

The efficiency and performance of PeopleTools ATT are among its most significant benefits. By breaking down complex processes into smaller, manageable steps and leveraging parallel processing capabilities, PeopleTools ATT enhances the efficiency and performance of batch processing applications. This is crucial for organizations dealing with large datasets and time-sensitive operations.

Flexibility and customization are also critical advantages of PeopleTools ATT. It provides developers with the flexibility to customize batch programs according to the specific requirements of their organization. Through Application Design, developers can design, modify, and enhance Application Engine programs to meet evolving business needs.


PeopleTools ATT is a cornerstone for organizations leveraging PeopleSoft solutions. Its Application Engine, coupled with the robust capabilities of an Application Designer, empowers developers to create efficient, customized batch-processing applications that can handle diverse business requirements. As organizations grow and evolve, the need for streamlined and automated batch processing becomes increasingly critical. PeopleTools ATT addresses this need and provides a platform for innovation and adaptability. By understanding the intricacies of PeopleTools ATT, organizations can unlock the full potential of their PeopleSoft applications, driving efficiency, performance, and, ultimately, success in their business operations.
