What is PeopleCode?

PeopleCode is a proprietary programming language used within the PeopleSoft application suite, primarily for customizing and automating business processes. It is similar to other object-oriented programming languages and is tightly integrated with the PeopleSoft architecture, allowing developers to define business logic, validate data, and control the user interface. PeopleCode is often used to extend delivered functionality, create workflow processes, and integrate with other systems. Mastery of PeopleCode is essential for PeopleSoft developers and administrators who need to tailor applications to meet organizational needs.
