PeopleSoft is an integrated software package that provides business applications like HR, CRM, and financials. It was founded in 1987 and focuses on efficient enterprise-wide processes. PeopleSoft uses a server-centric architecture called PIA without a client, consisting of web, application, and database servers. Requests are sent through the web server to the application server which processes the request using services and returns the response through the web server to the client. Oracle acquired PeopleSoft in 2005 and is integrating it with its other applications under the Oracle Fusion platform.
