PeopleTools is the name of the 4GL originally created by PeopleSoft as the tooling for customizing its ERP suite.
The new version, Oracle PeopleTools 8.48, finishes the job of SOA compliance with native support of baseline web services standards such as WSDL, UDDI, WS-Security, BPEL, and WS-Addressing.
Previously, you could have still web service enabled PeopleSoft application messages through PeopleTools, but you would have required external adapters to actually convert the APIs to WSDL.
