A Peoplesoft database is expression which point out a database containing Peoplesoft objects. For Oracle and only for Oracle, Peoplesoft consists in 3 schemas namely:

- PS (PSDBOWNER table owner),

- PEOPLE (for connection checking) and

- SYSADM (by default), the last one contains all the objects/data.

One of the database objects is connected with single Oracle schema, and all processes that connect to the database use the standard PSFT login procedure. PSFT login is used because to refer to the collection of tables in the administrative schema within an Oracle database. Every process that makes a 2-tier connection to the database identifies itself with a PSFT user or operator ID. Hence the interaction goes.

Peoplesoft Database is similar to other database which is used to store data. Peoplesoft database stores data in a table format for system PeopleTools and Application tables. This is independent of the process you use to retrieve that data from PeopleSoft. Inside PeopleSoft database, only three types of tables reside inside the schema: System Catalog tables, PeopleTools tables, and Application data tables. Two of these table types, System Catalog and PeopleTools tables, can be referred to as metadata tables; users make use of Application data tables to store the data they need for their processes.
