Understanding the unique features of the Pega Platform database

Updated on April 5, 2022

The database and the tables within it are structured in a unique way. By understanding how the database is structured, you are better able to support system upgrades and to be responsive to changes in data utilization.

  • Configuring a split database architecture

    Pega Platform high availability is database-agnostic. The recommended database features are:

  • Viewing database tables and Pega Platform metadata by using the Clipboard tool

    Every persistent object in the Pega Platform database has an associated class ( Rule-Obj-Class rule type). The Pega Platform uses a simple algorithm and information in Data-Admin-DB-Table instances to determine which table contains objects of which classes.

  • Default database tables

    The Pega Platform contains database table ( Data-Admin-DB-Table ) data instances when it is initially installed. These instances are linked to various database tables and views in the Pega database, and are used to map classes or class groups to database tables or views.
