Database foundation classes

Some classes are known as foundation classes in the Pega Platform. These classes must stay in the pr4_base table as initially installed, with the Catalog and Schema fields blank. In addition, never change the database table mapplings for these classes.

The classes are:

  • Rule-Obj-Class
  • Data-Admin-DB-Table
  • Data-Admin-DB-Name
  • Data-Admin-DB-ClassGroup

Instances of these four classes are usually stored in the pr4_base table. They can be stored in another table specified in the database/baseTable entry in the prconfig.xml file or as specified in the base table Dynamic System Setting.
