Purpose

A class group data instance unifies a set of classes in the PegaRULES database that share a common name structure and common key structure. A class group causes all instances of these classes to be stored in one database table, As a result, processing can later convert an instance of any member class from its current class to another class within the class group, without affecting the key structure or changing the database table that holds the instance.

Class groups are primarily used to group a set of related subclasses of the Work- base class; such class groups are also known as work pools.

For example, a work object created from a scanned document may initially be assigned to a general work type. After a worker reviews and classifies the work object, she may convert it to a more specific type. Ordinarily, both the general and the specific work types belong to one work pool (one class group), so the "conversion" does not affect the key of the work object, and does not require moving the object from one table to another in the PegaRULES database.

Access

Use the Rules Explorer to list class groups on your system.

Where referenced

Class groups are referenced in access groups. They allow users or other requestors access to the work objects in work pools.

Automatic generation

Class groups can be created automatically — without using the Class Group form — in the Application Accelerator and from the Class rule form.

Database table

Class group data instances are always stored as rows of the pr4_base table.
