About Class Group data instances

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 item created from a scanned document may initially be assigned to a general work type. After a worker reviews and classifies the work item, 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 item, and does not require moving the object from one table to another in the PegaRULES database.
Use the Records Explorer to list class groups on your system.
Class groups are referenced in access groups. They allow users or other requestors access to the work items in work pools.
Class groups can be created automatically — without using the Class Group form — from the Class rule form.
The Data-Admin-DB-ClassGroup class contains class group data instances. They are part of the SysAdmin category.
Class group data instances are always stored as rows of the pr4_base table.
When you save a class group, if the Associated RuleSet is [none], the system completes this field with a RuleSet from the current application. This association assists with application packaging. You can update the associated RuleSet using the field in the upper right corner of the form. See Identifying parts of rule and data forms.
If there is no RuleSet associated with the data instance (for example, for existing instances not previously associated with a RuleSet), the Associated RuleSet displays [none].
