Create a Database Table data instance by selecting Database Table from the SysAdmin category.

Before you create a Database Table instance, confirm that:

• The table or view is present in the database schema
• The PRPC class (Rule-Obj-Class instance) exists.

You don't need to create a Database Table instance for each concrete class. At runtime, to locate a database table for an object, the system uses pattern inheritance and class groups to locate the appropriate table. If none is found, it uses the "catch-all" default table pr_other.

Database Table instances created automatically

The following tools and wizards let you create database tables indirectly, without using the Database Table form:

• Application Accelerator — Optionally creates a table in the PegaRULES database for the work items and another table for work history, with corresponding database table instances.
• Connector and Metadata Accelerator — Creates a class and database table instance for an external table
• Database Class Mappings gadget — Creates a class and database table instance for an external table
• Data Tables wizard — Optionally creates a dedicated table in the PegaRULES database, and a corresponding database table instance, to hold the rows of the data table.

The key to a Database Table instance is the name of a PRPC class:

Field	Description
Class Name	Select the name of an abstract or concrete class to be linked with a database table. Don't create a Database Table instance for a class that is a subclass of a container class of a class group; it will be ignored. All instances (that is, all table rows) of all classes in a class group are stored together in one table; that is the purpose of a class group.
