Database Tables – Completing the New or Save As form

Local data storage replaced data tables. Do not create new data tables.

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

Before you create a Database Table instance, verify the following details:

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

You do not need to create a Database Table instance for each concrete class. At run time, 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, the system uses the default table pr_other.

Database Table instances created automatically

You can use the following tools and wizards to create database tables indirectly, without using the Database Table form:

Connector and Metadata wizard — 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 Pega Platform class:

Field

Description

Class Name

Select the name of an abstract or concrete class to be linked with a database table.

Do not 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, which is the purpose of a class group.
