Options to Configure a Predefined Database Object

You can configure a predefined extension table or column that is available for you to use for your own purposes. These tables and columns provide the easiest option to store more entities because they are already part of the data objects layer. Using them does not require you to modify the logical schema. The following predefined extensions are available:

• Extension columns

• One-to-one extension tables

• One-to-many extension tables

For more information, see Options to Use a Predefined One-to-One Extension Table and Options to Use a Predefined One-to-Many Extension Table.

You can use the Database Designer to add an extension column to a base table or to create a new one-to-one extension table. For more information, see Adding an Extension Column to a Base Table.
