Defining constraint definitions in Data Administration

Use the procedures described in the following sections to define constraint definitions in Data Administration:

• Defining a primary key constraint definition
• Defining a unique key constraint definition
• Defining a foreign key constraint definition
• Defining a check constraint definition

The dialog boxes for defining primary, unique, and clustered index constraint definitions contain a common section that displays current settings for both OpenEdge properties and defined constraint definitions, a sample of which is shown in the following figure .

Possible values for each field are:

• C — A C in a column indicates that a constraint definition of this type is currently defined. The constraint definition can be created in the foreign database if you configure your migration to migrate constraint definitions.
• I — An I indicates that the property is currently defined your OpenEdge database.
