The Table Index Editor

In the physical model, you can use the Table Index Editor to perform the following tasks:

Create, rename, or delete an index
View the indexes for a table
View the properties of an index
Use the Members tab to view all the available columns in the table and those columns already assigned to the index

Depending on the target database, other index properties may be available.

Note: By default, the Primary Key index is automatically created. It is unique and includes all primary key columns.
