Non-unique index name
Type a name for this index. The name must be valid for the DBMS that is implementing this database structure.
By default, the table name is concatenated with the "_IDX" suffix (or whatever suffix was set in the Database Modeling Preferences window) to form an index name that changes to reflect any changes in the table name.
If you enter a different name, Microsoft Office Visio does not automatically update it if the table name changes.
To restore the default index name behavior, type '' (two single quotation marks).
Unique constraint name
If the index has a uniqueness constraint, type its name.
