Object Management Extension is an option that enables you to add data types and SQL functions to the DBMS Server.

You can use a user-defined data type in any context in which you can use a standard Ingres data type, including with Ingres Star. You can use user-defined SQL functions in queries to manipulate both user-defined data types and standard SQL data types. To support your new data types and functions, you can add new capabilities to existing SQL comparison and arithmetic operators.
