(Object Data Management Group, Burnsville, MN, www.odmg.org) An organization founded in 1991 to promote object database standards. Disbanded in 2001 after completing its objectives, the ODMG added programming extensions to C++ and Smalltalk for accessing object databases. It also included a superset of SQL 92 Entry Level, the most widely supported version of SQL. The ODMG defined an interface to the database, whereas the OMG (Object Management Group) defines an interface for objects in a distributed environment. The ODMG object model complies with the OMG standard (see CORBA).
