The Object Data Management Group (ODMG) is a group that was established in 1991 with the goal of advancing object database standards. Their contributions include programming extensions to C++ and Smalltalk for accessing object databases, as well as a superset of SQL 92 Entry Level that receives the most support.
While the Object Management Group (OMG) defines an interface for objects in a distributed context, the ODMG created an interface to the database. The ODMG object model meets the OMG standard, and the group achieved its goals before disbanding in 2001.
