• Object databases suffered because of a lack of standardization : although standards were defined by ODMG, they were never implemented well enough to ensure interoperability between products.
• The primary goal of the ODMG was to put forward a set of specifications that allowed a developer to write portable applications for object database and object-relational mapping products.
• In 2004, the Object Management Group ( OMG ) was granted the right to revise the ODMG 3.0 specification as an OMG specification by the copyright holder, Morgan Kaufmann Publishers.
• "' Object Definition Language "'( "'ODL "') is the specification language defining the interface to object types conforming to the ODMG Object Model.
• In February 2006, the Object Management Group ( OMG ) announced that they had been granted the right to develop new specifications based on the ODMG 3.0 specification and the formation of the Object Database Technology Working Group ( ODBT WG ).
