Providing views and closure for the object data management group object model

The ODMG Object Model uses a standard for object-oriented database designers,while attempting to address some issues of interoperability. This research is focusedon the viability of using the ODMG data model as a canonical data model in amultidatabase environment, and where weaknesses are identified we have proposedamendments to enable the model to suit the specific needs of this type of distributeddatabase system. This paper describes our eorts to extend its relational style alge-bra,and to provide query closure and a viewing mechanism for OQL to constructmultidatabase schemas
