Change management in object-oriented databases

The author addresses two of the key issues of change management in advanced application databases that are reuse of objects in a changed environment and change propagation. Changes usually propagate along certain relationships between object in many advanced application databases. A database model is proposed called an active h-graph object model (AHOM), to address change management in object-oriented databases. AHOM is unique in its ability to represent every object in a database as a communicating agent in the object´s dynamic environment, and consequently, changes are represented and controlled through the dynamic environments of the objects in the database. It is shown that AHOM may be used to manage changing objects in advanced application databases
