Abstract: Contrary to conventional databases the conceptual schema of an object-oriented database contains the description of the operations on the data next to the description of the structures of the data. Therefore a design method for such a database must consider the behavioral aspects of real world objects. The authors present such a method. It is based on the Behavior Integrated Entity Relationship Approach. The structural aspects are represented by entity sets, the behavioral aspects, by activities which correspond to transitions in an entity-state/transition diagram, which is based on a Petri net graph representation.
Keywords: object-oriented database; entity relationship approach; state/transition diagram.
