Design and Realization of an Access Mechanism for an Object Oriented EDDBMS |
| |
| Abstract: | An access mechanism for the object oriented engineering database management system (EDDBMS) is described. According to the specific features of the object oriented semantic model, a storage model suitable for a class or an object is developed and a composite object indexing mechanism to be used to make possible the inquiry about the objects from a class hierarchy or a single class is proposed. With OID, the object inquiry is easy, and, based on these strategies, the storage management of the complex object is realized. |
