Abstract
(English)
An approach for supporting physical independence in Object Databases Servers is proposed in this paper. While in current implementations the strategy for storing data objects reflects the logical object definitions, a certain degree or independence in the physical database organization would be essential to meet specific performance requirements. In this paper, a canonical object data model and a storage object data model are presented. In the list, the objects are organized in c1asses; in the second, physical objects with similar structures are grouped in collections. Mechanisms for mapping data structures and operations from the logical level to the physical level are discussed
