DODBMS/CIM: a distributed object-oriented database management system for CIM applications

With the coming of advanced database applications such as CIM (computer integrated manufacturing), the conventional database systems (e.g. relational, network and hierarchical) are no longer adequate for the new requirements. One of the most promising approaches is the object-orientation concept. We present DODBMS/CIM (Distributed Object-oriented Database Management System for CIM applications). We adopt OSAM* (Object-oriented and Semantic Association data Model) as its global data model to support the rich semantics and complex data elements in CIM. Also, we adopt an open architecture and flexible transaction processing. In this paper, we present the system architecture, the global data model and language, and the implementation techniques of global transaction management and global query optimization.<>
