In this paper, a flexible specification of signaling protocol based on an object-oriented call mode is proposed. The article’focuses on the protocol’s message syntax, message flow model, and applicability for defining multimedia and multiparty services.’展开更多

In this thesis, we describe the necessary capabilities for database management systems and compare them with the limitation of RDB. And also we introduce object database and its efficiency, which will be the new trend of the database. We use “Jasmine2000” as a concrete example of object database in business use, and are going to verify its efficiency with its applied cases. At the end, we will point the way of database's future.展开更多
