6th IASTED International Conference on Software Engineering and Applications, SEA 2002
作者: Chen, Yangjun Dept. Business Computing Winnipeg University 515 Portage Ave. Winnipeg MB R3B 2E9 Canada
Although object-oriented database systems offer more powerful modeling capability than relational database systems, their performance suffers from the increased complexity in the data model. Recently, a lot of researc... 详细信息
