The Research Of Distributed Object-Oriented System Performance Design

Along with the development of network and object-oriented technology, Distributed Object-oriented technology is improved constantly, but the users make still greater demands on Distributed Object-oriented System. This paper starts with software design to find out some principles and design patterns that are suited to the distributed multi-tier object-oriented systems. The developers can effectively improve the performance of the software, and enhance the system's efficiency by using these principles and patterns perfectly.The optimization principles are realized in the development of Material Management System. This system is based on J2EE platform, using Weblogic Server 8.1 as Web server and application server, MS SQL Server 2000 as database server. The system performance is improved greatly by using these principles.
