摘要
为了解决客户端对数据库的透明访问以及数据库连接参数的安全性问题,提出了一种基于三层模式的数据库连接模型。该模型利用COM+的组件服务和MSMQ队列组件解决了客户端与数据库之间的透明通信问题,同时也在一定程度上保证了数据库连接参数的安全性。测试表明,基于该模型的三层应用系统具有较好的可扩展性、可维护性和可靠性。
The access to database is an important issue during the development of three-tier application system. In this paper, a database connection model based on three-tier architecture is brought out to realize the transparency of access to database and the security of database connection information. The model resolves the transparent communication issue between the client and database, using the COM＋ component service and MSMQ component. Tes tshows that a three-tier application system, which is based on this model, get better expansibility, maintainability,reliability and performance.
