摘　　要：三层架构降低了系统性能,可能导致级联的修改,为此提出一种改进的三层架构,即数据接口三层架构。给出数据接口和数据池的概念以及数据接口三层架构的基本原理,讨论该架构的优点,将该架构用于一个图书管理系统登录模块的开发。应用结果表明,该体系结构可以增强系统的性能、可重用性和可拓展性,解决了级联修改的问题。Three-tier architecture compromises the performance of system and may lead to cascading changing.To solve the problem,improved three-tier architecture,namely data interface three-tier architecture was proposed.The concepts of data interface and data pool,and the basic principles of this architecture were given.The advantages of this architecture were discussed,and the architecture was used in the development of login module of a book management system.The results show that this architecture can enhance the performance of system,reusability and extendibility and solve the cascading changing problem.
