| 摘 要： | 基于Web的分层模型设计在软件设计开发中已受到人们的广泛关注，已研究和应用了2层、3层结构，并取得了很多应用成果。然而，它不能很好地解决负载不均衡问题，且各层在逻辑上仍不具有独立性，致使应用系统维护困难。提出了一种基于．NET的四层结构应用模型：显示层、业务逻辑层、数据访问层以及数据库，逻辑层次清晰、耦合度低。经研究生综合信息系统开发实践，不仅提高了软件了的质量、增强了可雏护性，而且负载均衡。和3层结构相比，负载能降低24．32％。

| Abstract: | The design of tier model based on Web is concerned widely in the Scope of software development,two-tier and three-tier structure are studied and applied,and many application harvest are gained.However,it can not solve load imbalance problem,and these levels have not logical independence.It leads to maintainability is difficulty for system.A four-tier structure model is proposed,it is showing tier,operation logic tier,date visiting tier and database.They have clearer logic-tier,lower coupling.A graduate student integration information system is developed,the result show quality of software and maintainability are improved.Load is more balanceable than three-tier,it may reduce 24.32%. |
