三层架构技术开发WEB应用项目的研究与实践

Research & Practice on WEB Application Project in the Technological Development of 3-layer Architecture

文中针对三层架构技术进行研究,分析了基于C#.NET开发平台的三层架构技术优势。阐述了三层架构体系的表现层(UI)、业务逻辑层(BLL)、数据访问层(DAL)各层的功能及依赖关系。然后结合运输企业管理系统中的车辆管理模块,采用三层架构体系进行程序设计,详细介绍该功能模块的实现过程。旨在让读者深刻领会到三层架构技术在松散关注、松散耦合、逻辑复用、提高开发效率等方面的优势。

In this paper,three layer architecture technology research,analysis of the three layer architecture technology based on C#.NET platform. The user interface layer（UI）,business logic layer（BLL）,data access layer（DAL）the function of each layer and dependence. Then combined with the vehicle management module and transportation business management system,using the three layer architecture program design,realization of the function module are introduced in detail. Designed to give readers a deep understanding of the three layer architecture technology in loose,loose coupling,pay attention to logic reuse,and improve the efficiency of the development advantages.
