摘要
分布式多层B/S架构克服了C/S结构和局域网为中心、系统难以扩展、维护成本高、软件移植性差等缺点,它把表示逻辑、业务逻辑、数据库等操作分离开来,各层相对独立。这种多层分布式计算模型适应了企业应用的发展要求,使企业计算具有良好的可扩展性、可靠性、稳定性、安全性等特点。同时,通过组件(Component)技术的使用,缩短了系统开发的周期和降低了开发成本,大大降低了企业应用系统开发的复杂度。
The distributed multi-tier B/S structure overcome the shortcomings of C/S structure,as the center of LAN,the system is hardly to expand,high maintenance cost,and poor portability of software etc.which separated from the operations of presentation logic,business logic and database etc.,each hierarchy is independent respectively. This multi-tier distributed computing model adapted the requirements of applied development in enterprises,so as to compute in enterprises possessed the features of good expandability,reliability,stability and security etc. Meanwhile,through the use of Component technology,it＇s shortened the system development cycle and reduced the development costs as well as decreased greatly to the complexity of applied system development in enterprises.
