可扩展三层B/S体系结构研究和应用

随着互联网和软件开发结构的不断发展,B/S结构具有比C/S结构更好的开放性和可扩充性,实现了瘦客户端模式,已经逐渐成为流行的体系结构.在实现B/S结构方面有多种解决方案,文章结合实际应用对数据库安全性的需求,对三层体系结构进行改造,使其能够根据业务情况实现自动适应.同时介绍了其系统结构和特点并阐述了使用的关键技术.此系统已经应用于浙江银通的“消费即时通”业务.

Research and Appliance of the Flexible Three-tier Architecture

With the development of internet and software development structure,B/S architecture has become popular for it has more openness and is extensible than the C/S architecture,and it implements the "thin customer" module.There are many ways to implement the B/S architecture.The paper brings out an alteration to the traditional three-tier software architecture according to the need of our client with more flexibility and safety.The paper introduces the structure and specialty of the system and the key technique it used.This System has been applied to the "immediately notice when consumed" business.
