软件系统的分层设计

摘要

The concept and principle of layered design method for developing software system are presented in this paper. The layered architecture recommends are given respectively for the applications based on Client/Server model,Distributed Computing model and Web Database model. The advantages and disadvantages of layered design are also analyzed. At last,an application example designed by layered architecture is given to illustrate its efficiency.%文章提出了软件系统的分层设计概念及其思想原则，并为基于客户机/服务器形式的应用、基于分布计算的应用和Web数据库的应用给出了分层结构建议，还分析了分层设计的优缺点。最后，给出了一个实际应用例子，以说明分层设计的有效性。
