摘要
指出了软件开发过程中传统两层C/S结构存在的不足,提出了基于CORBA的三层分布式结构,在Delphi环境下完成了CORBA中间件模型。实验表明:系统中三层结构层与层之间相互独立,任何一层的改变不影响其它层功能。这种结构使得客户程序与服务器端分离,更有利于系统的维护和代码的重用。
The paper points out the disadvantages of traditional construction of 2-layer C/S,puts forward the construction of 3-layer distributed system based on CORBA,accomplished the middle model of CORBA in Delphi circumstance.The experiment finds that it＇s mutual independent of 3 layers of the system,any layer could not affect the faction of other layer.This construction separates the client pro grams from servers,that＇s better for system maintenance and code reuse.
