利用Delphi开发基于COM+的多层分布式应用

Developing distributed application of multiple-tiers structure based on COM+ technique by Delphi

介绍了Windows2000DNA的体系结构,讨论了COM 的系统架构、服务和多层分布式系统结构模型。以学生管理系统为应用实例,提出了利用Delphi开发COM 多层分布式应用的方法。阐述了系统中应用服务器、后台数据模块及客户端的开发实现过程。实际运行结果表明了该方法的实用性。

The architecture of windows 2000 DNA was introduced,and the system structure and services of COM+ and multi-tiers distributed system model was discussed.Taking the student management system as an example,a method was proposed based on COM+ distributed application developed with Delphi.At last the system implementation and development process of the application server,data modal and client was addressed in detail.The running of the application proved that the method is practicable.
