摘　　要：阐述应用程序开发的三层结构的基本组织形式及存在的问题,提出了基于四层结构的应用程序开发模型及其带来的好处。结合七里村采油厂综合信息系统开发实例,对基于.NET的四层结构的应用程序开发技术进行了研究,实现了基于.NET的四层结构的部署,阐述了基于四层结构的具体实现策略,并在此基础上给出了基于四层结构的应用程序设计与开发的关键技术。The basic organizations and the existing problems of three-tier structure of application program development are presented, and application program development model based on four-tier structure as well as its advantages are put forward. Combing the comprehensive information systems development of oil production factory of Qi Li-cun, application program development technologies of fourtier structure based on .NET are studied. The arrangements of four-tier structure based on .NET are implemented and its concrete implementing tactics are discussed, meanwhile, application program model of basing on four-tier structure and the key technologies of developing are given.
