基于WEB的分布式计算机结构及应用技术研究
摘要
随着国际互联网的高速发展，基于Web的分布式计算结构由于其自身的众多优点得到了日益广泛的应用。与此同时，目前基于B／S结构的开发技术还存在许多不尽人意的地方。本文针对当前B／S结构中存在的问题，提出了一种构建分布式应用系统的 Web应用程序框架。由于分布式数据访问是Web应用程序框架实现中的关键技术问题，本文重点对分布式数据访问技术进行了研究，采用了基于中间件的解决方案，并在对分布式数据访问中间件的研究和实现过程中，提出了用脚本语言来编写业务逻辑的思想。最后，详细描述了Web应用程序框架的实现模型，并简要介绍了它在南京禄口国际机场生产运营管理信息系统中的应用。
With the rapid development of Internet, the architecture of distributed computing based on Web becomes more and more widly used due to its own merits. And meanwhile, current development technologies on the B/S architecture does not work perfectly as we need. This article brings forward a Web application framework for building distributed application systems which is designed to solve problems exists in today's B/S based systems. As distributed data accessing is the key problem in realizing the Web application framework, this article gives a resolvent which assumes the technology of middleware. It also puts forward an ideal of writting business logic which uses scripting language in the discussing of distributed data accessing midlleware and its implementation. At last, this article detaily describes a realized model of Web application framework and briefly introduce its application in Information System of NanJing Lukou International Airport.
