The Design And Realization Of The Multilayered Distributional Architecture In Enterprise Application Based On .NET

This article has done certain research to the system architecture historical development and evolution. Briefly introduced the application software system structure, from the traditional customer/server two architectures continuously to take the browser/server as representative's three modular designs, simultaneously had pointed out the insufficiency and the flaw in the traditional construction. Take its superiority, and has designed the multilayered architecture of Caiyingtong system based on .Net.The object-oriented design thought has been dissected in the software development. The valuable analysis and realization in effectively has been applied the object-oriented design pattern in the system development. Carries on the comprehensive analysis to the Microsoft NET platform technology, unified the Web characteristic to make the concrete analysis to the concrete development technology, and specially has conducted the massive research to ASP.NET and ADO.NET technology, and fully embody in the system design and realization. Understood the security knowledge about the web system, and the full application has reflected in the safe defense of Caiyingtong system.The development of Caiyingtong system is the demonstration of the multilayered distributional architecture system base on .NET, has applied the network programming and the object-oriented development design method, is a multilayered system architecture example based on the Web, has supplied a usable mode for developed the multilayered distributional architecture system base on .NET. The article elaborated with emphasis how this system is analyzes from the understanding customer demand to the concrete function code realization complete process, the system structural is designed five layers, respectively is the User Interface Layer, the Business Entity Layer, the Business logic Layer, the Business Facade Layer, the Data Access Layer. In detail describes a general distributional multilayered architecture concrete design procedure, and in detail elaborated each realization detail, has provided the very good study reference.The research and implementation of the system fully showed that the Microsoft.NET had the very strong superiority in small and medium-sized enterprise's application system development aspect.
