The Reserching And Realization Of Three Layers WEB APPLICATION Based On DOT NET

With the rapid advancement and deployment of Internet,distributed systems and web applications play an important rolein computer science nowadays. The most widely deployed Webapplication architecture is the B/S system, which is composed ofa browser, a front-end Web server, an application server and abackend database. So developing a dynamic Web application is asystemic task, which needs comprehensive analysis and design fromthe aspect of network, architecture and database.The content of the paper takes raising software function andmaking software maintenance easily as point of departure, designsa three layers design pattern of web application based on dot net.Firstly, understand the principle and characteristics of Web,have a thorough research in two famed design pattern and combinedtwo pattern according to their characteristics in to lengthwaysdesign mode. Secondly, invent a horizontal produce-consumepattern according to the strong alternant characteristics of Web.Thirdly a test-bed is built to measure model parameters calledexam-managing of self-educated examine office of Jilin province.Lastly, give some attitude on security about our design pattern.
