At the same time, the development of systems theory, systems and design features are introduced. With the popularization of Inter, more and more panies set up their own WWW sites, enterprises can display products through the website, publishing the latest developments, with users sharing and munication to establish contact with partners, as well as emerce. Information Management System which is an enterprise Web site an important part of it bears a double role, on the one hand, the dynamic can be used to release the new product or new development projects, on the other hand, the timely notice to their customers business performance, Progress in technology and research and development, in particular, remend or preferential projects, products and services to attract customers, expand customer base. Management of traditional news sites in two ways, one static HTML page, update the information needed to recreate the page and then upload the page and modify the corresponding links, the efficiency of this approach is too low because we have little use. The second is based on ASP and scripting languages, dynamic Web pages and databases, through the application of procedures to deal with news, this is way more popular. However, due to the limitations of ASP allows the system itself, there are some insurmountable flaws, and technology has taken on the system performance has been greatly improved, the main performance in the following aspects: 1. ASP page to open as a result of each must be piled to explain the process, so when the page opens in the rate of repeated there is no upgrade, and only need a page do not need to repile piled until the page has been modified or Web Application process restarted. This makes the speed in a number of visits has greatly improved. 2. As the ASP does not provide any output data for the content of the ponents, so writing a database using ASP page can use the Record Set Object ADO to read records of transaction, while the ASP provided through the DataGrid, such as database and database ponents can be directly Contact. 3. ASP support realtime application updates. Administrators do not have to turn off the work server or even do not have to stop running the application can update the application on file. Application documents will never be locked, so even when the program runs in the paper can be overwritten. When the document is updated, the system will convert to the new moderate version. 4. ASP take the codebehind approach to the preparation of the code makes the code easier to prepare, structure more clearly, reducing the system development and maintenance of the plexity and the cost of. 1 System Development Principle The System Architecture Model of ASPbased Technology ASP is a threetier system structure: UI Layer, Business Logic Tier and data layer. UI layer is responsible
