Research On Integrated Information Service System Based On Web Technology

Web is an information technology that has being in most wide use and is promising attribute to its availability and practicality. Formerly, Web was a technology only supporting static HTML page, but now it is a tool to present global information resource, carry out cooperation and business activities. On the basis of Web technology, integrated information service system gradually developed, and now has became a strongly tool to improve integrated management and competition ability of enterprise.Firstly, this paper described the concept of the Integrated Information Service System, the creation and development of Internet and Web, and the technology in common use of Web programming. Secondly, the paper discussed the key technology of Web database system and system realization, and deeply studied the middleware technology. As an emphasis, this paper introduced the concept, work theory, categories and system infrastructure of middleware, point out the shortcoming of current database middleware, and brought forward a solution to solve the problem. Lastly, making use of JSP, middleware and Web database technology, the author designed and realized the Graduate Integrated Information Service System based on B/S/S three-layer frame. By the use of middleware, this system improved its programming efficiency and code reusability, reduced the workload of code maintenance. The access efficiency of database was improved because of the use of DB Connection Pool, and the Web Service quality was improved through the combination of Tomcat and Apache. In addition, the security of system was enhanced from OS, DB Server and application system. Several months' practical use proved that the system completely meets the demand in the practice.
