The Application Of RIA Technology In The Item Bank System

With the continuous maturation and development of computer network technology, the internet applications which based on B/S had become abundant in past two years, and also they are affluent in the functions. New technologies emerged and is gradually replacing obsolete technology. As the latest technological standards, RIA (Rich Internet Application) is coming. RIA makes it easy to use client-side program as simple as to use Web on the Internet. RIA can offer a user interface with concentrated content,fast response and abundant graphics by the client engine to replace the simple HTML application, and it can make a brand-new experience for the users.With the application of computer management information system in the field of education, the Item Bank System appears, which can replace the manual to do a lot of job such as set papers, check papers and analyse papers. the Item Bank System close relationship with database, regardless of the difference between programming language that programmer uses.The paper discuss how to build a new Item Bank System. Relying on the application of RIA, the client side can become powerful by combining with Flash technology and Component technology , realize the data exchange from server to client by using PHP and XML technology, built Apache Web server and MySQL database server, generate word format papers through WordML technology. The paper briefly describes the feasibility studies, analysis, design and realization. Database design is the most important task, a rational structure will greatly improve programming efficiency and prolong the software life cycle. Many key technologies such as the Event Listener, the XML Phasing, the Special Character Converting, the Code Converting, the Central Algorithm and the Output of WordML. The paper will focus on the two parts. The system adopt the new development style and its major advantage is the fast developing of client User Interface and general XML data exchange technology. Practical application show that the system has the advantages of friendly interface, simple operation, and practical function.
