Disquisition of Shooting Information Distribution System based on AJAX

Abstract

According to the bussiness requirement of Shooting Information Distribution Systems (IDS) based on sufficient investigation, the development status of similar system and relatived technology at home and abroad are analysed and studied in this paper. The bussiness workflow is analysed deeply based on the example of shooting results inquiry. Then a solution is proposed for Information Distribution System by remote inquiry. The popular B/S (Browser/Server) architecture is used in this system. It follows the software architecture of three-layer structure which includes presentation layer, business logic layer, data access layer. The ASP. NET AJAX (Asynchronous JavaScript and XML) is used as development framework. It implements the partial refresh and inquiry suggestion functions which provides much more convenience to the users. In this design, windows Server 2003 is used as the operating system and SQL Server 2005 is used as backstage database. The front interface supports IE 6. 0 and the following version. The entire design process includes requirement analysis, overall design, database design and detail design. In addition, the functions of partial refresh, inquiry suggestion, getting binary format picture from database are illustrated in detail. At last detailed test cases are designed to test the system.
