Based On B / S Structure Of Vanadium-titanium-line Trading System Design And Implementation

The B/S architecture of application comprises three layers and become a standard application mode. While the client is replaced with a browser, the server consists of web server, database server and middleware. The browser connects physically to the server through Internet/Intranet and obtains services from the server through URL based on the HTTP protocol. With the development of Internet applications and technologies, enterprises gradually adopt this application architecture to build their own application systems in order to combine them better into Internet/Intranet.The dissertation is devoted to present the state of research on and the developing trend of the application system in domestic or overseas enterprises. Focusing on the actual application, we develop a on-line vanadium and titanium trading system based on Internet / intranet technology, such as the B/S mode, ASP and Web language, etc which make the on-line system can be used in wide application areas. This system comprises a series of process management by means of computer network and flow, such as regarding the enquiry, the quotation, contract, execution of the contract, the stock management, the approval of the bill, custom clearance, the transportation, the financial management of PIETC import and export business. This improves the enterprise management level as well as work efficiency and strengthens the trading safety.The structure of the dissertation is as following:ChapterⅠintroduces the developing background,goal and significance of the system. ChapterⅡanalyzes the demand of the customer, and constructs the data flow chart of the business and the data dictionary. ChapterⅢestablishes system model and designs the general functions of the system. ChapterⅣdesigns the data base and the configuration of the data mode. ChapterⅤintroduces the design of the application software and the interface, the development and the realization of the process. ChapterⅥintroduces the combination technology between system and browser, and expresses the developing thought of working flow,and offers the characterization interface etc.
