The Design And Implementation Of Network Bidding System

Bidding technology relates to the economic lifeline of many enterprises and plays an important role in the development of company. In recent years, with development of Web2.0, the existing problems of traditional bidding technology are becoming more and more obvious. Consequently, the design and implement of network bidding system has a very important actual significance. Network bidding system apply network and information technology methods to the developing and design of the system. It transplant the whole flow of bidding to network and associate the bidder, tender, bid evaluator by some ways. It has solved the problems of traditional bidding way in tedious procedure and high cost. It makes the whole bidding procedure more easy and quick.The Web applications based on three-layer B/S framework is very popular among the current developing of the Web design. According to the software design principle of "High cohesion, Low coupling", it divides the whole business application into UI, BLL and DAL. Framework technology is a very important software technology in J2EE. We can reduce software development cost and improve software development efficiency through applying framework technology. And it is helpful to expansion of the system in the future and can make the every layer interact each other in a low coupling way in order to easy system maintenance.In this paper, we employ the MVC design pattern to divide the Web application into three layers and apply three open source framework, Struts, Spring, Hibernate (SSH) to complete the function of each layer. We develop a bidding system based on SSH framework. In this system, we make full use of the advantages of Struts, Spring and Hibernate and reduce the cost of developing. The system has a lower coupling, high system scalability. This is more helpful to the sustainable of the system.
