Design And Implementation Of Construction Project Bidding System Based On J2EE

Bidding in the construction project is a construction product as a commodity exchange transaction form.In the planned economy under the conditions of using pure administrative way of distribution construction tasks,the establishment and implement of construction project bidding system is a major reform measures,its purpose is to protect market competition and be against market monopoly,it is an important symbol of development of market economy.Nowadays with the rapid development of computer and network technology,the intelligent bidding management informationization construction,has become the development trend in the bidding.At present in our country,with the sustained growth of economy,the demand of the construction project is also increasing.But there are some problems in the bidding management,such as low efficiency,work tedious,resource waste,etc.Therefore,strengthen the information construction of bidding can greatly improve the level and efficiency of bidding management work,save money and human resources,at the same time to ensure fair and fair and transparent bidding work.Based on the construction project bidding information website of Shanxi Province,through investigation and research,this paper analyzes the construction projects in the bidding projects the business requirements and functional requirements.Then make full use the existing network and equipment,on the basis of system analysis,completed the detailed design of the system.Finally guided by the J2EE technology,uses the mature Struts + Spring + Hibernate open source framework,implements the user permissions management,credit archives management,bidding management and the information release,and other functions,basically completed the construction of the early stage of the bidding business requirements.In the process of the realization of the module,using the classic Java design pattern to realize the coupling between modules,facilitate late system further extensions,adopt advanced and mature technology,ensure the system has high security and stability.
