Design And Implementation Of Sichuan Daily Bidding Screening System

Based on the requirements of bidding development, Sichuan Daily Bidding and Selection Netword Technology Co.,Ltd., as the organization established the team to develop the bidding screening system software, providing information management platform for the project construction bidding of Sichuan. Sichuan Daily Bidding and Selection Network Technology Co.,Ltd., which one of duty is providing information management platform based on the WEB framework for the Sichuan biding management department. Meanwhile the company also give the assistance in technology and management to the department.Sichuan Daily bidding screening system uses B/S framework that is popular at the moment. In the process of the design and development of bidding screening system involved theory and technique are:based on object-oriented component development theory? theory of data mining?information search and WEB server framework design. In the specific development, Sichuan Daily bidding screening system uses the development portfolio with Apache?PHP and Mysql, and also integrate many popular open source frameworks.The paper described the development background of bidding screening system and determined the the basic development idea of the present system at the first time. Then, the paper described the common technologies and characteristics of development methods of current information systems development, like WEB. According to the communication with the user, the system find out the functions and business processes in detail. According to the needs analysis, the paper confirmed the software framework of the system and goal of software development. On the basis of the needs analysis, the paper has described the overall functional framework design and database design of project management system, and introduced the detailed design and achievement of each functional module.In the process of the analysis?design and development of this system, developer with the help of a number of software which UML provided for to analysis and design. There formed a standard system analysis and design documentation. Especially with the help of UML, the developer build the database model of the system, and then clearly confirmed the data table framework of system. In the detailed design and implementation of the system, the paper still used the function package provided by UML tools to make the refined design of main core business functions of research management systems. In the detailed design of the content, the paper illustrate the sub-function package design corresponding implementation of mainly function in the system, and described the main work and business process of system.The system has been system testing during the process of development and after the development, the test results show that the system basically meet the design requirements.
