Online bidding system as a concrete situation of e-commerce, is the implementation of electronic bidding and purchasing business transformation, the entire bidding process in all aspects of the data elements to quantify the maximum possible use of computer and network for accurate quantitative data on the record , computing, communications, business to make the tender more accurate, efficient and safe.A company as the special geographical environment, traffic occlusion, under the diversity of plant mineral procurement, tender management complexity, and many other factors. In practice, how tender the management of the fair, just, effective and timely procurement of materials to their needs, and are likely to reduce procurement costs, need to design materials to establish a comprehensive management system for online bidding and purchasing, reduce company costs.A company in the past by analyzing the tender management problems, on the tender A company under the management of the factories and mines the actual research from the project, analyzes the characteristics of project requirements. A company with factories, mines and various branches of the actual situation of the system related to business processes, data and other issues the details of a detailed investigation and analysis and discussion of the requirements management process, the situation was designed for the needs of the project specifications.Through the use of the overall design, the combination of A’s online bidding system design power of attorney and project needs analysis reports, analysis and discussion systems development, operating environment, business process design system, process and structure of the system.In the third chapter of the specific design of the system are described in detail, including system level design, system, database design, system interface design three aspects. Outline design for the system, mainly from the system architecture design, network architecture design, platform design and function of structural design are described in four areas; database design for the system described the system mainly involves all the basic information form and structure. The system interface design and function, mainly from two aspects of system interfaces are described.In the fourth chapter of the system design is very important that an element of system security design are described. Mainly for computer hardware security, software security, network security, data security, respectively, were described in four areas. In the last section of this study are summarized, and put forward relevant proposals.
