Design And Realization Of Vehicle Sale System Base On C#.NET Technology

With the development of information technology networks, with the automobile market competition increasing, the implementation of information-based marketing management will be imperative. Car sales also as a commodity is experiencing paperless and network leap. Web-based network marketing system has become an important application of the Internet, the direction of research on this great theoretical and practical significanceThe author of a number of goods through the car sales company needs and the status of research and analysis. Proceeding from the actual research and development of a network of car sales system for the flow of goods vehicle sales networks, and information, standardization, and automation. Car sales increased commodity sector efficiency, the principal tasks embodied in the following points:1. C / S and B / S mixed architecture established: through existing C / S and B / S systematically analyzed and compared and found that the traditional C / S architecture is not without merit, and the emerging B / S structure is not perfect. while the system is the need to meet sales companies in the LAN and WAN at the same time dealers in the use of the characteristics used in the development of the C / S and B / S mixed structure. Using C / S development of a data structure of relative stability, and to maintain the low frequency of client software, using B / S development of a data update faster, less data server software. To achieve an organic combination of the two and comprehensively made some useful attempts.2. Service-Oriented Architecture Design and Development: in the design process in an independent functional units outside entities for public services interface, guarantee its independence and reusability, in the business logic to achieve still use the traditional object-oriented approach. Through multiple iteration can be achieved, the opening up of large particles services, business logic implementation of the small particles. To achieve system to a number of existing systems and data interface, such as production system, the tax system, financial system, dealers internal management systems. Sales of business process changes are relatively frequent, the software requirements of scalability and flexibility also needs to adapt, we need to structure the system to a more flexible technology.3. The use of technology CA certificate: As the system uses a three-tier Internet-based technology architecture, while the sales of user data security is essential. So the system through the use of CA technology for network authentication, the user must use the certificate system login to ensure that the identity of the user landing, while transmission of data through encryption technology in the network transmission, the safety of the use of data provided a powerful guarantee.4. To achieve flexible management competence: through flexible business nodes mandate, the members of each organization completed on the role of processing. Through flexible data sets mandated to ensure that each user is only able to authorized data processing and inquiries, not by leaps and bounds authority. The adoption of the flexible rights management will be able to meet with the sales organization system of continuous adjustment and the constant changes in personnel changes.5. Plans to establish sub-goods model: Achieving demand for the system, according to production capacity and sales plans through the calculated production plan in principle during which a commodity which can supply the amount of time when the shortage of goods to customers with the evaluation to determine the time and supply of commodities volume. Customer evaluation of the performance of their market plans and the accuracy rate, as a standard evaluation criteria and score their points and then a percentile rating, in the allocation of resources according to their levels.6. Achieve automatic processing of sales orders: Timing is divided into two kinds of computing and real-time calculation algorithm, is the first major distributors demand based on plans and funds available funds and, in conjunction with the company's inventory resources, shipped distance shipped capacity, historical sales data to calculate dealer orders this production Commodities Score, in accordance with the decision of how many points the order shipped, shipped locations, such as the way shipped complete process.The design of network sales of goods vehicles and transport management systems, formal development of the automobile market is Internet technology and computer technology in the field of commodities car sales application, which will now auto network sales to provide a good solution. The system uses the C / S and B / S mixed structure, and development tools to choose Microsoft's C #. Net language, the software services using factory structure, selected ORACLE9I as a background database. The main thesis on systems analysis, design and development of the entire process, using the data flow graph, the program flow chart of the system, such as the design process that detailed analysis of the system's architecture, work methods, the major functional modules, the key data work flow, background database design, a few According to the configuration and connection, the system functional modules detailed design, development and its key technology, the security of the system were studied. A network of dealers in the plan-making, orders for maintenance, logistics or vehicles, vehicle retailing, the company plans end audit, tabulated, order processing, receivables, invoicing, and other functions, the main basis of data management module, program management module, Order Management modules.
