The Design And Realization Of Business Expanding System

Business expanding refers to a complicated process, that is, after checking clients'electric power consumption application, the power grid company will give their examination and finish working procedure, and then install ammeter and supply electricity for individual family. At present, most power grid companies especially some small ones, still rely on manual working, such as writing with pen, transmitting by hand, and always follow an unscientific arrangement mode. This leads to the whole process longer, involved more staff, and with lower efficiency. So to explore a new soft to realize information system management is imperative.The thesis designs a business expanding system of three layer architecture B/S mode based on the.NET terrace. What is more, in order to increase efficiency, lighten the burden of server and bring clients fluent and friendly experience, the technology of AJAX is also applied in the design of this system.With an investigation and research on the work of business expanding in an electric power bureau, this paper tries to sum up the operation requirement, analyze the operation flow and build functional model on the basis of the requirement analysis. Further based on the requirement analysis, the system is designed in detail, including the design of function module, database and architecture of the system. And the design of f database includes the design of database concept structure and the design of database logic structure. In the process of designing the architecture, the paper looks into the related technologies such as AJAX and ASP.NET AJAX, and has applied ASP.NET AJAX technology to the design of presentation layer. In the end of the paper, several functions of the business expanding system are realized, such as business processing module, part of the query and statistic module and system management module, and the business expanding system is tested.
