| This paper mainly introduces the research background of people’s mediation system, and summarizes the questions which should be solved by the system. At the same time, this paper elaborates the importance and signification of system research.This paper discusses four points overall:Firstly, it briefly introduces some backgrounds, thoughts and original intentions of people’s mediation system, analyzing the questions which should be discussed and solved, discussing the project’s signification and influences, the detailed description of system’s mainly development methods and related technical theory knowledge during the development of system. Secondly, this paper raised system’s primary design goals and ideas. It takes a simple demand analysis plan and includes business requirements analysis, functional requirements analysis, data demand analysis and the analysis of the non-functional requirements. Besides, this paper depicts the systemic business process diagram, data flow diagram, functional data analysis diagram (IPO diagram) and describes the data dictionary. Then, during the whole design processing of people’s mediation system, it gives a overall design and module design. Accordingly, it provides the total function structure diagram (H diagram). It includes some function module such as basic data management, statistical analysis, hair replacement applications and so on. With this, it is given, functional structure design module (H), IPO, and process flow chart. The contents of design are totally described in detail by those functional module and several kinds of functional structure diagram. On the basis of it, using entity relationship between E-R diagram and database table to design database minutely. At last, this paper summarizes and rethinks the contents of this research, except state my own job contents, it also points out paper’s defects and needs to be strengthened. And it also gives more clearly planning and encourage to my future work. |
