| Along with the information age and the market economy gradual establishment, the statistical data is playing more and more vital role in various aspects of national economy. Statistical unit quantity increases unceasingly, the society increases unceasingly to the statistical information demand. In such situation, the primitive paper report form and manual collection data's method already by far could not satisfy the current statistical work in the actual need, moreover,the single data processing software of all forms also has caused difficulty in the data 's sharing, storage and the analysis. Therefore, it's an important topic which the current statistical work facing is developing a all-purpose, based on the network and the data bank technology, take the scientific standard system of statistical indicators and the classified standard as the foundation, the reflection statistical work standard flow statistical service synthesis processing system. Enhances the gathering, the transmission, the storage and the handling ability of information by using the modern information technology.Based on this demand, this article first analysed the current statistics operation flow and the reailze in the software platform, and based on the analysis, designed and develops a set of software system to use in statisitcl department specially and conformed to the statistical work method. This system's design process has used the object-oriented software engineering development technology. From the requirements elicitation, analysis, the system design to realize finally, uses the project technology thought fully the superiority, through the modeling solve system's complexity, uses the object-oriented design method to achieve code reuse, and has used Web in the deployment phase the Service three architectures, has realized system's cross platform correspondence as well as the level and the level loose coupling.During the design process, this article uses UML (unification modelling language) for system development modeling and visualization methods of preparation of documentation, guidance and implementation of the system. Through needs analysis, analyse of the current problems and needs, summarizes the functional requirements and non-functional requirements and the use of UML use case diagram, class diagram and sequence of the overall picture shows the system modeling. Part in the system design, analysis of the system design objectives and principles set up a system of overall planning, technical architecture, functional architecture and database design. At the detailed design of the Report of this article focus on the core system management subsystem used in the detailed design process and methods are described. And at the last part of the implementation of the system design of the Special Report and formulas are two key issues in system implementation are described.The design of the system has used the thought of the statistical metadata management. That is an open comprehesive stastic bussiness application platform witch contains data collection,data processing and secure storage for implementation of the system described in the majority of bussiness features and rich formula edit function, and this basic platform as the support for the application of data warehousing, data mining technology, other applications such as statistical analysis provides a powerful data engine. |
