Design And Implementation Of Maintenance And Automatic Generation Of Standard Class Library System Of Traffic Information Data Element

Transportation information basis data element standard library constructed and fullyutilized has important significance to play a role in the management of traffic informationresources, improve the work efficiency, strengthen the decision-making ability andstandardize data element standards. Therefore, in this paper, a system is designed to maintaintransportation information basis data element standard library and automatically generatetransportation information data element class library based on the hierarchical structure. Thusit makes the standard library convenient to be maintained and it makes the data elementinformation convenient to be used by programmers. Mainly completed work including:First, the theoretical basis and technical basis of the project are analyzed, data elementhierarchical structure and class library automatic generation theory are researched. Then thesystem is overall designed based on the software design process, the demand analysis and theoverall design of the system are mainly completed, the targets of the function andperformance that the system should have are proposed. According to the design aims,function module diagram, use case diagram and etc of the system are designed. Thenaccording to the overall design, more detailed design scheme is given, including the design ofdatabase, module classes, function processes and function interfaces. Finally, the designscheme is implemented and tested.Through the usage of this development system for many times, it is shown that thissystem can effectively maintain the data element standard library, meet the developers’ calleddemand of data element generation class, improve the work efficiency of maintenance staffsand developers. Meanwhile, also have the corresponding specification effect to the dataelement standard, promote the implementation of the transportation informationstandardization.
