【摘要】：交通信息基础数据元标准库的建设和充分利用对发挥交通信息资源在管理中的作用、提高工作效率、加强决策能力及规范数据元标准具有非常重要的意义。为此，本文提出设计出一种能够实现对交通信息基础数据元标准库进行维护及自动生成基于层级结构的交通信息数据元类库的系统，从而便于标准库的维护工作以及程序员对数据元规范的使用。主要完成的工作包括：论文首先分析了设计的理论基础及技术基础，对数据元层级结构及类库的自动生成理论进行了分析研究；其次，依据软件设计流程对系统进行了总体设计，，主要完成了系统的需求分析和总体设计，并提出系统应具备的功能与性能指标，根据设计目标设计了系统功能模块图、用例图等；然后根据总体设计给出了详细的设计方案，包括数据库的设计、各模块类的设计、各功能流程的设计以及功能界面的设计；最后对设计内容进行了实现并进行了测试。通过应用，表明本系统可以对数据元标准库进行有效的维护，满足开发人员对数据元生成类的调用需求。系统在提高了维护人员及开发人员工作效率的同时，对数据元标准也起到了相应的规范作用，促进了交通信息标准化的贯彻落实。
[Abstract]:The construction and full use of the basic data metadata standard library of traffic information is of great significance for giving full play to the role of traffic information resources in the management, improving the working efficiency, strengthening the ability of decision making and standardizing the data element standards. For this reason, this paper proposes a system that can realize the maintenance of the basic data metadata standard library of traffic information and automatically generate the class library of traffic information data element based on hierarchical structure. In order to facilitate the maintenance of the standard library and the use of data metadata by programmers. The main tasks accomplished include: Firstly, the theoretical and technical basis of the design is analyzed, and the theory of automatic generation of data element hierarchy and class library is analyzed and studied. Secondly, the overall design of the system is carried out according to the software design flow. The requirement analysis and overall design of the system are completed, and the function and performance index of the system are put forward. According to the design goal, the system function module diagram, use case diagram and so on are designed, and then the detailed design scheme is given according to the overall design. It includes the design of database, the design of each module class, the design of each function flow and the design of functional interface. Finally, the design content is implemented and tested. The application shows that the system can effectively maintain the data element standard library and meet the requirement of calling the data element generation class. The system not only improves the working efficiency of maintainers and developers, but also plays a corresponding role in standardizing the data element standard, and promotes the implementation of traffic information standardization.
