【摘要】：民航空管有效文件检索系统是作者在多年民航空管基层工作实践中认为有必要建立的一个新的检索系统。在现有检索系统中存在不足,原因有三个方面:一是数据量大,数据源复杂;二是数据来源途径复杂,格式不统一;三是检索无统一平台,查询效率低。论文作者正是基于以上原因进行了系统的设计和开发。在相关技术中采用了Visual C#2010作为开发工具,使用Microsoft SQL Server 2008作为后台数据库支持,并对系统中用到的检索技术进行了阐述。在系统需求分析过程中,对数据的来源进行了详细描述,确定了系统的主要功能模块。分为登录模块、用户模块、数据录入模块、分类检索模块、打印管理模块和系统管理模块。在系统设计过程中,确定了系统的逻辑结构、进行了数据库的设计、绘制了系统流程图,以及对系统主窗口进行了设计。在系统功能实现中,使用ADO.NET访问SQL Server数据库;进行了公共类的设计,给出了核心代码;对六个模块分别进行设计和实现,并给出了相应的运行结果图。本系统初步实现了所预期的查询功能,但作者也认识到系统还有可以继续完善拓展的空间,需要进一步的研究。
[Abstract]:The effective document retrieval system of civil aviation air traffic control is a new retrieval system which the author considers necessary in the practice of civil aviation air traffic control for many years. In the existing retrieval system, there are three reasons: first, the data volume is large, the data source is complex; the second is the data source way is complex, the format is not uniform; third, there is no unified retrieval platform, and the query efficiency is low. Based on the above reasons, the author designs and develops the system. Visual C#2010 is used as the development tool and Microsoft SQL Server 2008 is used as the backstage database support. The retrieval technology used in the system is described. In the process of system requirement analysis, the source of data is described in detail, and the main function module of the system is determined. It is divided into login module, user module, data input module, classified retrieval module, print management module and system management module. In the process of system design, the logical structure of the system is determined, the database is designed, the flow chart of the system is drawn, and the main window of the system is designed. In the realization of the system function, ADO.NET is used to access the SQL Server database; the common class is designed and the core code is given; the six modules are designed and implemented, and the corresponding running result diagram is given. The system initially realized the expected query function, but the author also realized that there is room for further improvement and expansion of the system, which needs further research.
