The Development and Application of Safety Monitoring Data Query System of Sanmenxia Dam

摘要

For being incapable of interoperability of some special data file structures, the rele-vant source program must be modified when the data file structures change. This data query system exploited by the writers of this paper, has high-level intelligence. It can open directly and automatically to analyze and identify different types of files such as SQL Server database,Access database, Excel spreadsheet and text file, and it can search name, type, format and value range of data items. Users only need to enter the name of data file when they do some query instead of the details of data file structures. The system can be used to solve the prob-lem of interdependence in query system and data file structure, and realize the unification of different data file manipulation platforms. It's very useful in monitoring data integration op-eration in Sanmenxia dam.
