Development Of Tectonically Deformed Coal And Its Influencing Factors Database System

The widely research of tectonically deformed coal will involve large of multisource information, and will need a variety of technical means, these things all need support of basic data platform. The building of Development of tectonically deformed coal and its influencing factors database system, not only can realize the data kept、update properly, but also can provide standard data support for multiple technologies merged, and the realization of the system analysis module can provide the primary support for the user’s analysis and decision.Combined with Lu Ling data, I maked overall design and design, build the database after detailed requirement analysis. The research of tectonically deformed coal will produce a lot of graphics data and attribute data, however the storage of graphic data cannot simply rely on two dimensional table, so this system adopt geodatabase. The development of this system adopt object oriented languge- C sharp、combine with Com GIS development tool- Arc Engine, and make use of SQL Server to storage graphics data and attribute data, and lastly make use of Arc SDE, ADO.NET for keeping in touch with data. After designing the database of tectonically deformed coal and its influencing factors, I make spatial data and attribute data entried the database, biulded the database. Lastly, started system development, I has realized the database connection, data query, data update, data analysis, data output, system security management and so on six function modules. The data query and data update all include two ways, based on graphic and attribute. The data analysis include special analysis and statistical analysis. The data output include map output and report output. The system security management include login verify, user management, and backup and recovery. The establishment of this system provide a platform for managing data efficiently and sharing information, and it is also a foreshadowing of a deeper research.
