The Distributed Management And Application Of Easymap's Data

《Drawing Digital Figure and Administrating System of Mine (EasyMap)》 is an important project of ShanXi Province in "The Tenth Plan of Five Years" period. It is a computer software system including of drawing and administrating mine digital figure .It can draw landform figure, geological figure, landform and geological figure, excavate preject's flat figure and mine well's up and down contrast figure. Now, this software apply in an alone computer. For tracing the Internet technology's development, we need administrate its figure data by distributing way.Using the database technology to realize the EasyMap's data in the network, and extending this software's using area, it is the task in this thesis.We study the conception ,the feature and the management ofthe spatial data, and discuss the management technology of the distributed spatial data for some extent in this thesis. We additionally found an database management system for EasyMap' data about client/server mode. The database system in this thesis used the new technique of visiting database whose name was ADO, and the database management system whose name was SQL server 2000. We searched and designed the content, also fulfilled it by writing program. This content included founding the spatial database, saving the EasyMap' figure document in it as the dot, the line, the text and the sign, visiting it and reading its data one by one and applying the data from the client.
