On Comgis In The Distribution Of Oil And Gas Resources And Exploration Of Spatial Database Research And Applications

Base on our experience, in according to ComGIS, the thesis discusses in detail the design and development of Spatial Database Management System for the Distribution of ChangQing Oil Gas Resources and the Surveying Work, and expatiates on the application of the system. The main content in the thesis includes:1.It sums up and analyzes the concept of GIS/ComGIS and realization form and system frame of ComGIS.2. ESRI ArcViewGIS, MapObjects2.0 component object technology and Shapefile, as well as relational database are analyzed briefly according to user' s requirements analysis. Also, the development method is presented.3. The thesis introduces instance of the Distribution of ChangQing Oil Gas Resources and the Surveying Work and discusses the choice of the softward platform , analysis of the system structure and characteristics of system development.It also points out the development direction.4. Via analysis of the main functions of the system, the design of spatial database are discussed in detial.5. The thesis discusses the process of system development with MapObjects2. 0 component object technology and interface technology via programming, besides studies the key technologies and solutions during system development.
