Web GIS System Integration Development Based On Visual Studio.net & The Distributed Database

GIS based on C/S and B/S framework has the broad application prospects.Through the real Web GIS systematic development based on COM,C/S & B/S and the exploration to the application of the more technology,this pater is achieved.In this paper, the following achievement is getted:(1) Through the real systematic development and the exploration to the application of the distributed database and MapObjects and Visual Studio, it is suggested to the solution and the key technology in the systematic integration development of GIS, related the GIS data with the remote database, realizing the data increasing, deleting, changing etc. This System is not only the normal GIS system, but also real the distributed database Client/Server & Browse/Server system.(2) Through the real GIS development and the exploration to the application of the distributed database and MapObjects and Visual Studio.NET, it is suggested to the advanced solution and the key technology in the systematic integration development of GIS, related the GIS data with the remote database, realizing the data processing.(3) Through the Web GIS development based on B/S and the exploration to the application of ArcGIS Server and Visual Studio.NET, it is suggested to the solution and the key technology in the systematic integration development of GIS based on B/S framework.(4) Through the GIS development and the exploration to the application of Visual Studio.NET and Visual Studio 6, we compare the performance of the technology between VB.NET and VB 6 in the systematic integration development of GIS.
