Study Of Minjiang Watershed Datasharing System Based On Smart Client

Digital watershed is a heterogeneous distributed information system,the giant data integration and information sharing is a basic requirement and technical difficulties.Due to the particularity of the basin,based on the data of fat client(C/S) and thin client(B/S) data sharing system framework of cannot satisfy the users demand,and normal smart client technology for effective combination of C/S and B/S,can adapt to the advantages of the client application and different platform environment.The minjiang river is an important branch of Yangtze river originates.In recent years,the face of minjiang river valley water resources,environment and society development,some research institutions accumulated lots of minjiang river valley about data,such as spatial data, hydrological and meteorological data,the water conservancy project data,and operational management data resources and environment,a large amount of data space,the space data from different sources and different formats of data integration and sharing becomes the focus of research.The city of minjiang river water also accelerate industrialization,the lack of original, water pollution is more and more serious,water environment is the most important part of environmental protection,water,reduce the minjiang river water environment pollution and improve,improve the urban living environment and attract more business opportunities,will help promote economic growth mode of minjiang river region,west to the reform of implementing the strategy of sustainable development.Based on the upper reaches of minjiang river water management information systems,in the.net environment,using smart client,the comprehensive use of GIS,database technology, network security,and programming techniques,which provide a unified heterogeneous data sources,efficient,reliable,sharing platform of B/S or C/S fuses in together,realized the full utilization and sharing resources,end users have connection,intelligence and ability to deploy and automatic updates.Intelligent client has Windows forms applications have friendly interface,easy to install and web program,support characteristics of intelligent deployment and automatic updates,different user can download privileges in client applications,local operation.The realization of geographic information release,browse,operation and provide spatial data offline and online processing,can maximize the use of resources and provide automatic update and seamless component installation.In future years,intelligent client will gradually get providers and users,industry will arouse an intelligent client transfer to the boom.
