The Design And Implementation Of Provincial Basic Hydrology Database

Hydrological data base is the country’s economic construction and social development in hydrology for the social and economic, environmental, ecological and traffic information products and services is an important strategic resource, basic information, but also the source of all water-related decision-making activities. Basic hydrological data and hydrological data in most species, the largest and highest quality data, and the data type is from generation to generation, the Earth hydrosphere is the most authentic performance in hydrological data base of the most complete record of the Earth’s water circle and people living in accordance with the transformation of the environment. Hydrological database includes and is closely related to the use of some convergence of data, from actual survey data to monthly statistics, including precipitation and evaporation, and ice flow, tide and water, sediment and water and other statistical characteristic values, including connection and data flow instructions and methods of information distribution stations, station property and calibration information, information, and data reliability information section, all of the hydrological analysis can be combined with the water conservancy hydrological data and build a data base for the realization of hydraulic calculation and mechanical calculations. So the basic hydrological database construction is an important hydrological transport wiki this business.Hydrological database construction depends on the hydrology of business needs and IT technology and economic and social development and progress, is a complex system engineering, the construction is a dynamic process of development. As a modern hydrological database construction, solve for the solution of economic and social services on the basis of hydrological database construction and application service problems in imperative. This will Base on the review of the development status of the domestic and international basic hydrological database, make full use of the basic hydrological database table structure, the J2EE platform and thetypical J2EE multilayer system structure, storing surface water BGF data, photos, results, hydrology and water resources survey results, telemetry data, engineering station operation condition of the whole sequence data and the corresponding method of information and information network. A Provincial Hydrological Database will be designed and implemented, to support the hydrological information services to meet the multi-scale, multi-level, multi-mode hydrology dynamic information needs.
