The Application of Data Warehouse Technology and Function Warehouse Technology in the Hydrological

摘要

GIS technology has already used in the Hydrological forecast and forecasting. But because various GIS software has different formats and unattached functions, people can not use them conveniently, and the data and functions sharing can not be achieved. So it brought great inconvenience in GIS technology using in the hydrology of the general industry. In order to solve this problem, researchers bring method which use Data Warehouse technology and Service-oriented Architecture (SOA)of Functions Warehouse based on GIS technology to solve it. In the paper researchers describe how to use Data Warehouse to achieve multi-source heterogeneous data storage and how to use Function Warehouse to achieve the integration and sharing of variety of heterogeneous functions; the analysis focus on explaining the technology of the Data Warehouse using the middleware to achieve storage operations of the heterogeneous data, and the model of Functions Warehouse, and the mode of the Function Warehouse construct and manage the various functions. Through the use of Data Warehouse and Function Warehouse, we can solve how to storage multi-source heterogeneous data of hydrology, and how to achieve the hydrological forecasting and hydrological problems in multi-share. It can bring a new method to let applications of GIS technology in hydrology industry more convenient.
