Wang Yan-hua · Cehui kexue · 2010
Chongqing underground river database contains a large amount of data about climate,hydrology,geology,chemistry and social economy and so forth.These data are collected from different data agencies or the result of surveys and in different formats.Spatial database designed with relational database management system(DBMS) and geographical information system(GIS) does well in storing and managing both spatial data and attribute data but the regular DBMS does not.Chongqing underground river database was developed with ArcGIS 9.2 and SQL Server 2005 Express which were linked by ArcSDE 9.2.Scientific data management can make hydrological modeling,spatial statistical analysis and water resources assessment more convenient in the future.
