Data storage method of power distribution GIS based on Oracle Spatial

NIE Du,LI Xiao-ming,TIAN Xue,XIA Jun-feng (School of Electrical Engineering,Wuhan University,Wuhan 430072,China)  
Aiming at the data inconsistency and low access rate in data storage of PDGIS(Power Distribution Geographic Information System),a data storage method based on Oracle Spatial is proposed. Compared with current major methods of data storage,the advantage in spatial data storage of the ORDB (Object Relational DataBase) is presented. The principle of GIS spatial data storage with Oracle Spatial is analyzed with an application example. Its program is written in Java,importing some open source codes designed for GIS applications. The result shows that the data storage method adopted in the example realizes the integrative storage of attribute data and spatial data of PDGIS.
