Design and Implementation of GSQL

LI Xun1,FAN Cheng-xiao2,XU Hui-ning2(1.Xi'an Technical Division of Surveying and Mapping,Xi'an 710054,China;2.61363 Troops,Xi'an 710054,China)  
The simple relational database with object-oriented model can not meet the application requirements of the user data management.Therefore,the object-oriented relational database came into being.Meanwhile,in order to query and manage spatial database efficiently,the geometric structured query language(GSQL) was produced.What this article carried out is mainly the preliminary exploration of the spatial query language.Also it elaborates in expansion of the OpenGIS vector data model GSQL language,including spatial data types created in the Oracle,spatial functions,methods,and detailed examples.
