An Approach to Geographic SQL Global Parsing under Distributed Computation Circumstance

HUANG Zhou,PENG Xia,ZHANG Ke,CHEN Bin,MA Xiu-jun,FANG Yu(Institute of RS and GIS,Peking University,Beijing 100871,China)  
Aimed at the working mechanism of GSQL(Geographic SQL) under distributed computation circumstance,an approach to GSQL global parsing was derived in this paper.Based on bringing forward the GSQL global parsing model and one new concept: EDP(Equivalence Distributed Program),the detailed flow of how to parse the global GSQL statement into an EDP file was introduced.Using this approach,one global GSQL statement could be mapped into several local statements,the generated EDP file also specifies the local statements' execution order,and so it can support the query of distributed spatial data.
