SYSTEM AND METHOD FOR SYNCHRONIZING SPATIAL DATA BETWEEN DIFFERENT SPATIAL DATABASES

摘要

PURPOSE: the geographic information data of synchronous system is stored in the effective of different product in the data that different types of spatial database provides a kind of geographical information space database synchronization. ;CONSTITUTION: changing the substance that senses of sensing module, and the synchronous target platform of change in the substance about record is more than the spatial database in a source. The substance sensing module record of change has the substance table of the substance change changed about the information of record. The item of the synchronous variation of first sync agent (106) is recorded in the fixed cycle for changing object table to the middle storage room of spatial database, then stores the substance of change. The substance of the second sync agent (110) synchronous change is stored in the middle storage room of spatial database, then stores the substance of change, according to the synchronous request message that receives from the first sync agent. ;The 2013 of copyright KIPO submissions;[Reference numerals] (102) source place DB; (104) middle storage places DB; (106) sync agent first; (108) destination place DB; (110) second sync agents; (112) information management agent
