When spatial objects are replicated at several sites in the network, the updates of a long transaction in a specific site should be propagated to the other sites for maintaining the consistency of replicated ...
If any two or more transactions at different sites concurrently update some spatial objects within a given region, two spatial objects having spatial relationships should be cooperatively updated even ...
Implementation For building the replicated spatial database, we have decided to use an object-oriented spatial database system, called 'Gothic 3.0' [14] , being operated on two workstations (HP C200 and ...
