摘要：In this paper, two cases of data consistency problems are discussed in Multi-user Geographical Information System. When a user updates some spatial data that have been accessed by other users in database, or executes an UNDO/REDO operation, data consistency will probably be destroyed. To solve the problem caused by the first case, a “Notification-Reread Method” is introduced. As for the second case, there are many problems to be studied.
