In this paper, the authors defined, at first, the intention of the problem, and then related their design to the structure, data updating mode, data consistency of Multiple Representation Database. Finally, some application examples of MRMD were described, including multi scale displaying of electronic maps, spatial hierarchical reasoning for geographic objects.
