| Abstract: | The authors firstly discuss several specific questions on the importance, updatability and shareability of GIS data. The data management system and data altering mechanism of a real-estate bureau in a big city in China are especially introduced with the emphasis on the data updatability. Meanwhile, the problem of data updating and maintaining existed in the system development is explored. The concurrent operation on the long transaction in the data management mechanism is elaborated. A number of real cases are introduced to aid the depiction of problems and solutions. |
