| Abstract: | Spatial data engine as a solving project is helpful to realize the mass spatial data's storage and management.With the expanding of GIS application,multi-user concurrent operation becomes the basic demand for spatial data engine.Including the research of spatial data model,some key issues on the system structure and multi-user concurrent control are described.The control method of lock and version are put forward in the end. |
| Keywords: | spatial data model system structure spatial data engine multi-user concurrent |
