This paper presents a “versioned” managing mode to manage the geological database, and a model of version management based on DBMS. The design process and architecture are discussed, as well as the main arithmetic and technologies of version realization in MAPGIS 7.0. It solves the concurrency control problem of long-duration transaction which cannot be solved by traditional GIS software. Test shows that in actual application, users can do cooperative editing for a long term with MAPGIS7.0. Now it has been successfully applied to the national geological survey spatial database management system.
