Multiuser Geodatabase
Multiuser geodatabases leverage ArcSDE technology* implemented on a relational database management system (RDBMS) platform to
- Provide organizations with a central, scalable data storage and management system.
- Utilize additional functionality that is not available in single-user geodatabases.
- Provide better data security (such as access permission control for individual datasets), backup, and recovery.
- Maintain data integrity with features such as data backup and recovery, rollback, and failover.
- Monitor your geodatabase performance with the free Geodatabase Toolset (GDBT).
There are three types of multiuser geodatabase: enterprise, workgroup, and desktop.

* Note: Prior to ArcGIS 9.2, ArcSDE was a stand-alone software product. At the ArcGIS 9.2 release, ArcSDE was integrated into both ArcGIS Desktop and ArcGIS Server. ArcSDE technology manages spatial data in an RDBMS and enables it to be accessed by ArcGIS clients.
