Enterprise geodatabase support
ArcGIS Server includes capabilities for managing multiuser geodatabases in a number of DBMSs (including IBM, DB2, Informix, Oracle, PostgreSQL, and SQL Server), including the ability to support a number of critical version-based GIS workflows. The ability to leverage your organization's enterprise relational database is a key advantage.
