# System Database

JMap has a System database that contains JMap Server’s configurations and geometry tables. This database is mandatory and generally should not be modified. It cannot be deleted and should only be manipulated by advanced users. See section [JMap Server System Database](/en2/administrator/jmap-server-administrator-manual/jmap-server-management/jmap-server-system-database.md) for more information.
