User GroupsDatabase users can be grouped into user groups.
A user group can either be assigned to thedatabase user class RESOURCE or to the database user class STANDARD. Database users can be defined as members of a user group.
All database objects defined by members of a certain user group can be identified by the user group name. The owner of objects such as these is the user group and not the individual user that defined the objects. If a member of a user group creates objects, each member of that group can work with these objects as if they were the object owners.
Privileges can only be granted or removed from the user group as a whole and not from individual members of the group.
