A resource group category is a folder where you organize
and categorize resource groups that belong to the same product family
or business domain. Examples of resource group categories are IBM® Rational® ClearQuest® user databases that have the
same schema or IBM Rational ClearCase® VOBs.
A resource group category can contain resource groups and other
resource group categories.
When you create a new data configuration file, a root resource
group category names Resources is created by default.
