# Working with dataset attribute groups

A dataset attribute group is a user-defined logical grouping of dataset. Datasets within a dataset attribute group are typically related according to specific criteria. You can define a dataset attribute group based on many things including dataset name or mask, volser, SMS class, or one or more dataset attributes (for example, Percent Free, Last Backup Date Time, etc.). After you define a dataset attribute group, you can use the Dataset Attributes Group Summary workspace to view aggregated metrics for the group as a whole. From this workspace, you can drill down to the Dataset Attributes Group Details to display metrics for each dataset in the group.

Use these procedures to add, edit, and delete dataset attribute groups.
