    Can you clarify your question? Are you talking in OLAP terms? Or do you mean, how do you define levels of aggregation for a report written against a relational DB using straight SQL? If you mean the latter, the Report Designer has a very intuitive/simple interface for defining those levels of aggregation. It's very similar to most report writing tools. There is a navigation tree for the report design that breaks down all aspects of the layout (i.e. Report header, page header, etc). There is a point in this tree that will allow you to add group values from fields available in your query resultset.

    Here's a screenshot:
