A table is often divided into a number of groups. Groups provide a way of showing common headings for a group of related rows. Groups often have subtotals. For example, a sales report may show totals per sales rep and region.
A group is defined by a group key. The key is a column from the query. If the group key is a time field then user often want to group on an interval such as month or quarter.
