Abstract
A method and apparatus for performing a distinct count metric by utilizing aggregate navigation. For a distinct count query of an identifier of a detail table, where the query specifies zero or more restrictions, an aggregate table associated with the detail table is identified. It is then determined whether the aggregate table contains the identifier that is being distinct counted, and if so, whether the identifier is different in every row of the aggregate table. If it is, then the rows of the aggregate table that satisfy the specified restrictions are plain counted to obtain a result for the distinct count query. If the identifier is not different in every row of the aggregate table, a distinct count operation is performed on the rows of the aggregate table that satisfy the specified restrictions to obtain a result for the distinct count query.
