Abstract
Methods are disclosed of processing a set-level query across one or more attributes, the query being grouped by one or more attributes, whereby groups that satisfy the set-level query may be aggregated over one or more attributes. The methods use bitwise arithmetic to efficiently traverse bitmap and bit-slice vectors and indexes of a data relation to determine groups that solve the set-level query.
