Modifier and Type	Class and Description
class	AdditiveExpression
class	AggregateExpression Expressions containing aggregates are computed in two phases: phase 1: the input tuples are passed to a list of expressions composed by the group by columns and the list of aggregates phase 2: the output tuples of phase 1 are passed to the list of original select list.
