Abstract
A sequence of queries is divided into stages, where each stage involves one pass over the data, such that the sequence of queries can be executed using the minimum number of passes over the data. The sequence of queries may be processed into a functional dependency graph that represents the relationships between query parameters (signals) and query operations, and the functional dependency graph then may be processed to divide the queries into a number of successive stages such that each stage includes queries that can be executed based on data that exists prior to execution of that stage. A sequence of queries may, and often does, require that one or more intermediate values or datasets be generated using an aggregate function.
