Abstract:
We present HIFUN, a high level query language for defining analytic queries, independently of how these queries are evaluated. We use four operations on functions, namely composition, pairing, function restriction and Cartesian product projection. These operations combine functions to create HIFUN queries in much the same way as the operations of the relational algebra combine relations to create algebraic queries. The contributions of this work are: (a) the definition of a formal framework in which to study analytic queries in the abstract; (b) the encoding of HIFUN queries either as Map Reduce jobs or as SQL group-by queries; and (c) the definition of a formal method for rewriting HIFUN queries and its mapping to rewriting Map Reduce jobs and SQL group-by queries.
