Abstract

Retrieval queries to a relational data base system or any data base system supporting set-like views of data often require the exploration of the product of arbitrarily many relations or sets. When the exploration is by nested iteration over the underlying sets, different orders of iteration require different volumes of data transfer, hence different response times. This paper describes selection procedures for the optimal order of iteration and for the expected optimal order when the subsetting predicate can be applied to proper projections of the product.
