Abstract
Systems, methods and articles of manufacture are disclosed for generating a relational database query from an online analytical processing (OLAP) query against a cube. The cube may have dimensions, each dimension having a hierarchy of members. A level of the hierarchy of a dimension of the cube may be identified from which the OLAP query accesses a number of members exceeding a predefined threshold count of members. A relational database query may be generated that includes a predicate for at least one member from at least one level above the identified level in the hierarchy, instead of a plurality of predicates for members from the identified level. The relational database query may be generated from the OLAP query, from a definition for the hierarchy, and from the accessed members from the identified level. As a result, the relational database query may include fewer predicates and may be executed more efficiently.
