Abstract
Storing and/or accessing data in a transactional database, with use of the following technique: (i) selecting a set of base tables in a transactional database; and (ii) creating a factless materialized query table, having maximum sparsity, for the set of base tables. The set of base tables includes at least two base tables. The set of base tables includes a set of keys including at least two distinct primary keys. The factless materialized query table includes one record associated with each record in the set of base tables. Each record in the materialized query table includes a value for every primary key in the set of base tables.
