Small Materialized Aggregates (SMAs for short) are considered a highly flexible and versatile alternative for materialized data cubes. The basic idea is to compute many aggregate values for small to medium-sized buckets of tuples. These aggregates are then used to speed up query processing. We present the general idea and present an application of SMAs to the TPC-D benchmark. We show that exploiting SMAs for TPC-D Query 1 results in a speed up of two orders of magnitude. Then, we investigate the problem of query processing in the presence of SMAs. Last, we briefly discuss some further tuning possibilities for SMAs.
