A Multi-Resolution Block Storage Model for Database Design
We propose a new storage model called MBSM (Multiresolution Block Storage Model) for laying out tables on disks. MBSM is intended to speed up operations such as scans that are typ...

Reducing Order Enforcement Cost in Complex Query Plans
Algorithms that exploit sort orders are widely used to implement joins, grouping, duplicate elimination and other set operations. Query optimizers traditionally deal with sort ord...

Integrating Semi-Join-Reducers into State of the Art Query Processors
Semi-join reducers were introduced in the late seventies as a means to reduce the communication costs of distributed database systems. Subsequent work in the eighties showed, howe...

Exploiting self-monitoring sample views for cardinality estimation
Good cardinality estimates are critical for generating good execution plans during query optimization. Complex predicates, correlations between columns, and user-defined functions...

Implementing Data Cubes Efficiently
Decision support applications involve complex queries on very large databases. Since response times should be small, query optimization is critical. Users typically view the data ...
