Data warehouses differ significantly from traditional transaction-oriented operational database applications. Indexing techniques and index structures applied in the transaction-oriented context are not feasible for data warehouses.

This work develops specific heuristic indexing techniques which process range queries on aggregated data more efficiently than those traditionally used in transaction-oriented systems. The book presents chapters on:
– the state of the art in data warehouse research
– data storage and index structures
– finding optimal tree-based index structures
– aggregated data in tree-based index structures
– performance models for tree-based index structures
– and techniques for comparing index structures.
