What are the choices for data cube materialization? Explain the strategies for cube computation. [5]
Data cube computation is an essential task in data warehouse implementation. The precomputation (materialization) of all or part of a data cube can greatly reduce response time and enhance OLAP performance. However, it is challenging because it may require huge computational time and storage spac...
