Explain the optimization techniques in data cube computation. [5]
Data cube computation is an essential task in data warehouse implementation. Precomputing 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 space. Optimization techniques ...
