Multi-Dimensional Expressions (MDX) provide an interface for asking several related OLAP queries simultaneously. An interesting problem is how to optimize the execution of an MDX q...
Computing multidimensional aggregates in high dimensions is a performance bottleneck for many OLAP applications. Obtaining the exact answer to an aggregation query can be prohibit...
One of the critical deficiencies of SQL is lack of support for ndimensional array-based computations which are frequent in OLAP environments. Relational OLAP (ROLAP) applications ...
