HierCube library VCL V4.49

HierCube Library is a set of components for using by software developers, and designed to create fast, comfortable, and powerful OLAP-applications. HierCube allows to form OLAP-views "on-the-fly", not wasting time and memory for intermediate calculations. And for all that the performance of calculating almost doesn't depend on capacity of the cube and depth of hierarchical dimensions. The engine processes the fact table holding one million of records for less than a single second.
