Hierarchical Datacubes

Many approaches have been proposed to pre-compute data cubes in order efficiently respond OLAP queries warehouses. However, few solutions integrating all of the possible outcomes, and it is this idea that leads integration hierarchical dimensions into these responses. To meet need, we propose, paper, a complete redefinition framework formal definition traditional database analysis through prism dimensions. After characterizing cube lattice, introduce its most concise reduced representation, closed cube. It offers compact replication so as optimize storage space by removing redundancies strongly correlated data. Such are typical warehouses, particular video games, our field study experimentation, where dimension attributes widely represented.
