The problem of multidimensional file partitioning (MDFP) arises in large databases that are subject to frequent range queries on one or more attributes. In an MDFP scheme, the search attribute space is partitioned into cells, which are mapped to physical disk locations. This mapping preserves the order of the search attribute values so that range queries can be answered most efficiently, while maintaining good performance for other types of queries. Recently, MDFP schemes have been suggested to include both dynamic and static file organizations. Optimal and heuristic MDFP algorithms are developed for the static case. The results of extensive computational experiments show that the proposed heuristics perform better than known static ones. It is also shown that incorporating a static algorithm into a dynamic MDFP such as a grid file at conversion and/or periodical reorganization points significantly improves the resulting storage utilization of the data file and decreases the size of the directory file.
