Simulation experiments which we carried out confirm the high performance of the Multidimensional Linear Dynamic Hashing (MLDH) method. For example, for uncontrolled splits, with b equals 5 and b prime equals 1, an average of 1. 09 accesses is necessary, irrespective of d (the dimension of the space), while maintaining an average load factor of 0. 67. On the other hand, for controlled splits, even with a threshold load factor of 0. 9 for b equals 10, b prime equals 2, we obtained an average number of accesses of 1. 74. Storage mappings for these splitting strategies were also developed, and as a byproduct we obtained a quite general class of extendible array storage mappings. We further intend to experiment with different distributions of attribute values in real files to see which splitting strategies are suitable.
