This paper addresses the problem of determining the optimal location to place a fragment (object) in a distributed non-replicated database. The algorithm defined takes into consideration a changing environment with changing access patterns. This paper contributes by allocating data fragments to their optimal location, in a distributed network, based on the access patterns for that fragment. The mechanism for achieving this optimality relies on knowing the costs involved in moving data fragments from one site to the other. Embedded into the algorithm is a mechanism to prioritize fragments so that if there is a limited space on a specific node where many fragments are chosen to be allocated the ones with higher priority are placed before the lower priority fragments.
