Abstract:	The problem of finding optimal distribution of a database over a computer network to facilitate parallel searching for a set of database queries is analysed in this paper. The parallel searching of multiple segments required by the queries lowers the response time considerably. Procedures for finding the optimal distributions in a network to maximally exploit the parallel search capability with or without redundancy of segment types are proposed.
