Dynamic Model for Distributed Data-Bases.
K. Dan Levin, Morgan,Howard Lee · Defense Technical Information Center (DTIC) · 1975
A multi-period model of programs and data file assignment in computer networks is presented. In reality, access request patterns are subject to change over time, thus, an optimal file assignment at one period is no longer optimal in the next period. An optimizing procedure for the assignment of programs and data files over time is suggested. This procedure, takes into account both the dependencies between programs and data file and the transition costs incurred by file movements from one assignment at a given period to another assignment at the next period.
