Examines the existing distributed data base file allocation models and gives a breakdown of the models by type deterministic one-phase, deterministic multi-phase, stochastic discrete, stochastic continuous. The relationships and identities used to describe the models are divided into four categories file information and parameters, transmission characteristics, computer characteristics, and costs. In the investigations which led to this paper it was seen that the models defined were initially very general. The models included relationships which were very detailed in their description of the file allocation problem. In previous analyses using these models, simplifications were often made for computational tractability. Many of the assumptions and models ended up so restricted in scope or detail as to be unrealistic. There is a great need for more work in this area. Author
