Issues and methods for practical distributed data processing applications: II

This paper presents methods for the second of two key activities in the creation of practical distributed data processing (DDP) systems for business computing. The first activity, discussed in a companion paper, is to select a configuration of hardware and software to support the implementation of a multiapplication plan. The second, discussed in this paper, is to select data distribution and manipulation approaches for one application within the limits set by the results of the first activity. The paper assumes the definition of DDP established in the prior paper. It identifies some of the issues that constrain a commercial establishment with limited research funds and that justify the limitation of practical alternatives assumed as a basis for the methods.
