On Performance Modelling of Data Base Management Systems - An Inductive Approach.
Abstract
This paper describes a simulation model in which user jobs are synthesized from basic building blocks. The modelling process consists of three stages: translation from a user view of data and processes dependent on the data base management system (DMS) into a standard form consisting of explicit access paths over logical data structures; translation of the logical structures and operations into block-oriented structures and operations on a virtual machine; and execution of a number of concurrent jobs on a real machine. This paper deals only with the last two stages. Standard forms for the logical structures and operations and for the virtual machine are described; they are as free as possible from the data view of the particular DMS. We describe a generalized modelling framework, which becomes a model of a particular DMS WHEN VARIOUS 'plug-in' MODULES ARE ADDED. The data representation features of a DMS enter as parameters for the second stage, while the resource management tactics are the parameters for the last stage. The proposed model structure is intended as a basis for DMS design experiments. (Author)
