A methodology for the analysis of the workload in relational database systems.

ABSTRACT

The paper presents a pragmatic approach to the workload analysis in relational database systems. A set of extensional and statistical parameters is proposed, that can be easily estimated for the permanent relations of the database, and then computed for any derived relation. In this way arbitrarily complex transactions can be analized. Both the data access cost and the processing cost are considered. The latter is usually neglected, but may becom a relevant aspect in relational systems and provides an important information in the design and configuration of specialized systems, like database machines. The proposed methodology may also be valuable in database design, both at the physical and at the logical level. In fact it allows to compare on a quantitative basis different logical schemas for the same application, and suggests the appropriate actions to improve the physical data organization.
