| Shrnutí: | It is possible to produce different database designs based on the same set of
requirements to a database. In this paper, we present a decision support
method for comparing different database designs and for selecting one of them
as the best design. Each data model is an abstract language that can be used
to create many different databases. The proposed method is flexible in the
sense that it can be used in case of different data models, criteria, and
designs. The method is based on the Analytic Hierarchy Process and uses
pairwise comparisons. We also present a case study about comparing four
designs of SQL databases in case of PostgreSQL? database management system.
The results depend on the context where the designs will be used. Hence, we
evaluate the designs in case of two different contexts - management of
measurements data and an online transaction processing system.
