Abstract

There is a need for a knowledge based assessment approach to assessing database quality using a quantitative scoring system. Traces international studies in this field and describes Finnish studies carried out by the Finnish Society for Information Services into the quality of Finnish databases. The latter projects are evolving into a system of continuous monitoring. Describes a prototype for a metrics evaluation system QAD (Quality Assessment of Databases) being developed to carry this out
