Database Design, Database Metrics, Database Quality 1.0
Early in the development of database technologies, two measures of quality, storage and performance, stood out from the rest because of their effect on the cost over the life cycle of the information source. In recent years, the costs associated with these two items have drastically decreased and, with advances in computing technologies, will continue to be less dominating as a significant cost consideration. This paper addresses three other aspects of the database modeling and design process that have an impact on the usability and life cycle cost of the database - assisting users in performing information analyses, enhancing the semantic clarity of each object in the database, and addressing the overall issues of complexity and increasing the ease of modification. The important issues in each of those three concepts are elucidated and possible measures or metrics to assess the overall design with respect to those factors are presented.
