Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - A prototype database is a model of a database whichexhibits the desired properties, in terms of itsschema and data values, of an operational database.Database prototyping has been proposed as a techniqueto support the database application developmentprocess. Existing work on this area has been widelyignored in practice mainly on the grounds that itsbenefits, i.e. an increase in the quality of theresulting software systems, do not justify the costsof developing and using a satisfactory prototype ofthe database under construction.Increasingly more software development projectsconsist of extending or enhancing existing systems,as opposed to developing new ones. Examples includelegacy information systems migration and WEB-enablingexisting systems. In these types of projects, usingthe entire operational database may not becost-effective and a carefully selected subset may bemore appropriate. The availability of operationaldata and a database schema can significantly reducethe effort required to build an appropriate prototypedatabase to support the project at hand. This workinvestigates how such a prototype database should beconstructed.…
