Add to basketThis item is printed on demand - it takes 3-4 days longer - Neuware -Dieses Buch stellt, in Form eines Lehrtextes, den Datenbankansatz vor, der durch CODASYL (Con!erence on Data Systems Languages) zwischen 1967 und 1971 entwickelt und in zahlreichen Berichten von CODASYL zwischen 1968 und 1975 veroffentlicht wurde. Es sind heute mehrere Im plementierungen dieses Ansatzes auf dem Markt verfugbar, darunter DMS 1100 (Univac), IDS/2 (Honeywell), IDMS (fUr IBM und ICL Systeme) und UDS (Siemens). Der vorliegende 'Text ist kein Ersatz fUr die Benutzer handbucher dieser Systeme, sondern vielmehr als eine hoffentlich wert volle erganzende Erlauterung fur Benutzer von Systemen, die auf dem CODASYL Ansatz basieren, gedacht. Daruberhinaus bietet dieses Buch eine gute Grundlage fUr die Ausbildung von Studenten an Universitaten oder Fachhochschulen. Ich bin davon uber zeugt, dass in den 80iger Jahren die meisten Informationssysteme unter Zuhilfenahme von Datenbanktechniken aufgebaut werden. Die wahrend der ersten zehn Jahre entwickelten konventionellen Techniken, die hauptsach lich durch die weitverbreitete Benutzung von Magnetbandern als Speicher medium gekennzeichnet waren, werden dagegen mehr und mehr in den Hin tergrund treten. Vielen Lesern werden die haufigen Diskussionen zwischen Vertretern der Praxis und der Forschung uber die relativen Vorteile der verschiedenen Datenbankansatze bekannt sein. Es ist sicherlich gut so, dass ein An wender unter den verschiedenen Angeboten auf dem Markt wahlen kann. 420 pp. Deutsch.
