Abstract
Gibt eine umfassende Einführung in das Gebiet der relationalen Datenbanken. Es ist das erste deutschsprachige Werk, das sich auf die relationale Datenbanktechnologie beschränkt und zugleich die Datenbankentwurfsmethodik, Sprachaspekte, Systemarchitekturen und neuere Technologien umfassend und für den Praktiker verständlich behandelt. Bei der Datenmodellierung werden Abbildungsregeln zum Überführen eines Entitäten-Beziehungsmodells in ein relationales Datenbankschema behandelt, Normalformen diskutiert und ein unternehmensweites Datenmodell veranschaulicht. Die Diskussion relationaler Abfrage- und Manipulationssprachen geht grundlegend auf die Relationenalgebra ein, erläutert den Begriff relational vollständiger Sprachen und gibt einen Überblick über die bedeutenden Sprachen SQL, QUEL und QBE
