Example text

Zurück zur Bibliotheksverwaltung; da ja weder ein Lesername noch ein Buchtitel unsere strenge Schlüsselnorm bestehen können, bieten sich hier folgende numerische Schlüssel an: Buchnummer (buch_nr) und Lesernummer (leser_nr). Diese Attribute sind eindeutig und zeitkonstant. h. B. nie ein Buch ohne Nummer geben. Die von uns angegebenen Schlüssel sind keine natürlichen Objekteigenschaften wie ein Name, Titel usw. 2 Der Entity-Relationship Entwurf 21 ten Schlüssel haben den Vorteil der gewünschten Eigenschaften und ersparen uns eine große Attributkombination, wie Vorname, Nachname, Wohnort, Alter eines Kunden als eindeutige Merkmalskette.

Also teilt man die Tabelle auf. leser_fi! Normalform 32 2 Entwurf relationaler Datenbanken Nachdem die mehrwertigen Abhängigkeiten ausgemerzt wurden, liegen die Tabellen in der vierten Normalform vor. Da wir für die SQL-Befehle der folgenden Kapitel das Bibliotheksbeispiel benutzen wollen, veranschaulichen wir uns die sich aus dem Entwurf ergebenden betrieblichen Abläufe: Jeder Leser und jedes Buch erhält einen eindeutigen Schlüssel und wird mit allen zugehörigen Attributen in der jeweiligen Tabelle eingetragen.

Die Formulierung dieser Bedingungen erfordert aber den Einsatz des select-Befehls, deshalb müssen Beispiele dazu auf spätere Kapitel verschoben werden. Auch der Einsatz einer Assertion erfordert den Gebrauch von Abfragen, daher soll an dieser Stelle nur das Prinzip kurz vorgestellt werden. B. nicht mehr als 40% der ~_ _ _. 4. Aber wie gesagt, die Ermittlung der jeweiligen Anzahlen ist hier nur angedeutet. Wie diese SELECTs tatsächlich aussehen müßten, steht im nächsten Kapitel. Auf jeden Fall wird an diesem Beispiel deutlich, daß in die Bedingung mehrere Tabellen eingehen (vormerk, buecher) und daher ein Constraint nicht benutzt werden kann.
