Zusammenfassung

Dieses Papier erweitert unsere frühere Arbeit über algebraische Spezifikationstechniken für Datenbanksysteme. Die Semantik algebraischer Spezifikationsschemata ist nun als eine Komposition von drei elementaren Konstruktionen gegeben:

  1. 1.

    TABLE-construction (die Konstruktion der Objekte einer höheren Ebene aus Objekten unterer Ebenen durch Tabellierung)

  2. 2.

    ENRICHMENT-construction (die Konstruktion von Operationen einer höheren Ebene aus Operationen unterer Ebenen)

  3. 3.

    RESTRICTION-construction (Einschränkung der Objekte einer höheren Ebene auf konsistente Daten)

Diese Definition der Semantik erlaubt die Angabe einfacher Kriterien für den Nachweis der Korrektheit.
