Abstract

Die Art und Weise, auf die man CODASYL DBMS in Komponenten aufteilt ist von Implementierung zu Implementierung unterschiedlich. In einigen Fallen ist dies lediglich ein terminologischer Unterschied, in anderen Fallen ist er fundamentaler. Aus Referenzgrunden werden die 5 Hauptkomponenten wie folgt bezeichnet: 1. Schema Datenbeschreibungssprache (Schema Data Description Language) 2. Subschema Datenbeschreibungssprache (Subschema Data Description Language) 3. Datenmanipulationssprache (Data Manipulation Language) 4. Datenbank — Kontrollsystem (Data Base Control System) 5. Geratekontrollsprache (Device Media Control Language)
