In Teil I erhalten Sie einen allgemeinen Überblick. Bevor Sie etwas über SQL selbst erfahren, erkläre ich Ihnen, was Datenbanken sind und wie sie sich von Daten unterscheiden, die die Menschen des 20. Jahrhunderts in groben, unstrukturierten Steinzeitdateien speicherten. Ich werde die gebräuchlichen Datenbankmodelle beschreiben und die Systeme erläutern, auf denen diese Datenbanken arbeiten.
