mysql ist eine „relationale Datenbank”
<p><cite> Relationale Datenbanken versuchen die Realität in einem Datenmodell abzubilden.</cite>
<ul>
<li>Jede Zeile einer Tabelle ist ein Datensatz</li>
<li>Jede Zeile ( Tupel ) besteht aus Attributen ( die Spalten )</li>
<li>Über Primärschlüssel werden Beziehungen hergestellt</li>
<li>Eine Datenbank kann viele Tabellen beinhalten</li>
</ul>
