摘要: Fur die Organisation von geometrischen Daten, wie sie z.B in CAD-Anwendungen vorkommen, durch Datenbanksysteme (DBMS), benotigten diese Raum-Zugriffsstrukturen, ein effizientes Suchen bezuglich der Attribute Daten gewahrleisten. In diesem Bericht geben wir eine Ubersicht bekannten Raum-Zugriffsstrukturen. Daruberhinaus wird Aufteilung Raum-Zugriffsstrukturen drei Klassen vorgenommen, wobei jede Klasse Technik charakteriziert ist, es erlaubt Raum Zugriffsstrukturen aus einer beliebigen mehrdimensionalen (Punkt-) Zugriffsstruktur zu generieren.
