Abstract
Mit der Verwendung des Attributkonzepts von freeWAIS-sf ist eine Befragung mehrerer WAIS-Datenbanken nur dann möglich wenn die einzelnen Datenbanken jeweils die gleiche Anfrageattribute anbieten. Basierend auf dem Konzept der Datenunabhängigkeit wird eine externe Sicht auf mehrere freeWAIS-sf Datenbanken präsentiert, die es zuläßt, auch Datenbanken mit unterschiedlichen Anfrageattributen parallel zu befragen; die Heterogenität der zu befragenden Datenbanken wird vor dem Benutzer verborgen. SFgate ist eine Gateway zwischen dem WWW und freeWAIS-sf, welches den hier vorgestellten Ansatz implementiert
