Re: Abfrage in einer Hierarchie
Spontan würde ich die Tabelle
Einkaufswagen_Ware_assoc (einkaufswagen_id, ware_id)
denormalisieren in
Einkaufswagen_Ware_assoc (kunde_id, einkaufswagen_id, ware_id)
Da Einkaufswagen_Ware_assoc eine reine "Schlüssel-Tabelle" ist, sollten die Daten auch nicht zu sehr explodieren.
Mal so als Idee..
Grüße
Thomas
