I'll take that bait -- if one were to model data as if for an XML document, for example, then you would not have to put the data in 1NF and could retain "multivalues" in your model. First normal form is perhaps the most obvious way thast the relational model loses such information (as ordering) when modeling propositions by splitting them into so many propositions. This is the same way we modeled data in the 70's (we as a profession) when storing it in indexed sequential files with tables permitted as fields in records. It is the same way data is modeled in PICK and pretty much every data model, I suspect, other than relational. So, start by tossing out 1NF and that will make a big difference in this area in my opinion. Cheers! --dawn
