Something that is attractive, for beginners or perhaps when prototyping is that you don't have to declare a table. You can just insert tuples into a predicate whose name you provide and they go in and you've defined a relation just by using it. Much of my point in raising this discussion is that there are features that the NoSQL folks are implementing that are useful in some cases. Things they are doing like eventually consistent distributed stores are really required at sufficient scale, but there are other great ideas. SQL's storage model is not the only way, nor should it be. We shouldn't have to abandon the relational model to get such features, but we *do* have to abandon SQL to get them. And good riddance. I would like to have relational stores providing such features before some monstrosity like Mongo or CouchDB becomes so entrenched we'll never be rid of it.
