Naaaaaaaah. The term post-relational database was coined by some nefarious characters in marketing at VMark (I can't name them but at least one of the people involved had a first name that started with "Dav" and a last name that ended in "ryant"), and it means absolutely nothing. The term was propagated a little later by an article written by a Microsoft guy.
However "Multi-Value", a term which I hate with a vengeance, sounds like a moniker for soap powder or a collection of self-help books in the remainder bin at the local foo-foo new age store. It was made up at a Spectrum show, a meeting to which technicians like myself were not invited because the marketing people would know better; come the revolution brothers, up against the wall, pop pop pop.
jBASE is more of an application framework based on key/value pairs, a primitive but surprisingly useful data model that everyone abuses and can be kind of faked into being relational if you do all the hard work in your application. It isn't an implementation of the relational model itself any more than any other system derived from the original systems whence it came is.
However, don't confuse the partial implementations of the relational model currently marketed as RDBMS with the relational model either. Knowing one or two Oracle developers... well let's just say that I do :-)
