Oh, but it is very amusing to see the arrogance and closed mindedness on your side.
To drive the point home to you, let's say we were debating languages. And you guys came with Pascal, you know there's this language Pascal, it has this blazingly fastc ompiler, generates compact code, and is way cool. It does the job in real projects, and all that jazz.
So we don't need the theory of programming languages, and programming language semantics, cause we have our model which is Pascal itself. And that's it, Pascal is so much superior to other language implementations and to any theory.
To which we say : Huh ? There's nothing new under the sun. There's absolutely nothing that Pascal does essentially better than, say, ML, C, Visual Basic or Java. And Pascal has a tiny niche, which is in itself a problem.
So the little tiny thing about Pick/MV is that it puts record together in a cluster. Big deal ! And allegedly it has a good quality implementation, but this is not easily verifiable in comparison with other DBMSes. And it may have an integrated development with screens and a tiny procedural languages and stuff like that, who cares ?
And it doesn't have tons of other things including basic integrioty constraints.
So, who cares ?
And it is you who quarrels against "relational model" . At best you can quarrel with Oracle 9i or PostgreSQL, but claiming that the Pick/MV "data model" is so much better than relational model is entirely non-sensical. Received on Thu Oct 23 2003 - 02:29:45 CEST
