Well, it is a 'model', not the real thing. Anyway, I have to disagree with you. Relational techniques for modelling are not 'purely' subjective, they have a very sound theoretical basis. Obviously, there are subjective aspects, but the sound fundamentals can carry you pretty far. OO modelling techniques, OTOH, are very close to 'purely subjective'.
