Sorry, it's a logical fallacy. Have you ever heard it said that "the whole is greater than the sum of its parts"?
You need to contact Oracle, Microsoft, and IBM and inform them that Relational Database technology is based on a logical fallacy. Contact all their customers too, and destroy your credit cards.
You can confirm the fallacy of composition that I listed in any good book on logic or logical fallacies. Oh, it's real.
