Re: [ontolog-forum] knowledge base and DBs

Add views and recursion, SQL databases start looking more like a KB.

In my mind, one of the big differences between a database (db) and a
knowledge base (kb):

a databases store information, and may actually include calculated
information that is dependent on the stored information.  Basically, a
storage facility for known facts.

a knowledge base includes all that is in a database but also includes
the activity of inference from information, and has a far more
sophisticated model of hierarchical categories of information. A
knowledge base also includes all the standard First Order Predicate
Calculus operations: AND OR NOT FORALL THEREEXISTS as well. Knowledge
bases handle infinite groups of facts as it were.

Does anyone have something to add to this?
