Statements of fact have no associated order; there is no concept of first fact or last fact or nth fact. They are just (presumably) true statements. The system is allowed to do anything it likes in the interests of speed, as long as it always gives you all the facts you asked for. SQL databases follow the Information Principle, which requires that all the infromation content of the database is represented explicitly as values of attributes of rows *and in NO OTHER WAY*. If one fact must be distinguised from another in terms of the time (or sequence) at which it became known, then the time (or sequence) must be part of the fact. Once you have the sequence information you can use it to order the facts when you finally report them. Again in the hope this is a homework question, ask yourself, why was the Information Principle invented? Why is it a good thing, and not the pain the backside it might seem at first? HTH. Art
