Uhm.... Locking a whole table because of a single flight?No, its most likely a page lock will lock an entire flight or class of seat assignments. BTW, thats Chaos. ;-)

Gee I mention hotel reservation systems. Yet you seem to let it slide in to the vapor. Airline reservations, etc ...
The point is that there *ARE* applications which bennifit by having row level locking.

As Pablo pointed out, yes, there is overhead involved. Yet, that is always the case. Costs vs. Bennifits. Row level locking has some bennifits which out weigh the costs. Now, as I said earlier, arguing that product B is better because it lacks an option that product A has, is silly. Its like saying that your car is a better car because it has disc breaks, over a car which has anti lock disc breaks. OK? Now do you see my point.

Why don't you tell us what features Sybase has that Informix doesn't? OK? Received on Mon Dec 01 1997 - 00:00:00 CET
