Hi all,

I'm again with 48-hour rule...
Is it bussines rule or database rule?

Theoretically it's a bussines rule, but than this means I have to transfer all reserved records from DB layer to Bussines layer and apply 48-rule filter there... What I would not like...

certainly it is a business rule. in fact my Data class contains no reference to rooms what so ever. So it can easily be used to write customers or hotels to a similar database file. You could also decide not to implement this business rule.
