yes i can add manually price > 500000 but you imagine the horror to manage such code that will finnally for 100% result in bug one days. for exemple price of house in center russia a not the same as price of house in new york, etc... no impossible to manage (because we will need to do the same for the rent, the room, the date, etc..). my solution work in most of the case without any "manual customization" ... just the speed of the commit and the bug of corruption of the database that destroy everything
