In the db.db file, every record have the field named size specifies the maximum number of people permitted in this room. And it's value is from 2 to 6.
My problem is when one client update the record to booking the room, but now the isn't full, then another client booking the room later, which client's name will be added to the owner field? Whether add all their names?

Hi Leo,
your have first to lock the record (so, that nobidy can change it.
Then you ckech if the room is still available.
If so, you book it and unlock the record.
That way the situation you just have described can never occur, since at the time a second client aquired a lock, the record will be booked by first client. Second client should get then just a message that a room is booked and should refresh search results.

Hi, Vlad.
Thanks for reply.
I think you don't understand my meaning, because my english isn't good. I'm a chinese.
I said that since every room can hold 2-6 men, then whether it can be booked 2-6 times. Because in my country, if take place this condition, the room will be hired by several people. So, the owner field should book whose name?
