Transaction Rollback In Networked Mode

[Kang Wang]

Hi guys,

Do we have to worry about rolling back failed transactions? For example, if a user books a room, the transaction is completed on the server and the response cannot be sent back to the user. Therefore, the user gets an error message (something like "connecton lost") and he/she can't tell if the room has been booked until another search. In this case, are we supposed to keep the transaction result or roll it back?

Thanks
Kang

I wouldn't bother with rollbacks...especially in a situation like this.

Also, unless your instructions state otherwise you don't have to implement rollbacks. You can always describe why or why not in your choices.txt file.

Hi Yevgeniy,

Thanks very much. My instructions don't explicitly ask for any rollback scheme. I guess I should just document my choice.
