The component of the database that prevents both students from getting the last seat is: transaction isolation
Data that enters the database are expected to maintain accuracy and also be consistent with the database structure.
So, when both students request for the last seat, the possibilities are:
- <em>Student A gets the seat</em>
- <em>Student B gets the seat</em>
The following is not a possibility
- <em>Both students get the seat</em>
- <em>None of the students gets the seat</em>
The above highlights means that, only one of the students would get the seat.
This is possible because of the concept called transaction isolation.
The transaction isolation ensures that the data requested by a user is <em>complete </em>and such data maintains <em>competency</em>.
So, when a student gets the last seat, the <em>next student </em>would not get the same seat (<em>or any other seat</em>), because a transaction has already been completed.
