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.

Hi!
Okay, so -
To make a C++ class, we have to use the keyword <em>class </em>followed by the class name, and a pair of curly braces which will be our <em>class body</em><em>. </em>
Our class body is what holds all of our constructors, functions, and data members.
So, to write a completely empty class - we would just have to simply write:
<em>class Acc1
</em>{
};
<em />Note -
All classes must end with a semi colon! This is just a standard rule we follow since it was how C++ has been defined. If you were to leave the semi colon out, you would get a compiler error! =)
Highlight the row(20), then click on the insert cells button under the home ribbon.
Im guessing a cell is named by the scientist that found that cell in the fist place.
