1- Assume that two students are trying to register for a course in which there is only one open seat. What component of a database system prevents both students from being given that last seat?
Homework Answers
Due to the isolation property (ACID) both students can not register for the last seat.
Transaction isolation will prevent both the students to register for one last seat. The student that has initiated the transaction before the other one will be given the seat. The database will be locked for the second student during the period of transaction of the first student.
Hope this helps.

6. Two sections of a class contain 50 students each who just did a midterm exam. In the first section 90% of the students passed the exam, in the second section only 70% of the students passed. Two friends randomly chose a sections at enrolment, but chose 1 the same one. Here we assume that we pick two students independently at random with replacement (so there is some chance that two students can end up being the same one). a....
