The transactions like adding an employee, enrolling a student in a course are examples of _______

  • A.Logical
  • B.Physical
  • C.None
  • D.Theoretical

Answer: A

Correct answer: Logical

Adding an employee or enrolling a student is one logical operation as the user sees it, though the DBMS may carry it out as several physical writes to different tables and index pages. Keeping the two levels apart is what lets a transaction be treated as indivisible.
