Database Fundamentals — Question 100
A view can be used to:
Answer options
- A. Save an extra copy of data stored in a separate table.
- B. Limit access to specific rows or columns of data in a table.
- C. Ensure referential integrity.
- D. Save historical data before deleting it from the base table.
Correct answer: B
Explanation
The correct answer is B because views can be designed to expose only certain rows or columns of a table, providing a layer of security. Options A, C, and D are incorrect as views do not physically store data, do not ensure referential integrity, and do not function as a means to save historical data.
