Data integrity constraints are used to:
Correct answer: D. Improve the quality of data entered for a specific property (i.e., table column)
- A. Control who is allowed access to the data
- B. Ensure that duplicate records are not entered into the table
- C. Prevent users from changing the values stored in the table
- D. Improve the quality of data entered for a specific property (i.e., table column)
Explanation
The correct answer is (d) Improve the quality of data entered for a specific property (i.e., table column). Data integrity constraints are rules that enforce specific conditions on the data in a database table. These constraints help to ensure that the data is accurate, consistent, and reliable. In conclusion, data integrity constraints are primarily used to improve the quality of data entered into a database table.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
