Key Points
- An Integrity constraint is a rule that ensures the accuracy and consistency of data within a relational database.
- In this context, the constraint ensures that an employee's salary should not exceed Rs. 12,000.
- Integrity constraints can be applied to ensure that the data entered into a database adheres to certain rules or conditions.
Additional Information
- Referential constraint: This type of constraint ensures that a foreign key value always points to an existing row in another table, maintaining referential integrity between tables.
- Over-defined constraint: This term is not commonly used in database terminology. It might imply an excessive or redundant constraint, but it is not a standard term.
- Feasible constraint: This term suggests a constraint that is practical and possible to implement but does not specifically refer to database constraints.

Understanding Integrity Constraints
Integrity constraints are rules that ensure the accuracy and consistency of data within a database. They play a crucial role in maintaining the quality of information stored. In this context, the statement "Employee salary should not be greater than Rs. 12,000" represents an integrity constraint for the following reasons:
Types of Constraints Explained
- Integrity Constraint: This constraint ensures that data adheres to specific rules. In this case, the rule is that employee salaries must not exceed Rs. 12,000. This maintains data validity and prevents erroneous data entries.
- Referential Constraint: This type of constraint ensures that relationships between tables remain consistent. For example, ensuring that an employee ID in one table corresponds to an existing ID in another.
- Over-defined Constraint: This term typically refers to constraints that are unnecessarily complicated or redundant. It does not apply in this context, as the salary limit is a straightforward requirement.
- None of the Above: This option suggests that the statement does not fit any of the provided categories, which is incorrect since it clearly aligns with integrity constraints.
Conclusion
The statement about employee salaries being capped at Rs. 12,000 is indeed an integrity constraint. It ensures that the data entered into the system remains valid and within permissible limits, thereby protecting the integrity of the database.
