What is the use of cantraints?
Constraints are used to enforce rules and limitations on the data that can be stored in a database table.

What is data consistency constraints?
Data consistency constraints are rules that define the allowable values and relationships within a database to ensure that the data remains accurate and reliable. These constraints help maintain the quality and integrity of the data by preventing conflicting or incorrect information from being stored. Examples include primary key constraints, foreign key constraints, and unique constraints.
What is integrity problem in dbms?
Integrity problems in a database management system (DBMS) refer to issues such as data inconsistencies, duplicates, or inaccurate information that may arise due to violations of data integrity constraints. These constraints ensure the accuracy and validity of data stored in the database by enforcing rules such as unique values, referential integrity, and domain constraints. Failure to maintain data integrity can lead to errors, data corruption, and compromised reliability of the information stored in the database.
