How can data consistency and integrity be ensured in MySQL?

In MySQL, you can ensure data consistency and integrity by following these methods:

1. Using primary and foreign key constraints: Defining primary and foreign keys can ensure the relationship between data tables and prevent inconsistencies between data.
2. By using triggers, specific operations can be executed before or after data insertion, update, or deletion to ensure data integrity.
3. Transaction Usage: Transactions can group a series of operations together so that if any one operation fails, the entire transaction is rolled back to prevent data loss or inconsistency.
4. Constraints can be defined at the column-level or table-level, such as NOT NULL, UNIQUE, DEFAULT, etc., to ensure data integrity.
5. Utilizing stored procedures and functions ensures data consistency and integrity when executing complex data operations.

By utilizing the above methods, it is possible to effectively ensure data consistency and integrity, guaranteeing that the data in the database is accurate, complete, and reliable.
