In MySQL, constraints and joins are fundamental concepts used to ensure data integrity in a database and query data from multiple tables. Constraints are rules enforced on the data columns of a table. Constraints provide the accuracy and reliability of the data within a database. Joins in MySQL combine rows from two or more tables based on a related column.
