MySQL is an open-source relational database management system that uses SQL for data manipulation and is widely used in web applications and content management systems.

What is a primary key?

A primary key is a column or combination of columns that uniquely identifies each row in a table, ensuring data integrity and enabling efficient data retrieval.

SQL joins combine rows from two or more tables based on related columns. Common types include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN.
