• Basic knowledge of MySQL and SQL operations.
• Access to a MySQL server for testing and experimentation.

Indexes are data structures that improve the speed of data retrieval operations on a database table. They are similar to the index in a book, which allows you to quickly find specific topics without scanning every page. In MySQL, indexes can be applied to columns to speed up queries involving those columns.

Ensure that the columns used in joins have indexes. This can significantly reduce the time taken to execute join operations.

Efficient SELECT statements can greatly improve query performance.
