> When managing a database, speed and efficiency are crucial. As applications handle more data and become more complex, the performance of database queries plays a big role in keeping everything running smoothly. One of the best ways to make queries faster is by using indexes. Similar to a book’s index that helps you quickly find a topic, database indexes allow you to find specific data without searching through the entire database. This article explains the basics of indexing, how it improves query performance, and some simple tips for using indexes effectively. Whether your database is small or large, understanding how to use indexes can help keep your application fast and responsive.
