Database schemas in web applications often mimic the site's structure, reflecting entities like users, posts, and comments. SQL becomes vital in designing and maintaining these structures.

It's not just about creating tables; it's about maintaining relationships between these tables. Normalization, a crucial branch of SQL, helps manage these relationships efficiently, reducing data redundancy.
