On most websites, content is stored in a database and served to visitors upon request. Databases are very fast, but there's lots of things that you can do to enhance its speed and make sure you won't waste any server resources.

This first tip may seems obvious, but the fact is that most database problems come from badly-designed table structure.

When creating a database, always put information on various tables, use clear naming standards and make use of primary keys.
