Data in a MySQL/MariaDB database is stored in tables. A simple way of thinking about indexes is to imagine an extensive spreadsheet.

Times are changing, and possibly your hostname is too if you are reading this article. You may have come across a scenario within the business that requires you to change your hostname. You might ask yourself why you would need to change your hostname? The most common scenarios would be due to a domain name change, your business has changed its course, or because you have thought of something better.
Sometimes you might forget to renew the domain names before they expire. Unfortunately, this can be a time where a domain broker purchases the domain name out from under you.

As unfortunate as this may be, sometimes it is best to purchase a new domain name for cost efficiency.
