mySQL Database Username doesn't have a "_" before it.. is that okay?

Hi Gina,

The underscore dictates namespaces which is a very relaxed convention as it's optional whenever using MySQL servers, essentially for Zac his hosting username would be used as the namespace allowing his databases to be grouped together instead of separated out.

For example if my username was chris and I used a cPanel type control panel I would see databases created in the following fashion.

chris_
  database_one
  database_two
  database_three

Now remember as I said this is a very relaxed convention and you don't have to use it but if you say had a website with different software running under the same domain you would generally use the name of the domain followed by the database, for example if your domain is example.com you would do something like.

example_
  database_one
  database_two
  database_three

another_domain_
  database_one
  database_two
  database_three

But what good does this do?

If you ever find yourself with a list of cluttered database names namespacing them fixes the overall issue of clutter and allowing better visibility, I always use this convention whether or not it's just going to be a single database as it's just easier to manage in the long run.

Hope that helps.
