This is actually often something people don't pay much detail to. It is "Unlimited Databases".
What does that really mean?
Well, first you have to understand that there's a difference between the words 'database' and 'database size'. Unlimited databases means that you can have as many databases as you want, but of what use is an unlimited database if the disk size for the database is just 50MB for example?
Do not be deceived by the number of databases a web host company is willing to offer.
Do a little research, and don't be afraid to ask questions.
