Some hosting provider offering you unlimited domain hosting but only give you very limited mysql database number, this restricted the amount of websites that you can host. Its common today that each website will utilise one mysql database. Example is this lunarpages review blog made from wordpress blog, and it uses one mysql database as well.

You can create new mysql database when you login to lunarpages control panel and go to mysql database section. Add new database and remove existing mysql database is an ease via lunarpages cpanel.
