I'm starting a business website and will need to build two main databases. The first will store the user account information with the login name, password, user's address, payment/credit card info, email, etc. It is a transportation website and the second database will store information about freight such as the size of the freight, type, pick-up location, destination location, etc. This is my first time building a database and my site is hosted by yahoo. Do I need to create this database using MySQL on the yahoo site solutions?
