If you have a website but no database hooked up, I can create the database for you and send you the exported file (and guidance on how to hook it up to your website yourself). The database will be complete with tables, primary keys, and all other fields needed to store the data your website provides or asks. In addition to database design, PHP and MySQL can be added to your website to fill any of your web pages with data from the database (or to add data your users submit to fill out fields in the database).
