Real world data can be quite complex. It is often best to represent data using several tables instead of just one, focusing instead on the relationships between tables. This second MySQL webinar will continue where the previous webinar left off. We will cover primary and foreign keys, data constraints, and a variety of joins. We will also introduce some basic design considerations such that have to do with data relationships. The webinar assumes the user has watched the first webinar. Some Linux command line interface knowledge is required.
