Let's make a point clear: MySql is a database server and not a language. SQL is the accepted standard language for manipulating relational databases, including, but not limited to MySql. MySql implements a subset of SQL and extends the language with special functions.
There are several tutorials and book available online that deal with SQL and data modelling in general. SQLyog may help you if you decide to use MySql to learn SQL as it provides an GUI for editing SQL statements (and a lot more, but you won't need most of its features in the near future).
