MySQL® is a remarkably good relational database server available FREE of charge (in most instances, read the license) from its developers, MySQL AB, at http://www.mysql.com. MySQL runs on Linux, Mac OS X, most flavors of UNIX, and Windows.
MySQL AB also has MySQL clients freely available at the same location.

SQL (Structured Query Language) is a relational database query language invented by IBM and used almost universally for issuing queries to relational databases, including most non-IBM databases, and including MySQL. (In fact, that's why it's called "MySQL").

The Place of SQL
Of course, most users don't interact with database systems like MySQL directly through SQL. Instead, they use pre-designed forms which contain the needed SQL queries "under the hood". Designing these forms is something of a black art -- that's why you might hire consultants like us.
