title: Where can I get a large sample database for practising MySQL query optimization
body: <p>Can anyone give a reference to a substantially large sample database which I can import into MySQL to test and learn optimization and benchmarking? <br>The database should have at least 6-8 tables with lots of foreign keys in between them, i.e a complete database. The <code>MySQL</code> <code>employees</code> database looked promising, but the download page has 3 download links, clicking on any of which opens a page in a browser with a god-awful amount of binary data, dont know what to do with that.</p>
