Check out Aquafold’s aqua data studio, an sql visualization and editing tool that’s free for personal or educational use. Folks pay $$$ for tools like this in the commercial environment, it’s cool to see a company offer up a tool like this for free. If you’ve ever tried tinkering with mysql and struggled on the command line you will find this tool’s a godsend. Works across all platforms via java and also has binary downloads for Windows and OS X. If you’re running OS X these days there’s actually been a proliferation of these tools – YourSQL is my favorite but cocoamysql is also quite good. Any of the three is worth checking out if you’re interested in tinkering with mysql.
