Let the Sunshine In: Software support engineer in Tokyo

I recently purchased Globalsat GH-625. It had a CD-ROM in the box and I was surprised to find that MySQL is included in it. Yes, you guessed it right. The software uses MySQL to store my running/bicycling/walking logs, including latitude/longtitude/altitude, heart rate, lap time.

MySQL is used from the application as 'Embedded', as opposed to 'Deeply Embedded' (Yeah, I learned these are the correct parlance in MySQL world at recent user conference). So..., I can access it from 'mysql' client tool like below. I hope I can
do schema analysis to find entity relationships soon. I think MySQL has a cool tool to do it.

bash-3.2$ /c/e/Program\ FilesW2K3/GSsport/MySQL/bin/mysql -u root -ppassword --port=3308
