None what-so-ever. It is effectively the same as using
Microsoft Access apart from the fact that it is lacking in a GUI
like access. However, if you have it running on a PC, you can
download something like Heidi SQL which if memory serves me correct
is free. This then basically gives you your GUI. This means that
you can visually build the db and its tables rather than hand code
it.
The Mac has the ability to create php in dreamweaver and
serve the php pages with its built in apache server, so that might
be something to consider as you are already on a Mac. I use ASP
because I learnt this stuff years ago and have never really had the
time of bravery to go through the same pain as I went through many
years back!
Have you run MySQL on a Mac yet, and if so, have you found a
GUI for it that works on a Mac?
