I've used MySQL for years but never really gave any thought to how exactly my Perl scripts establish their connection to the MySQL server. Do my scripts connect to the MySQL server locally on the same machine, or do the scripts find the MySQL server over the Internet? I'm assuming the former, for simplicity and performance, but I think there's a small chance it's the latter so that remote clients could also have the ability to access the server, and because my MySQL server hostnames are in the form of "mysql.example.com", which suggests accessing via the Internet.
I suppose these aren't mutually exclusive -- my scripts could connect directly when they could, and remote clients could connect over the Internet.
One reason I'm wondering is that I've just learned about SQlite, which runs entirely via an include or module directly inside a script. (It doesn't require a database server.) If my MySQL scripts are being served over the Internet, then SQLite would have an advantage for web apps, since the database results would be served locally rather than having to wait for the Internet.
