MySQL Maximum db size

I am using MySQL Community Server Edition.
Just want to ask what's the maximum size of the db?
Under WinXP OS.

I am no expert in MySql but I think it's limited by OS constraints and/or available storage size.

How About If I have 500,000 persons to record their details
Does MySQL Community Edition can handle that?
Records of person contains only of their personal information.
From name to address up to family members name..
for about 20 facts per person.
