Is it unreasonable to assign a MySQL database to each user on my site?

Question

I\'m creating a user-based website. For each user, I\'ll need a few MySQL tables to store different types of information (that is, userInfo, quotesSubmitted, and ratesSubmit

Answer 1

Two problems with many databases (actually many more, but start with these.)

1. You can't use parameters for database names.

2. What will you do whe you make your first change to a table? (Hint: Work X (# databases) ).

And "many tables" suggests you're thinking about tables per user. That's another equally problematic idea.
