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

Use one database.

Use one table to hold users and one table to hold quotes.

In between those two tables you have a table that contains information to match users to quotes, this table will hold the rating that a user has given a quote.

This simple design will allow you to store a practically unlimited number of quotes, unlimited users, and you will be able to match up each quote to zero or more users and vice versa.

The table in the middle will contain foreign keys to the user and quote tables.

You might find it helpful to review some database design basics, there are plenty of related questions here on stackoverflow.
