Problem $2$: Restaurant Review Website $(25$ points$)$

You operate a community website where registered users may post ratings and reviews of area restaurants.

Each registered user has a unique screen name, along with the following details:

$$ First name, last name, address information, email address, and phone number

Your public website displays only the screen name of each registered user. For each restaurant, you want

to store:

$$ Name, address information, phone number, website URL, and category $($e$.$g$.,$steakhouse$,$Chi$-$

nese,$$ etc.$)$

Each review consists of a single registered user$$s opinion of a single restaurant, and includes:

$$ Food quality rating $($scale of $1$ to $5)$

$$ Dinner cost paid per person

$$ Comments $($e$.$g$.,$ long text field$)$

Each registered user may review many restaurants, but only one review per restaurant is allowed
