Question #$1$: $[15$ points$]$

Draw a complete ER diagram that represents the following information:

Manufacturers have a name, which we may assume is unique, an address, and a phone

number.

Products have a model number and a type $($e$.$g$.,$ television set$).$ Each product is made by one

manufacturer, and different manufacturers may have different products with the same model

number. However, you may assume that no manufacturer would have two products with the

same model number.

Customers are identified by their unique social security number. They have email addresses

and physical addresses. Several customers may live at the same $($physical$)$ address, but we

assume that no two customers have the same email address.

An order has a unique order number and a date. An order is placed by one customer. For each

order, there are one or more products ordered, and there is a quantity for each product on the

order.
