Question

Consider the following description below:

A furniture company produces several products for sale.

Each product (described by Product ID, name and price) is made up of one or more components (described by Component ID and name). A component can be used in one or more products.

A component can be a simple component or compound component. A compound component is one that contains one or more other components (which can be simple or compound components). A simple component is indivisible, i.e. it cannot contain other components.

The quantity of a component in a product must be recorded. For example, if product P contains 2 physical units of component C, the quantity 2 must be recorded. Similarly, if component C1 contain 4 physical unit of component C2, the quantity 4 must be recorded.
