Question:

Assume that at PVF, each product (described by Product No., Description, and Cost) is composed of at least three components (described by Component No., Description, and Unit of Measure), and components are used to make one or many products (i.e., must be used in at least one product). In addition, assume that components are used to make other components and that raw materials are also considered to be components. In both cases of components being used to make products and components being used to make other components, we need to keep track of how many components go into making something else. Draw an E-R diagram for this situation and place minimum and maximum cardinalities on the diagram.
