Assume that at Pine Valley Furniture, each product (described by product number, description, and cost) is composed of three components (described by component number, description, and unit of measure), and components are used to make one or many products. 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, we need to keep track of how many components go into making something else. Draw an ERD for this situation, and place minimum and maximum cardinalities on the diagram. Also, draw a data model for this situation using the tool you have been told to use in your course.
