1. Make a design model for the Amazon system with UML Class Diagram.

Use techniques such as visibility, type information, showing navigability (including non-attribute one). For each referenced attribute in the design model provide a role name. Mark a possible, correct order of implementation (provide a number for each class). Map four classes that have association between them into code (e.g., Java, Python, etc., or pseudo-code.). Do not forget to include referenced attributes in the mapping to code. (Lab 8-9).
