Using the above table structure, create a normalized Entity-Relationship Model (ERM). Identify Primary Key(s) and Foreign Key(s) for all the entities, connectivities and/or cardinalities, and relationships between the entities. As for Chen's ERM notation and the normalization, the level should be in Third Normal Form (3NF) and above. [Note: you do notneed to show the normalization process such as the functional dependency diagram.]
