Within Chapter 3, we started to see how to represent complex data relationships between entities in the business world based on the company requirements. Other than General Hardware Company ER (salesperson, customer, product), you will see a few ER examples at the end of chapter, such as GoodReading Bookstore, World Music Association, Luck Car Rental. In this assignment, you need to draw your own ER diagram similar to these ER diagrams given in the book. Your ER diagram should have - At least one Many-Many binary relationship - At least one One-Many binary relationship - At least four binary entities Each entity should have at least three attributes. You may go with any modality setting based on your company needs. Do not use any intersection data (associative entity) in this assignment. Make sure that your scenario is as much as realistic, i.e., a real-world problem. Remember that you should follow exact notation given in the book and slides. Please use your own company and do not use examples from the book. The online tool at www.draw.io is very helpful to draw ER. You will see how an ER diagram is made with draw.io in this video here. Once you create your ER diagram, upload it D2L.
