How do I Create an ERD for the following?:
A new bicycle store is opening. The owner wants to create her own database to track each bike she buys and sells through her store. Currently, she doesn't plan to sell anything other than bicycles. Because bikes must be registered through the city, each bike has its own unique serial number that tracks each unique bike. For now, the owner only needs to keep track of each bicycle's serial number and name. She only keeps track of customer's last name and email address. She only keeps track of an order's date and total. Create the entity-relationship diagram (ERD) that represents bicycles, customers, and orders. Make sure to add appropriate foreign keys in the diagram (even though it may be implied in a 1-to-many relationship). Every table must have a primary key. Add them where appropriate.
