Comprehension Questions

Question	Response
What is accomplished with raise ArgumentError?	It tells the user that the information inputted is not correct information. It's data validation.
Why do you think we made the .all & .find methods class methods? Why not instance methods?	They are class methods because they can be called without creating an instance of the class.
Think about the relation between Order and Customer. Is this relation one-to-one, one-to-many, or something else? How does that compare to the Solar System project?	It is one-to-many. An order can only have one customer but a customer can have many orders. Customer is to sun as planet is to order.
How is the relation between Order and Customer tracked in the CSV file? How is it tracked in your program? Why might these be different?	In the CSV file it is tracked by customer id number. In the program it is tracked by an object of Customer. They are different because in the program it uses the customer id number to create an instance of Customer to attach to the order.
Did the presence of automated tests change the way you thought about the problem? How?	It did because I had more of a direction to write my code because I wanted to make sure everything passed, not just that it worked.
