Comprehension Questions

Question	Response
What is accomplished with raise ArgumentError?	You can enforce rules which are set by your code, and if you have a setter method where someone enters data that isn't the kind of data your code is meant to process. With an ArgumentError you can ensure that it won't pass through the constructor.
Why do you think we made the .all & .find methods class methods? Why not instance methods?	It's information that belongs to the overall class of all orders and all customers, so we aren't looking to generate an instance.
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?	One to many, because one individual customer can have many orders. In Solar System, one solar system could have many planets as well.
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, orders have the id of the customer who ordered it. In the all method in my Order class I call on the Customer class to create an instance.
Did the presence of automated tests change the way you thought about the problem? How?	I think so. It gave me small steps to orient myself around when I was looking for what to solve next.
