Explain how you came up with the initial design of your ERD, based on the seed data and reading through the API endpoints	We checked the seed data to verify the fields required and validations for videos and customers. We also went over the Readme and checked that Wave 2 made reference to rentals and then we created the relationships among rental, customer and videos. Created the proper models and migrations.
What would be the Big-O time complexity of your /customers & /videos endpoints? What does the time complexity depend on? Explain your reasoning.	We think that the Time Complexity for customers and videos is log(n) because we have a find_by method that searches for the item in the data base.
What is the Big-O time complexity of the POST /rentals/check-in endpoint? What does the time complexity depend on? Explain your reasoning.	We think that the time complexity for POST /rentals/check-in is log(n) because we have a find_by method that searches for the item in the data base.
Describe a specific set of positive and negative test cases you implemented for a model.	A positive case is for example on video, when it has all the required fields. A negative test case is for example on video model when we set up a new video to be nil. Then all the fields are missing and can not create a video.
Describe a specific set of positive and negative test cases you implemented for a controller.	A positive case is for example when it can renders a 200 code that a check in was successfully done. A negative case is for example when it will respond with "not found" if there is an invalid rental.
Broadly, describe how an API should respond when it handles a request with invalid/erroneous parameters.	If there is invalid parameters, it will respond with a "not found". If there is an erroneous parameters, it will respond with a bad request .
Describe one of your custom model methods and why you chose to wrap that functionality into a method.	Because we wanted to dry our controller methods, we created a custom model method. For example, checkin_update, we wanted to reflect how the available inventory increases and decreases in videos_checked_out_count.
