+# Object Relations Assessment
+
+For this assignment, we'll be working with a Yelp-style domain. We have three models - Restaurant, Customer, and Review.
+For our purposes, a Restaurant has many reviews, a Customer has many reviews, and Restaurant - Customer is a many to many relationship.
+
+If you are not sketching out your domain, and thinking about single source of truth,
+you are doing it wrong :(
+
+## Topics
+
++ Classes vs Instances
++ Variable Scope ( Class, Instance, Local )
++ Object Relationships
++ Arrays and Array Methods
++ Class Methods
+
+## Instructions
+
+Build the following methods on the customer class
++ Customer.all
+  + should return all of the customers
++ Customer.find_by_name(name)
+  + given a string of a full name, returns the first customer whose full name matches
++ Customer.find_all_by_first_name(name)
+  + given a string of a first name, returns an array containing all customers with that first name
++ Customer#add_review
+  + given some content and a restaurant, creates a new review and associates it with that customer and that restaurant
+
+Build out the following methods on the Review class
+
++ Review.all
+  + returns all of the reviews
++ Review#customer
+  + returns the customer for that given review
++ Review#restaurant
+  + returns the restaurant for that given review
+
+Build out the following methods on the restaurant class
+
++ Restaurant.all
+  + returns an array of all restaurants
++ Restaurant.find_by_name(name)
+  + given a string of restaurant name, returns the first restaurant that matches
++ Restaurant#reviews
+  + returns an array of all reviews for that restaurant
++ Restaurant#customers
+  + should return all of the customers who have written reviews of that restaurant.
