# Step 1: Establish the layers

  # Write a list of the layers here
  # 1. Information for each driver
  # 2. List of each driver's rides
  # 3. Iinformation about each ride: date, rider ID, cost, and rating
########################################################
# Step 2: Assign a data structure to each layer

  # Copy your list from above, and write what data structure each layer should have
  # HASH >> 1. Information for each driver
  # ARRAY >> 2. List of each driver's rides
  # HASH >> 3. Iinformation about each ride: date, rider ID, cost, and rating
