# Step 1: Establish the layers

# Write a list of the layers here
# Layer 1: Drivers - Includes the drivers id and their associated ride information
# Layer 2: Rides - Houses each drivers set of ride information.
# Layer 3: Ride Information - Includes each ride's information (date, cost, rating, rider_id)

########################################################
# Step 2: Assign a data structure to each layer

# Copy your list from above, and write what data structure each layer should have

# Layer 1: Drivers, Data Structure: Hash
# Layer 2: Rides, Data Structure: Array
# Layer 3: Ride Information, Data Structure: Hash

########################################################
# Step 3: Make the data structure!

# Setup the data strcture and manually write in data presented in rides.csv

# stores each driver's information for given rides
