+# Step 1: Establish the layers
+
+  # Write a list of the layers here
+
+# There will be 3 layers => 1) hash => 2) arrays (values in hash), 3) hash(es) (elements in arrays)  
+# hash = {key: value [{},{},{}]}
+
+########################################################
+# Step 2: Assign a data structure to each layer
+
+  # Copy your list from above, and write what data structure each layer should have
+
+# 1) hash => driver's ids as keys
+# 2) arrays (value of hash) => all ride information for each driver as values 
+# 3) hash(es) (as elements in array) => storing information of each individual ride
+# all_data = {drivers_id: [{ride1_date: ""}, {ride1_cost: 0}, {ride1_rider_id: ""}, {ride1_rating: 0]}
