Pick your favorite internet or other data-intensive application (eg. Facebook, Snapchat, Twitter, Youtube, Uber/Lyft, Amazon, etc.)
1) Design the relational data model for the application.
2) Write at least two SQL queries that the application will need.
3) Design a non-relational data model for the application.
4) Write the same SQL queries using the query language for the chosen non-relational data model (pseudocode is fine for certain query models).
