[Cheaper Clicker]

by Team CheaperClicker (Jon Fenn, Connor Mote, Nathan Teeter, and Jacob Winters)

[Introduction]

We will create a proof of concept for a digital classroom quizzing system, similar to kahoot.it or the clickers we have used in class. Students will use their phones to answer questions shown on a main projected display. The main display will receive live updates of student responses via server-sent events.

[Schema]

• QuestionCount int
• CurrentQuestion int in [1, QuestionCount]
• Scores SortedSet names->score (names are reserved by creating an entry in Scores)
• Answers{1..QuestionCount} hash name->answer (as int in [1, 4])
• Question{1..QuestionCount} hash
  • question: json like '{"question": "What is Redis?","answers": ["A NoSQL database","A breed of dog","The best pizza topping","A flavor of ice cream"]}'
  • ans: int in [1, 4]
