Trivia App
Due: Friday, June 22, 2012 by midnight
Goal: Create a trivia app that presents 25 random multiple choice questions from 11 different
categories. This database pulls the 25 random questions from a TinyWebDB and stores users high scores
to the database.
Learning Objectives
Creativity
LO 1: use of computing tools and techniques to create artifacts.
Abstraction
LO 5: Describe the combination of abstractions used to represent data.
LO 7: Develop an abstraction.
LO 8: Use multiple levels of abstraction in computation.
Algorithms
LO 15: Develop an algorithm.
LO 16: Express an algorithm in a language.
LO 17: Appropriately connect problems and potential algorithmic solutions.
LO 18: Evaluate algorithms analytically and empirically.
Programming
LO 19: Explain how programs implement algorithms.
LO 20: Use abstraction to manage complexity in programs.
LO 21: Evaluate a program for correctness.
LO 22: Develop a correct program.
Computational Features of the App
Uses Randomization to pick the Topic and the Question
o Note: Do not assume a fixed number of questions in each category
Uses the the TinyWebDB you created to pull questions and categories to test your app
Uses the Class Web Database to to test your app if you are having difficulty with your Web
Database
o TinyWebDB - http://everyday-computing123.appspot.com/
Updates the High Scores achieved in your app to the on the Class Web database
o TinyWebDB - http://everyday-computing123.appspot.com/
Uses the Timer feature
Uses conditionals
Uses iteration
Uses Lists or List of list to organize the trivia categories, questions, and answers
Local verse remote storage for real time game play
Minimal Features of your App
-
Creativity – Please add visual and auditory appeal to your app in addition to the questions so
that it doesn’t look drab
Present your user with information about
o how much time they have left to answer a question
o A running tally of the score and the number of questions they’ve completed correctly or
incorrectly. Present to the user where they fit in the high scores already contributed to
the database.
Collaborative Features of the App
-
Each person contributes 16 total questions to the Database
o Each person is required to contribute 10 questions to their assigned category
o Each person is required to contribute 5 questions to their secondary category
o Each person is required to contribute 1 question to the computing category

Features of the Database
-
You can design your own database format given the constraints of TinyWebDB
TinyWebDB allows you to store lists and lists of list.
Please ensure that your database stores the list of questions, possible answers, correct Answer
Suggested format for Storing and Organizing the Data for your Trivia App:

Task
Create a working App that meets the above specified assignment criteria
Describe the features of your App and Add three Screen Shots of your App Interface
and package and upload your app code to your Google Website so that people can see
what your app looks like and download and play it. Explain how your App works and
refer to the screenshots of your code and other representations to support your
explanation.
Explanation of the process you used to design your App being specific about the
creative and functional aspects of your design process. (Please include flowchart or
structural diagrams, sketches, and pseudo code in the description of your App Design).
In particular reflect on the following:
Making decisions about how to represent and store data for your App and
the algorithms they require to implement them (tradeoffs vs advantages)
o Discussion of the level of flexibility you have when you store
information in different ways lists of list verses a single list
o Discussion about local verse remote storage. The issue with this
app is going to be that it is picking the questions in real-time. You
might need to set up a buffer.
