Assignment 4 – Inspiration Rewards (

Uses:  Multi-Activity, Location Services, Geocoding, Internet, APIs, Images, Camera, Gallery

 

A)    App Highlights:

•       This app allows users within a company or organization to award each other “reward points” (and comments) as a thank you or a commendation for their performance on a task.

•       Users can create a profile for themselves and interact with the other users. Users can later edit/update their profile data

•       Users start with a fixed amount of points that they can award to other users.

•       When a user awards points to another, the point value is deducted from the point total available to give to others.  Once a user is out of points to give, they can no longer add new rewards until their points are renewed.

•       Assume the process of resetting the points-to-award value (and the actual act of rewarding the employee) are out of scope for this project.

•       You will need to create classes to represent the user profiles and the reward assignments.

•       We will be using an Amazon Web Services (AWS) based API to as the “back end” which holds user and reward data.

 

B)    Behavior Use Cases and Activities:  Activity/behavior diagrams follow (in section C)

•       Users can create a new profile (via the Create Profile Activity) with data including a username, password, first & last name, administrator flag, department, position, a short self-summary, and a photo.

Successful account creation logs in the user and displays the Profile Activity. The Create Profile Activity is displayed by clicking a link on the Login Activity. See diagram “a” in the next section.

•       Users login (via the Login Activity) by providing their username and password. A checkbox can be checked to save the credentials so that they are auto-populated whenever the app is started.  See diagram “b” in the next section. Upon login, the User Profile Activity is displayed.

•       The data displayed in the Profile Activity includes first & last name, username, location, awarded point total, department, position, points available to award, a short self-summary, a photo, and a list of awarded points.   See diagram “b” in the next section.

•       From the User Profile Activity, the user can open the Edit Profile Activity via Options Menu. The Edit Profile Activity allows the user to edit the password, administrator flag, first & last name, department, position, the short self-summary, and the photo.  See diagram “c” in the next section.

•       From the User Profile Activity, the user can open the Leaderboard Activity (showing all other users, sorted by awarded point total) via Options Menu. From the Leaderboard Activity, an individual user can be selected and then displayed in the Award Activity. From there, rewards points (and a comment) can be awarded to the selected user. See diagram “d” in the next section.

E) Inspiration Rewards API

Data can be created, read, updated, etc. via the Inspiration Rewards API. The root endpoint for the Inspiration Rewards API is:

Base URL = http://inspirationrewardsapienv.6mmagpm2pv.useast2.elasticbeanstalk.com

Note: the API calls detailed below require you to provide your IIT student ID number (your “A” number) as a part of the data the API required. You MUST you your own student ID. Your student ID number begins with an “A” and is followed by 8 numbers.
