OddJava Overview

The core of this challenge is to build a simple REST API using Spring Boot and parse the payload data.
For convenience, we've included common libraries as part of the build, but their use is not required.
Feel free to import any libraries you're comfortable with and resources like Google, StackOverflow, or
documentation when completing this challenge.

Challenges

As health care providers, we're concerned with the moods and stress levels of our patients.
We have a simple H2 database as our data source to generate "Bad Day Reports".

Spring Boot

Build an application using the Spring Boot framework to fetch and save data.
The model and database repositories are already created. You provide the API.
Make improvements as you see fit, but prioritize getting everything up and running first!

Data Parsing

After fetching data, parse the contents to produce "Bad Day Reports"

A Bad Day is defined as when:

  • A user's mood is 1 or 2
  • A user's mood is a 3, but their stress for that same day is a 4 or 5
  • If we don't have mood or stress data for a given day, we'll assume it's neutral (3)

Bad Day Reports

  1. Find which users that had two or more bad days in the week of 2017-05-07 and return

    • Username
    • Number of bad days each patient had for the week

  2. Find the five longest consecutive Bad Day streaks and return for each

    • Username
    • Number of bad days
    • Starting date of that streak

Output Format

  • Nothing fancy, print reports to console
  • Sort all output in decreasing order of bad days

Resource Files

View your H2 database at http://localhost:8080/h2-console

  • username: oddball
  • password: oddball

For reference, resource data files can be found in main/resources/data

users.csv, a CSV file containing fake users
moods.csv, a CSV file containing their moods
stress.csv, a CSV file containing their stress levels
