HabiTracker

Track Your Usage and Gather Data Over Time

Project Goals

The application must:

• Maintain a database of habit data
  • Habit Names
  • Event Timestamps (Hour, Minute, Second)
• Before recording an event:
  • Check if the habit exists in the Habits
  • If not, create the habit in the table
  • Record an event in the HabitEntries table

The application should have:

• Selectbox or Inputbox for selecting/adding Habits
• Button to record an event
• A centered heat map for visualizing the user's "Records"
• Ability to visualize:
  • All Habits' data
  • A specific Habit's data

User Interaction Flow:

1. Select or Add a Habit
   • Selectbox: Existing Habit Name
   • Inputbox: New Habit Name (Creates a new habit in the Habits table)
2. Click button to 'Record an Event'
   • Adds entry to database, recording the current timestamp

Database Specifications

Habits Table:

• habit_id (Primary Key Auto-Increment)
• habit_name (e.g., "smoking a half-bowl of weed", "riding a bike for 30 minutes")
• habit_description (optional description of the habit)

HabitEntries Table:

• entry_id (Primary Key Auto-Increment)
• habit_id (Foreign Key referencing Habits table)
• entry_timestamp (Timestamp of when the entry was recorded, down to the second)

Miscellaneous

Example SQL Queries for Database Interactions

• Count the number of times a habit has been used in the past day

SELECT COUNT(*) AS hit_count
FROM HabitEntries
WHERE habit_id = (
    SELECT habit_id
    FROM Habits
    WHERE habit_name = 'Smoke a Bowl'
) AND entry_timestamp BETWEEN '2023-05-07 00:00:00' AND '2023-05-07 23:59:59';

• Retrieve all habit entries, including timestamps

SELECT he.entry_id, h.habit_name, he.entry_timestamp
FROM habit_entries he
INNER JOIN habits h ON he.habit_id = h.habit_id
ORDER BY he.entry_timestamp DESC;
