Designing a Task Management System
State PatternObserver PatternStrategy
Design a comprehensive task management system that allows users to create, edit, delete, assign, and track tasks with various states, priorities, reminders, and history tracking.
What You'll Build
- The system should let users create new tasks, edit existing tasks, and delete tasks when they are no longer needed.
- Every task should have the following information: Title, Description, Due date, Priority (for example: high, medium, low), Status (such as pending, in progress, or completed).
- Users should be able to assign tasks to other users.
- Users should be able to set reminders so they are notified before a task is due.
- The system should allow users to search and filter tasks, for example by: Priority, Due date, Assigned user, and Status.
