Overview

The platform organizes learning content in a clear hierarchy. Each level serves a specific purpose: 
Collection (Catalog Organization)
 └── Program (Multi-bundle Learning Path)
      └── Bundle (Discounted Course Package)
           └── Course (Core Learning Unit)
                └── Module (Section/Chapter)
                     └── Lesson (Individual Content)
                          └── Quiz (Assessment)

How Enrollment Works

Students always enroll at the course level, regardless of what they purchase:
  1. Buy a Course → Direct enrollment in that course
  2. Buy a Bundle → System expands via bundle_items → enrolls in each course
  3. Buy a Program → System expands via program_bundles → then each bundle → enrolls in every course
This means a student’s dashboard always shows individual course progress, even if they purchased a program or bundle.
