🧠 Core Philosophy

HBH-DBMS follows a strict hierarchy:

User
 └── Product
      └── Channel
           └── Content

Each layer:

• Is owned by its parent
• Lives inside its parent directory
• Cannot exist independently
• Is managed by a dedicated DB class

This guarantees:

• 🔒 Data integrity
• 🧹 Clean deletes
• ♻️ Easy recovery
