Table Management 🏗️

Mentor's Note: Tables are the skeleton of your database. If the skeleton is weak, the whole app will fail. This module teaches you how to build and renovate these structures professionally. 💡


🏗️ What you will learn:

  1. CREATE TABLE: Building columns and assigning data types.
  2. ALTER TABLE: Adding new features to an existing structure.
  3. DROP vs TRUNCATE: Knowing when to delete the structure vs just emptying it.
  4. TEMP Tables: Using scratchpads for complex data processing.
