Data Operations (CRUD) 📝

Mentor's Note: CRUD stands for **C**reate, **R**ead, **U**pdate, and **D**elete. This is what developers do 90% of the time. Once you master this module, you can build the data-engine for any app! 💡


🏗️ What you will learn:

  1. SELECT: How to Read and fetch data.
  2. INSERT: How to Create new records.
  3. UPDATE: How to Modify existing records.
  4. DELETE: How to Remove records safely.
