YES! SUBSCRIBE NOWUnderstanding CRUD: The Notebook Analogy
CRUD is the foundation of almost every software application in existence. To make it super easy for beginners, let's imagine you have a physical Notebook. Managing the pages in that notebook is exactly like managing data in a database!
1. CREATE: Writing a New Page
When you take a blank page and start writing new notes, you are performing a Create operation. In the tech world, this is when you sign up for a new account or post a new status update. You are adding new information to the system.
2. READ: Opening and Reading Your Notes
Whenever you flip through your notebook to find information you wrote earlier, you are performing a Read operation. This is like browsing your social media feed or checking your emails. You aren't changing the data; you are just looking at it.
3. UPDATE: Correcting or Adding to Your Notes
Found a mistake in your notes? You might use an eraser or a pen to fix it. That's an Update. In apps, this happens when you change your profile picture or edit a comment you just made. You are modifying data that already exists.
4. DELETE: Tearing Out a Page
If you no longer need a specific note and decide to tear the page out and throw it away, that is a Delete operation. In software, this is when you remove a photo or deactivate an account. Once deleted, the data is gone.
