If you are a beginner in the world of programming, you might keep hearing the word "CRUD." It sounds complicated, but it is actually the simplest and most important concept you will ever learn for managing data in a database like MySQL.
What Does CRUD Stand For?
CRUD is an acronym for the four basic things you can do with data. Imagine you are managing a list of users in a MySQL database:
- CREATE: This is when you add a new entry. In SQL, we use the
INSERTcommand to add a new person to our list. - READ: This is when you want to look at the data. We use the
SELECTcommand to view who is in our database. - UPDATE: This is when you need to change something. If a user changes their phone number, we use the
UPDATEcommand to fix it. - DELETE: This is when you remove data. If a user leaves, we use the
DELETEcommand to take them off the list.
Why Is It So Important?
Almost every app you use today—Facebook, Amazon, or even your bank—is built on these four operations. Whether you are posting a status (Create) or deleting an old photo (Delete), you are performing CRUD!
Summary for Beginners
Don't let the technical terms scare you. Once you understand that every app is just a way to Create, Read, Update, and Delete data, coding becomes much easier to visualize. In the video above, I break down exactly how this works so you can start building your own database projects.
