Definition
Create, Read, Update, and Delete. The four basic functions of persistent storage.
Explain Like I'm New
No matter how complex an application is, it always boils down to CRUD. Facebook? Create a post. Read your feed. Update your profile. Delete a photo. In Node APIs, these directly map to HTTP methods: POST (Create), GET (Read), PUT/PATCH (Update), DELETE (Delete).
Real World Example
Writing the four core Mongoose queries: `Model.create()`, `Model.find()`, `Model.findByIdAndUpdate()`, and `Model.findByIdAndDelete()`.
