🔤 C - CRUD 📝

CRUD represents the four core operations performed on data in any application.

In simple words 
If an app works with data 
It is using CRUD in some form 📊

CRUD stands for
• Create ➕ 
• Read 👀 
• Update ✏️ 
• Delete 🗑️ 

Without CRUD ❌ 
No user data 
No posts 
No dashboards 
No real application

🌍 Real World Examples
• Creating an Instagram account ➕ 
• Reading posts on feed 👀 
• Updating profile details ✏️ 
• Deleting a comment 🗑️ 

🔄 CRUD in Backend Flow
Client sends request 🌐 
Server processes logic 🧠 
Database performs operation 🗄️ 
Response sent back to client 📩 

💻 Simple Example using Node and Express

// CREATE
app.post("/users", (req, res) => {
  res.send("User created");
});

// READ
app.get("/users", (req, res) => {
  res.send("Users fetched");
});

// UPDATE
app.put("/users/:id", (req, res) => {
  res.send("User updated");
});

// DELETE
app.delete("/users/:id", (req, res) => {
  res.send("User deleted");
});
