 +=== 4. DELETE - Removing Data ===
 +The DELETE method is used to delete a specified resource from the server. Like PUT, it is idempotent, meaning if you send the same DELETE request multiple times, the result (the resource being deleted) will be the same.
 +
 +**Practical Example:**
 +
 +If a user wants to remove a product from the database, they would issue a DELETE request specifying the resource to be deleted.
 +
 +**Request:**
 +
 +  http
 +  DELETE /products/123
 +
 +**Example URL:**
 +
 +  https://api.example.com/products/123
 +
 +This would delete the product with ID 123 from the server.

 +===== Correlation Between CRUD and HTTP Methods =====
 +CRUD (Create, Read, Update, Delete) refers to the basic operations that can be performed on data in most applications, particularly databases. These operations align with common actions in managing resources. HTTP methods—such as POST, GET, PUT, and DELETE—are used in web development to interact with a server to perform these CRUD operations on web-based resources.
