📝 CRUD in MongoDB Compass: A Beginner-Friendly Guide

---

🔹 1. Introduction

CRUD stands for Create, Read, Update, and Delete, the four basic functions of persistent storage in any database system. In the world of NoSQL databases, MongoDB stands out due to its flexibility and performance, and MongoDB Compass provides a GUI-based interface to interact with databases without writing complex queries.

This blog will walk you through how to perform CRUD operations using MongoDB Compass, making it ideal for beginners or those looking for a visual interface instead of the command line.

🔹 2. Explanation of CRUD

Here’s a quick breakdown of each operation:

Operation	Meaning	Action in MongoDB Compass
Create	Add new documents to a collection	Insert Document
Read	View existing documents	Query or Filter Documents
Update	Modify existing documents	Edit Document or Update Fields
Delete	Remove documents	Delete Document

MongoDB Compass allows you to handle all these operations through a user-friendly GUI—making database management easier for non-programmers too.
