Getting Hands-On with MongoDB Atlas: CRUD Operations Made Simple
Hey devs

I recently dove into MongoDB Atlas to explore how CRUD operations work in a cloud-hosted NoSQL environment—and I wanted to share a few insights and screenshots from my journey. If you're just getting started with MongoDB or curious about how Atlas simplifies database management, this post is for you!

What I Built
I created a database named CRUD and a collection called students. Using the Atlas UI, I performed basic operations like:

Insert: Added student records with fields like name, age, year, and department.

Query: Filtered documents using operators like $gt, $or, and range queries with $gte and $lte.

Update: Modified fields directly in the UI—super intuitive!

Delete: Flagged documents for deletion with a simple click.

Sample Queries I Used
Here are a few examples of queries I ran:

js
// Find students with student_id greater than 5000
{ "student_id": { "$gt": "5000" } }

// Find students aged either 1 or 3
{ "$or": [ { "age": 1 }, { "age": 3 } ] }

// Find students aged between 1.5 and 7.5
{ "age": { "$gte": 1.5, "$lte": 7.5 } }
Screenshots
