Is MongoDB frontend or backend?

MongoDB is a backend technology. It is a database management system used to store, retrieve, and manage data for applications. It operates on the server side and is a part of the backend infrastructure.

Why MongoDB Is Backend

1. Data Storage: MongoDB stores data in JSON-like documents, which are used by backend servers to manage and process application data.
2. Server-Side Operations: It handles queries, indexing, and transactions, all of which are backend processes.
3. Integration with Backend Technologies: MongoDB is typically paired with backend frameworks like Node.js, Python (Django, Flask), or Java (Spring) for building server-side applications.

Role in Full-Stack Applications

• Backend: MongoDB is responsible for storing and serving data to the frontend through APIs built using backend frameworks.
• Frontend: While the frontend interacts with MongoDB indirectly via APIs, MongoDB itself is not a frontend technology.

Example Use Case

In a full-stack application:

1. Frontend: React or Angular sends a request for data.
2. Backend: Node.js or Python retrieves the requested data from MongoDB.
3. Database (MongoDB): Responds to the backend with the relevant data.

MongoDB is entirely a backend tool, critical for managing and serving data in web and mobile applications.
