Frequently asked questions

What is MongoDB?

MongoDB is a NoSQL, document-oriented database management system. It stores data in flexible, JSON-like documents, allowing for dynamic and scalable data structures. MongoDB is particularly well-suited for handling large volumes of unstructured or semi-structured data.
How is data organized in MongoDB?

In MongoDB, data is organized into collections, which are similar to tables in relational databases. Each collection contains documents, which are individual records. Documents are JSON-like objects that can have nested structures, providing flexibility in data modeling.
What is the primary advantage of using MongoDB over traditional relational databases?

One of the primary advantages of MongoDB is its flexibility in handling diverse and evolving data structures. Unlike traditional relational databases, MongoDB doesn't require a predefined schema, allowing for dynamic and schema-less data.
How do you query data in MongoDB?

MongoDB uses a query language similar to JSON, called BSON. To query data, you use the find() method.
Explain the concept of sharding in MongoDB.

Sharding in MongoDB involves distributing data across multiple machines to improve performance and scalability. Each shard contains a subset of the data, and MongoDB's sharding architecture allows it to handle large datasets by distributing the load across multiple servers.
