MongoDB

What is MongoDB?

MongoDB is an open-source NoSQL database that stores data as flexible, JSON-like documents. Unlike traditional relational databases, MongoDB does not require a fixed schema, allowing developers to iterate and adapt more quickly. MongoDB is the most popular document database in the world and is used by companies such as Google, Toyota and Forbes.

Why MongoDB is useful

Traditional databases require you to define a strict schema upfront. MongoDB makes it easy to store and modify data without migrations:

• Flexible schema: Add fields when needed, without downtime or migrations
• Horizontally scalable: Automatically distribute data across multiple servers
• Powerful queries: Complex searches, aggregations and full-text search built in
• JSON-native: Data is stored in the format your application already uses

Time savings with MongoDB

MongoDB eliminates the overhead of rigid schema definitions and complex joins. Development is faster because you can store data the way your application needs it.

Hidden features that often go unused

Many teams use MongoDB as a simple key-value store, but its capabilities go much further:

• Time Series Collections: Optimised storage for IoT data, logs and sensor readings.
• Atlas Data Federation: Query data from multiple sources (S3, Atlas) as if it were one database.
• Queryable Encryption: Search encrypted data without decryption — maximum security.
• Atlas Charts: Visualise your data directly from MongoDB without a BI tool.
• Realm Sync: Automatically synchronise data between mobile apps and your database.
• Multi-document ACID transactions: Full transaction support when needed.

Integrations with other tools

MongoDB integrates with many other tools and services:

• Node.js & Python: Native drivers for the most popular programming languages.
• Kubernetes: MongoDB Operator for automatic deployment and management on Kubernetes.
• Zapier & Make: No-code automation with your MongoDB data.
