MongoDB

Data Model

• MongoDB is a document store. Data is stored as JSON-like (BSON Binary JSON) documents with flexible schema.
• Documents within a collection can have different structures.

Scalability

• Scalable, but scaling can be more complex, especially for write-heavy workloads.
• Sharding is required for horizontal scaling.
• MongoDB prioritizes consistency over availability in its default configuration.
• It offers strong read and write operations consistency and Partition Tolerance.
