MongoDB

Key concept

  • Documents: In MongoDB, data is stored as BSON documents (binary JSON). A document is similar to a row in a relational database but has a flexible schema.
  • Collections: Groups of documents, similar to tables in relational databases.
  • Databases: Containers for collections.
  • Fields: Key-value pairs within documents.

Use cases

MongoDB is commonly used in projects that require high scalability, flexible schema design, and fast read/write performance

  1. Real-time Analytics & Logging
  • MongoDB: Better for high-speed inserts and unstructured log data.
  • PostgreSQL/MySQL: Can be used but may require extra indexing and partitioning for performance. PostgreSQL has better support for JSONB, making it a solid alternative.
