MongoDB vs MySQL: What are the differences?

MongoDB: The database for giant ideas. MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding; MySQL: The world's most popular open source database. The MySQL software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.

MongoDB and MySQL belong to "Databases" category of the tech stack.

"Document-oriented storage", "No sql" and "Ease of use" are the key factors why developers consider MongoDB; whereas "Sql", "Free" and "Easy" are the primary reasons why MySQL is favored.
