MongoDB vs MySQL

Q: What are the differences between MongoDB and MySQL? A: MySQL is a relational (SQL) database with a fixed schema, tables/rows/columns, strong ACID guarantees, and joins across normalized tables - well suited to structured data with complex relationships. MongoDB is a document-oriented NoSQL database storing flexible, schema-less JSON-like (BSON) documents, favoring horizontal scalability and high write throughput, with eventual/weaker consistency options and no native joins (denormalization/embedding is the norm). Choose MySQL when strong consistency and relational integrity matter; choose MongoDB when schema flexibility and horizontal scale are priorities.
