MongoDB vs MySQL | UpGuard

**Executive summary:** This article compares MongoDB (a document-oriented NoSQL database) and MySQL (a relational SQL database), outlining differences in data models, query languages, performance, scaling/availability (replication and sharding), typical users, and support options; it concludes MongoDB is better suited to horizontally scalable, high-write or flexible-schema use cases, while MySQL is preferable for ACID-compliant, transaction-heavy workloads with stable schemas.
