Relational databases organize structured data for applications, with deployment and operating choices that can vary across products. Compare deployment model and managed service to consider how each fits your operational approach. Backup retention, high availability, read replicas, and maximum connections offer further criteria for continuity and capacity; JSON data support may also factor into application needs. SQLite, RaimaDB, and MySQL are among the entries, along with Aiven for PostgreSQL and Amazon RDS. Free-plan availability and paid-from pricing let you consider cost alongside these technical and deployment details. Weigh the listed characteristics against the data and operations your application requires.
