Compare:vs NoSQL
Databases that scale like magic, but watch out for the surprise bills when the magic gets too real.
Pros
- +Zero infrastructure management—no servers to provision or patch
- +Automatic scaling up and down based on demand, so you only pay for what you use
- +Built-in high availability and backups, reducing operational overhead
Cons
- -Costs can spike unpredictably with sudden traffic surges
- -Limited control over performance tuning and database internals
The old reliable of data storage. Structured, predictable, and sometimes as flexible as a brick wall.
Pros
- +ACID transactions ensure data integrity and reliability
- +SQL provides a powerful, standardized query language
- +Well-defined schemas prevent data chaos and enforce consistency
- +Mature ecosystem with extensive tooling and support
Cons
- -Schema rigidity makes rapid iteration and scaling a pain
- -Performance can tank with complex joins and large datasets
- -Not ideal for unstructured or highly dynamic data
