| Feature | SQL (Relational) | NoSQL (Non-Relational) | | :--- | :--- | :--- | | | Fixed, rigid. Requires migration. | Dynamic, flexible. | | Scaling | Vertical (buy a bigger server). | Horizontal (buy more cheap servers). | | ACID | Fully compliant (Bank safe). | Mostly "Eventually Consistent" (Tweet safe). | | Joins | Yes (Tables join tables). | No (Denormalized data). | | Best Use | Legacy apps, finance, complex reports. | Real-time apps, big data, rapid prototypes. |
