SQL vs. NoSQL: What’s the difference?

Choosing between SQL and NoSQL databases depends on your project’s scalability, data structure, and query requirements. SQL databases (relational) like MySQL and PostgreSQL use structured schemas and tables, ensuring data consistency and ACID compliance. NoSQL databases (non-relational) like MongoDB and Cassandra offer flexibility, scalability, and faster data retrieval for unstructured or semi-structured data.

If you need structured data with complex queries, choose SQL. If your project requires scalability and high-speed data access, NoSQL is a better fit.

Best Use Cases:

• SQL → Financial systems, e-commerce, CRM platforms.

• NoSQL → Real-time apps, IoT, big data, content management.
