What is the difference between SQL and NoSQL databases?

Blog Article

SQL (Structured Query Language) databases are relational databases that store data in tables with predefined schemas. Examples include MySQL, PostgreSQL, and SQLite. They are ideal for applications with complex queries and relationships between data.

NoSQL databases, on the other hand, are non-relational and store data in formats like JSON, key-value pairs, or documents. Examples include MongoDB, Cassandra, and Redis. They are better suited for applications with large volumes of unstructured or semi-structured data.

In full-stack development, the choice between SQL and NoSQL depends on the application’s requirements. SQL databases are preferred for applications with complex transactions and relationships, while NoSQL databases are used for scalability and flexibility in handling diverse data types.
