Difference between SQL and NoSQL.
In : BSc IT Subject : Advanced Database Management SystemSQL databases are relational, meaning they store data in structured tables with predefined schemas. They use SQL (Structured Query Language) for defining and manipulating data, and they work well with complex queries and transactions. Examples include MySQL, PostgreSQL, and Oracle. These databases are best suited for applications where data relationships are important, like banking systems or inventory management.
On the other hand, NoSQL databases are non-relational and use flexible data models like document-based, key-value pairs, column-family, or graph formats. They do not require a fixed schema, making them ideal for handling large volumes of unstructured or semi-structured data. Examples include MongoDB, Cassandra, and Redis. NoSQL databases are often used in big data, real-time web applications, and cloud-based systems where scalability and speed are crucial.
SQL is best for structured data and complex transactions , while NoSQL offers flexibility, horizontal scaling, and high performance for diverse data types .
