SQL Databases • Structured and table-based. • Follow fixed schema. • Best for complex queries and transactions (ACID). • Examples: MySQL, PostgreSQL, Oracle. NoSQL Databases • Unstructured or semi-structured (document, key-value, graph). • Schema-less. • Scales easily horizontally and handles large data. • Examples: MongoDB, Cassandra.
