What Are the Different Types of Databases?

Relational databases use structured tables and SQL, while non-relational databases use flexible data models suited for unstructured or rapidly changing data.

Use a NoSQL database when you need flexibility, horizontal scalability, or need to handle large volumes of unstructured or semi-structured data.

Common types include relational, hierarchical, object oriented, document, key-value, column-oriented, and graph databases.

Consider your data structure, scalability requirements, performance needs, and how frequently your schema is likely to change.

MongoDB is commonly used for modern applications that require flexible schemas, high scalability, and the ability to handle diverse data types.
