2. Microsoft SQL Server: A database from Microsoft that helps businesses manage large amounts of data.
3. PostgreSQL: An open-source database that supports complex queries and is used by developers for different applications.
4. SQLite: A lightweight database often used in mobile apps and small websites.

NoSQL Databases

NoSQL Databases store data differently than traditional databases. They do not use tables and rows. They save data as documents, key-value pairs, or graphs. They handle large amounts of unstructured data like pictures and videos. These databases work well for businesses with big data that changes often.

Characteristics of NoSQL Databases
