Can you give examples of situations or projects where it is appropriate to use NoSQL databases?

NoSQL databases are advisable to use in the following situations:

• When data has an unstructured or semi-structured format (e.g., JSON documents).
• When horizontal scaling and high performance are required.
• If a flexible schema that can change frequently is needed.
• For storing large volumes of data with quick access, such as logs, user sessions.
• In projects with a distributed architecture where high availability is important.

Example: In a social media application where users create diverse content (posts, comments, likes), it is convenient to use a document-oriented NoSQL database (e.g., MongoDB) for flexible data storage.
