Design Microservices Architecture with Patterns and Principles - NoSQL Databases Types - Document, Key-Value, Graph-Base

The video tutorial provides an overview of different types of NoSQL databases: document, key-value, column-based, and graph-based. Document databases store data in JSON format and are ideal for content management. Key-value databases are suitable for session-oriented applications. Column-based databases offer scalability and are used for big data processing. Graph-based databases are used for storing and navigating relationships, useful in fraud detection and social networks. The tutorial concludes with a brief mention of when to use relational versus NoSQL databases.

What is the structure of graph-based databases, and where are they commonly used?

In what scenarios would you choose NoSQL databases over relational databases?
