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 a key advantage of using document databases?

• They are best for storing relational data.

• They offer easy scalability and distribution.

• They store data in a tabular format.

• They require complex JOIN operations.

Which type of NoSQL database is ideal for session-oriented applications?

• Column-based databases

• Graph-based databases

• Document databases

• Key-value databases

What is a primary benefit of column-based databases?

• They are best for social network applications.

• They require less storage space.

• They allow for independent column scalability.

• They store data in JSON format.

In which scenarios are graph-based databases most commonly used?

• Session management

• Fraud detection and social networks

• E-commerce product catalogs

• Content management systems

Which of the following is a popular graph-based database?

• Apache Cassandra

• Redis

• MongoDB

• Neo4j
