Design Microservices Architecture with Patterns and Principles - Relational and NoSQL Databases - Document, Key-Value, G

The video tutorial discusses the differences between relational and NoSQL databases, focusing on their implementation in microservice architectures. It explains the structure, advantages, and limitations of relational databases, including their use of SQL and ACID compliance. The tutorial also covers NoSQL databases, highlighting their scalability and ease of use, while noting the lack of ACID guarantees. The video concludes with a brief mention of different NoSQL data models.

What are the two main types of databases commonly used in microservice architectures?

• Key-Value and Column

• Document and Graph

• SQL and Neavsql

• Relational and NoSQL

Which principle ensures that a database transaction is reliable in relational databases?

• CRUD

• CAP

• ACID

• BASE

What is a primary disadvantage of relational databases in microservices?

• Lack of ACID compliance

• Inability to scale horizontally

• Complex data models

• High cost of implementation

Which of the following is NOT a type of NoSQL database?

• Column-based

• Graph-based

• Table-based

• Document-based

What is a major drawback of NoSQL databases compared to relational databases?

• High cost of implementation

• No ACID guarantees

• Complex data models
