The video tutorial discusses the implementation of microservice architecture in an ecommerce application, focusing on CQRS, event sourcing, and database patterns. It covers technology choices for microservices, including API gateways and message brokers, and explores options for read and write databases, such as NoSQL and relational databases. The tutorial emphasizes the benefits of CQRS in scaling and performance improvement.

What architectural patterns are applied in the ecommerce application?

• Service-Oriented and Modular

• CQRS, Event Sourcing, and Materialized View

• Client-Server and Peer-to-Peer

• Monolithic and Layered

Which type of database is used for read operations in the CQRS pattern?

• Graph Database

• In-Memory Database

• Non-SQL Database

• Relational Database

Which of the following is a non-SQL database mentioned for read operations?

• PostgreSQL

• SQL Server

• Cassandra

• Oracle

What is a key benefit of using separate read and write databases in CQRS?

• Reduced data consistency

• Increased data redundancy

• Improved query performance

• Simplified database management

What is the advantage of scaling read and write databases independently?

• Simplified architecture

• Higher costs

• Increased complexity

• Improved performance and flexibility
