Design Microservices Architecture with Patterns and Principles - The Dependency Rule

The video tutorial explains the main principle of clean architecture, focusing on the dependency rule. This rule dictates that code dependencies should only point inwards, meaning that inner layers should not have knowledge of outer layers. The tutorial emphasizes the separation of data formats and DTO objects between layers and provides a visual representation of how dependencies should be structured.

What is the main principle of clean architecture discussed in the video?

• The Polymorphism Rule

• The Encapsulation Rule

• The Inheritance Rule

• The Dependency Rule

According to the dependency rule, how should code dependencies be structured?

• They should be random

• They should point outwards

• They should point inwards

• They should be circular

What should inner layers of code avoid knowing about?

• Data formats of inner layers

• Functions of outer layers

• Classes of inner layers

• Variables of inner layers

What is recommended regarding data formats or DTO objects between levels?

• They should be shared across all levels

• They should stay separate between levels

• They should be merged into one format

• They should be ignored

What is the significance of the arrows in the image mentioned in the video?

• They indicate circular dependencies

• They point outwards to outer layers

• They show random dependencies

• They point inwards to inner layers
