The Importance of Being Explicit in Designing Systems

TLDRDesigning systems based solely on data or entities can lead to complex and difficult-to-change systems. It is crucial to also consider the behaviors and functionalities of the system and be explicit about them. Focusing on entities alone can result in a CRUD-based system, while understanding behaviors allows for more specific and effective designs.

Q&A

What happens if systems are designed solely based on entities?

Designing systems solely based on entities can result in complex and difficult-to-change systems. It can lead to a CRUD-based system that lacks specificity and may not effectively capture the behaviors and functionalities of the system.

Why is it important to be explicit about system behaviors?

Being explicit about system behaviors allows for more effective designs. It helps capture the specific actions and functionalities that need to be performed within the system, leading to better understanding and communication among team members.

How can explicit design improve system scalability?

Explicit design improves system scalability by enabling better separation of concerns and encapsulation of functionality. By understanding the specific behaviors and functionalities of the system, components can be designed to scale independently and handle specific tasks efficiently.

What are the potential challenges of implicit design?

Implicit design, where behaviors and functionalities are not explicitly captured, can lead to confusion and misunderstanding among team members. It can make it difficult to make changes to the system and can result in hidden dependencies and technical debt.

How can event-driven designs benefit from explicit system behaviors?

Event-driven designs rely on explicit system behaviors to publish events and notify other components of specific actions. By capturing behaviors explicitly, event-driven architectures can effectively communicate and react to system events, leading to more scalable and resilient systems.
