SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps in designing secure and maintainable domain models by emphasizing domain language, clear boundaries, and safety checks.

Core Features & Use Cases

Domain Language Emphasis: Encourages the use of domain language in design decisions.
Clear Boundaries: Ensures that types and operations are well-defined and do not leak across layers.
Safety Checks: Promotes the inclusion of safety checks within the domain model to prevent invalid states.
Use Case: When designing a domain model for a banking application, this Skill helps ensure that the model accounts for all possible valid and invalid states, maintaining data integrity and security.

Quick Start

Use the domain-design-safety-discipline skill to review the domain model of your banking application and ensure it adheres to the principles of clear boundaries and domain language.

FAQPage Schema

How do I design a domain model that prevents invalid states and maintains data integrity?▼

To design secure domain models, emphasize domain language, establish clear boundaries for types and operations, and implement safety checks to prevent invalid states. This maintains data integrity by ensuring operations do not leak across architectural layers.

Why does my domain model leak types and operations across application layers?▼

Domain models leak types when clear boundaries are not established. Applying domain-driven design principles ensures types and operations are well-defined, preventing leakage and maintaining structural integrity across software layers.

What is the role of domain language in maintaining secure domain boundaries?▼

Domain language ensures design decisions accurately reflect business logic, which helps establish clear boundaries and safety checks. Using precise domain language prevents ambiguous states and maintains data integrity within the model.

How to add safety checks to a banking application domain model?▼

Add safety checks to a banking application domain model by defining valid and invalid states explicitly. Using domain-driven design principles ensures the model enforces data integrity and prevents unauthorized state transitions.

Do I need to understand object-oriented programming to apply domain-driven design safety checks?▼

Yes, understanding object-oriented programming and domain-driven design principles is required to implement safety checks. This prerequisite knowledge is necessary to define clear boundaries and types within the domain model.

When should I not use strict boundaries in domain model design?▼

Strict boundaries in domain model design may not be necessary for simple CRUD applications where data integrity and invalid state prevention are not critical. It is best applied in complex software development scenarios requiring high security.
