Domain-Driven Design (DDD)

Domain-Driven Design (DDD) is an approach to software development that emphasizes collaboration between technical and domain experts to model complex domains effectively. The core concept is to create a shared understanding of the domain through ubiquitous language and to structure the software around the domain model. DDD helps in aligning the software design with business needs and making the system more maintainable and adaptable to changes.

Mapping DDD Concepts to Tracepaper Concepts

DDD Concept Description Tracepaper Concept Description
Entities Objects with a distinct identity Aggregate Document Clustered entities managed as a single unit
Value Objects Objects defined by their attributes Not explicitly mapped N/A
Aggregates Cluster of entities and value objects Aggregates, Behavior Flows Clustered entities with business rules
Repositories Mechanisms for accessing aggregates Abstracted by technical framework Handled through event sourcing
Services Operations that don't belong to entities Automations Logic and operations
Factories Methods for creating aggregates Abstracted by technical framework Handled through event sourcing
Domain Events Events indicating something has happened Events Significant occurrences that trigger changes
Commands Instructions to perform an action Commands Requests for state changes or operations
Bounded Contexts Logical boundaries within the domain Subdomains Defines scope and boundaries of the model

This table shows how the core concepts of Domain-Driven Design are integrated into the Tracepaper modeling tool, facilitating a clear and structured approach to system design.
