🔑Aggregate roots serve as transactional boundaries in domain-driven design (DDD).
🔍Identify entities that appear in multiple aggregates and create value objects with IDs to reference them.
🚀Building a visual model of the domain helps identify aggregate boundaries and relationships.
💡Simplifying aggregates reduces concurrency issues and improves flexibility in making changes.
🔄Refactoring the model to establish clear aggregate roots ensures consistency and maintainability.
Why are aggregate roots important in domain-driven design?
—Aggregate roots provide transactional boundaries and enforce consistency within a domain.
How do you determine aggregate roots in a complex domain?
—Analyze entity relationships and identify entities shared by multiple aggregates.
What are the benefits of simplifying aggregates in DDD?
—Simpler aggregates reduce concurrency issues and enable more flexible and efficient changes.
How can visual modeling help in determining aggregate boundaries?
—Visualizing the domain and entity relationships helps identify aggregate roots and their dependencies.
Why should value objects with IDs be used to reference entities across aggregates?
—Using value objects with IDs ensures consistency and clear references between aggregates.
