Domain-Driven Design Patterns for Regulated Sectors

The Domain-Driven Design (DDD) approach to software design focuses on the creation of accurate models in the business domain. This design approach facilitates a better understanding of the problem domain and enables developers to create more expressive, maintainable, and scalable software solutions that accurately reflect real-world problems and opportunities. However, regulated sectors, such as finance, healthcare, or government, require specific patterns and practices to apply DDD effectively.

This chapter aims to explore DDD patterns that can help product teams deal with the complexity and constraints of regulated domains. Some of the topics covered include identifying and modeling the core domain and subdomains in a regulated context, using bounded contexts and context mapping to separate different models, and ensuring consistency and compliance. We will also look at designing and implementing domain services, aggregates, entities...
