The importance of DDD

We discovered in this chapter that DDD is a powerful methodology that aligns complex software designs with business requirements, particularly beneficial in regulated sectors such as finance, healthcare, and government. These sectors present unique challenges due to stringent regulations, necessitating specific patterns and practices for effective DDD implementation. Practical examples of DDD in such contexts include the modeling of payment systems in financial services, where clear boundaries and responsibilities are crucial. Let’s take a closer look at these examples:

• A DDD approach might involve defining a bounded context for payment processing and isolating it from other subsystems, such as account management or fraud detection. Within this bounded context, domain services, aggregates, entities, and value objects are meticulously designed to encapsulate the business rules and logic pertinent to payments.
• Moreover, context mapping ensures...
