Domain-Driven Design (DDD) is a powerful approach to software development that focuses on understanding the business domain and using that understanding to drive the design of software systems. One of the key building blocks of DDD is the concept of a Bounded Context. A Bounded Context is a boundary within which a specific domain model applies. It defines a context within which a certain set of terms, concepts and rules make sense. The idea behind Bounded Context is to separate different parts of the system that have different models and different rules. This allows different parts of the system to evolve independently of one another and reduces the complexity of the overall system. By breaking down a system into smaller, more manageable parts, Bounded Contexts make it easier to understand and work with the system. Additionally, Bounded Contexts allow different parts of the system to evolve independently of one another, which can help to ensure that the system remains relevant and useful over time. When creating Bounded Contexts, it’s important to involve domain experts as they are the ones who have the most knowledge and understanding of the business domain. They can help to identify the key concepts, relationships, and rules that govern each part of the system, which can improve the overall quality of the Bounded Contexts. Additionally, it’s important to use a common vocabulary and concepts when creating Bounded Contexts, which can help to create a shared understanding of the domain among developers and domain experts. In practice, Bounded Contexts can be implemented as different modules in your application, each with its own database, services, and interfaces. This makes it easier to change and evolve each module independently, without affecting the other parts of the system.
