Bounded Context Pattern

Introduction

The Bounded Context Pattern is a crucial concept in Domain-Driven Design (DDD) that helps in defining clear boundaries within a system. It establishes a specific context where a particular model is defined and applicable, allowing different teams to work independently without stepping on each other's toes.

Key Concepts

Implementation

To implement the Bounded Context Pattern, follow these steps:

Code Example

Below is an example that illustrates the concept of Bounded Contexts in a microservices architecture.

                // User Service (Bounded Context 1)
                class UserService {
                    public User getUser(String id) {
                        // Logic to retrieve user
                    }
                }

                // Order Service (Bounded Context 2)
                class OrderService {
                    public Order createOrder(User user) {
                        // Logic to create an order for a user
                    }
                }
                

Best Practices

• Clearly define boundaries for each Bounded Context.
• Use Ubiquitous Language consistently across teams.
• Document interactions between Bounded Contexts.
• Keep Bounded Contexts as independent as possible to reduce coupling.
