Description: Domain-Driven Design (DDD) is an approach to software development that focuses on the core domain and its logic. This approach seeks to create a conceptual model that reflects the reality of the business, facilitating communication between developers and domain experts. In DDD, a deep understanding of the domain is prioritized, allowing development teams to build solutions that closely align with business needs. Key characteristics of DDD include the identification of ‘bounded contexts’, where the boundaries of the model are defined, avoiding ambiguity in terminology. Additionally, DDD promotes the use of a ubiquitous language, which is a common language shared by all team members, improving collaboration and reducing misunderstandings. This approach also encourages the creation of entities, aggregates, and services that encapsulate domain logic, allowing for a cleaner and more maintainable architecture. In summary, Domain-Driven Design is a methodology that seeks to align software development with business goals and processes, ensuring that the final solution is relevant and effective.
History: The concept of Domain-Driven Design was popularized by Eric Evans in his book ‘Domain-Driven Design: Tackling Complexity in the Heart of Software’, published in 2003. Since then, it has evolved and been integrated into various agile development practices and modern architectures, such as microservices.
Uses: Domain-Driven Design is primarily used in complex software projects where business logic is intricate and requires deep understanding. It is common in enterprise applications, management systems, and platforms that need to adapt to frequent changes in the domain.
Examples: An example of DDD in action is the development of an order management system, where bounded contexts for ‘customers’, ‘products’, and ‘orders’ are clearly defined, each with its own model and business logic. Another example is the use of DDD in e-commerce platforms, where seamless integration between different domains such as inventory, payments, and shipping is required.
