Domain-driven design, also known as DDD, focuses on developing software according to a domain built with domain experts' input. In other words, the code structure should reflect the business domain.
To dive deeper into the topic and understand the domain-driven design better, it is good to know some of the terms related to DDD:
- Aggregates – clusters of domain objects that can be treated as single entities.
- Context – the environment in which a word/expression appears specifies its meaning.
- Domain logic is a set of rules impacting the development of the design storage process.
- Entities (Reference Objects) are identifiable objects whose identity is unchanging over time.
- Ubiquitous language – the terminology and terms used in the design and development process by all professionals engaged in a particular project.
- More effective communication between team workers because of the Ubiquitous Language composed by every team member.
- The business goal is central – DDD is business-oriented and helps build a product that fulfills company requirements.
- The roles in the team are clearly defined, and the project goal is settled at the very beginning, which makes the whole development process more efficient.
Domain-driven design helps coordinate software development and business requirements to create a holistic and comprehensive product while not compromising on quality. Layered design is a great solution to manage even more complex projects.
