Domain-Driven Design is an approach to software development that centers the development on programming a domain model that has a rich understanding of the processes and rules of a domain. One of the downfalls of many software development projects is the misunderstanding of terms, objectives and proposed solutions that are scoped at the beginning of development. But for data-driven devs, the change in perspective isn’t always easy.

Functional Programming and Domain-Driven Design are in some sense orthogonal to one another; DDD makes no hard prescriptions on what language or technology to use. In your software career you may well have encountered many of these ideas already, especially if you are a seasoned developer in an OO language. DDD emphasises separation of concerns with entities such as bounded contexts. “To communicate effectively, the code must be based on the same language used to write the requirements—the same language that the developers speak with each other and with domain experts.” ― Eric Evans, Domain-Driven Design: Tackling Complexity in the Heart of Software So project glossary is about reducing confusion and translation time. Object-oriented domain-driven design (DDD) , aims to develop complex software (iteratively) around a realistic domain model, which both thoroughly captures the domain requirements and is technically feasible for implementation. Design modeling skills. When the ubiquitous language is changed, the mental model is changed and the software is refactored by this new model.
