Domain-Driven Design is not any particular technology or methodology. DDD is a set of rules that enable you to make the right design decisions. This approach allows you to significantly speed up the software design process in an unfamiliar domain.
Domain-driven design (less often, domain-driven design, DDD) is a set of principles and schemes aimed at creating optimal systems of objects. The development process boils down to creating software abstractions called domain models. These models include business logic that links the actual conditions of a product’s application to the code.
The DDD approach is especially useful in situations where the developer is not an expert in the product being developed. For example: a programmer may not know all the areas in which it is required to create software, but with the correct representation of the structure, through a domain-specific approach, he can easily design an application based on key points and knowledge of the work area.
