Domain Driven Design (DDD) is about mapping business domain concepts into software artifacts. Most of the writings and articles on this topic have been based on Eric Evans' book "Domain Driven Design", covering the domain modeling and design aspects mainly from a conceptual and design stand-point. These writings discuss the main elements of DDD such as Entity, Value Object, Service etc or they talk about concepts like Ubiquitous Language, Bounded Context and Anti-Corruption Layer.
