High Quality Content by WIKIPEDIA articles! The Anemic Domain Model is a term used to describe the use of a software domain model where the business logic is implemented outside the domain objects.This pattern was first described by Martin Fowler, who considers the practice an anti-pattern. With this pattern, logic is typically implemented in separate classes which transform the state of the domain objects. Fowler calls such external classes transaction scripts. This pattern is a common approach in enterprise Java applications, possibly encouraged by technologies such as early versions of EJB's Entity Beans, as well as in .NET applications following the Three-Layered Services Application architecture where such objects fall into the category of "Business Entities" (although Business Entities can also contain behavior).
