However, application domains can still talk to each other by passing objects via marshalling by value (unbound objects), marshalling by reference through a proxy (application-domain-bound objects). There is a third type of object called a context-bound object which can be marshalled by reference across domains and also within the context of its ...
The book Domain Driven Design describes some common uses for the above four layers, although its primary focus is the domain layer. [ 11 ] If the application architecture has no explicit distinction between the business layer and the presentation layer (i.e., the presentation layer is considered part of the business layer), then a traditional ...
Domain in the realm of software engineering commonly refers to the subject area on which the application is intended to apply. In other words, during application development, the domain is the "sphere of knowledge and activity around which the application logic revolves." —Andrew Powell-Morse [2] Domain: A sphere of knowledge, influence, or ...
Domain engineering as compared to application engineering. The outputs of each phase of domain engineering feed into both subsequent phases of domain engineering as well as corresponding phases in application engineering. Domain engineering, like application engineering, consists of three primary phases: analysis, design, and implementation.
A domain-specific architecture (DSA) is a programmable computer architecture specifically tailored to operate very efficiently within the confines of a given application domain. The term is often used in contrast to general-purpose architectures, such as CPUs , that are designed to operate on any computer program .
Service reference autonomy (an aspect of loose coupling) The relationship between services is minimized to the level that they are only aware of their existence. Service location transparency (an aspect of loose coupling) Services can be called from anywhere within the network that it is located no matter where it is present. Service longevity

In a service-oriented architecture business software implementation, the enterprise service layer is the highest level of abstraction. [1]Any application programming interface defined at the enterprise service layer can cross domain boundaries; it calls directly the domain device layer, which in turn interacts with the application service layer or the RDBMS Service Layer.
