Introduction to the notion
The global model of the “heart of the business” is structured in object domains, i.e., in areas which are organized around the principal objects of the described reality (the Enterprise System). This principle is set against a functional domain structure, as used by past methods. The functional approach was shown to bring significant redundancy. A change in approach allows, at least at the design level, a more economical representation, banishing redundancy.
This change brings about a redistribution of the substance of the system, in accordance with a truly new architecture. It will also impact the organization of developments and definition of responsibilities.
