Architects create application models that are logical views of the business model as they determine how to meet business objectives and requirements. The application models represent the logical view of the architecture for an application.

Architects here are concerned with the overall structure of the application. They decide on the mapping of data management and process steps, they design the interactions between parts of the model in terms of logical messages and sequences, and they determine what data and state should be held by the model. (msdn, 2010).

Each of the elements in the application model requires mapping to elements of real technologies. In this way application models are realized as implementation models. Part of this task is undertaken during conventional development when programmers write detailed business logic as code, but much of the implementation activities are properly classed as framework completion a technique for development where much of the infrastructure of distributed applications and data management is handled by sophisticated frameworks that are extended by custom application logic and declarative control structures. Framework completion shields developers from the intricacies of, for instance, asynchronous message handling, and allows developers with modest skills to make effective contributions to the project. (msdn, 2010).

Architecting and building these models for an organization at each of the different levels is clearly a considerable amount of work and effort. Additionally, the correct definition of these models is critical for an organization. An incorrect architectural model almost always results in serious design or operational issues such as scalability or reliability problems or, in the worst cases, project non-completion and business impact.
