Architecture Layer: Information

Requirements Realization Viewpoint : Archimate

Concerns: Architecture strategy and tactics, motivation
Purpose: Designing, deciding, informing
Scope: Motivation

The requirements realization viewpoint allows the designer to model the realization of requirements by the core elements, such as business actors, business services, business processes, application services, application components, etc. Typically, the requirements result from the goal refinement viewpoint.

In addition, this viewpoint can be used to refine requirements into more detailed requirements. The aggregation relationship is used for this purpose.

Information Structure Viewpoint : Archimate

Concerns: Structure and dependencies of the used data and information, consistency and completeness
Purpose: Designing
Scope: Multiple layer/Single aspect

The information structure viewpoint is comparable to the traditional information models created in the development of almost any information system. It shows the structure of the information used in the enterprise or in a specific business process or application, in terms of data types or (object-oriented) class structures. Furthermore, it may show how the information at the business level is represented at the application level in the form of the data structures used there, and how these are then mapped onto the underlying technology infrastructure; e.g., by means of a database schema.
