Which of the following architecture domains does the III-RM describe?

The Integrated Information Infrastructure Reference Model (III-RM) primarily deals with the application domain within enterprise architecture. This model is designed to provide a structure that helps organizations understand and manage the complexities of their applications in relation to the business processes they support.

The III-RM focuses on how various applications interact, how they can be integrated to support business functions, and how information flows between them. It outlines a coherent approach to application architecture, emphasizing the importance of applications in delivering business capabilities and services.

While the other architecture domains—business, data, and technology—are essential components of an enterprise architecture framework, the III-RM specifically targets the application side. This means it addresses issues such as application lifecycle, interdependencies, and the relationships among different applications, all of which are critical for effective application management and integration in a coherent enterprise architecture strategy.
