Modeling Complex Infrastructures
MEGA Architecture allows you to further detail system architecture description to take into account systems using resources other than software. For example, a system can comprise radar, pylons, various software elements, a network, people, etc. To define heterogeneous systems, MEGA Architecture provides three diagrams, the Resource Architecture Tree, the Resource Architecture Diagram and the Artifact Assembly Diagram. They enable modeling of system components as well as their communication mode.
The following points are covered here:
