Architecture

NDG and RM-ODP

NERC Data Grid was designed around  RM-ODP (The Reference Model for Open Distributed Processing) framework. Five abstractions or 'viewpoints' each describe the system from a different set of related concerns:

  1. Enterprise Viewpoint
  2. Information Viewpoint
  3. Computational Viewpoint
  4. Engineering Viewpoint
  5. Technology Viewpoint

There are Enterprise and Information Viewpoints to describe the whole of the NDG System. Although a draft Computational Viewpoint was written, for the purposes of the security system, a specific  NDG Security Computational Viewpoint has been written to complement this.
