NGOSS Shared Information/Data Model
From Wikipedia, the free encyclopedia
The NGOSS Shared Information/Data (SID) model provides the industry with a common vocabulary and set of information/data definitions and relationships used in the definition of NGOSS architectures.
Definition of NGOSS’s common Information Model The SID, as the NGOSS information model, provides an information/data reference model and a common information/data vocabulary from a business as well as a systems perspective. The SID uses UML to formalize the expression of the needs of a particular view.
The SID provides the common language for communicating the concerns of the four major groups of constituents represented by the four NGOSS Views, Business, System, Implementation and Deployment defined in the NGOSS Lifecycle. Used in combination with the eTOM business process and activity descriptions it becomes possible to create a bridge between the business and Information Technology groups within an organization, providing definitions that are understandable by the business, but are also rigorous enough to be used for software development.
The SID model takes inspiration from a wide variety of industry sources, but its principal origins are the AT&T Alliance Information Architecture (ACIA) in the BSS space and the Directory Enabled Networks (DEN NG) model created by John Strassner in the OSS space. Martin Fowler's patterns have also been used in a number of places within the SID.
