[edit] 2 Definitive sources for a definition of MDA

OMG MDA site

The current version of the OMG MDA Guide 2.0 is available via that site as below:

MDA 2.0 Word format

MDA 2.0 pdf format

A subset of the Executive Summary from the above guide is:

"MDA provides an approach for deriving value from models and architecture in support of the full life cycle of physical, organizational and I.T. systems."

The Executive summary goes onto elaborate what it means by 'models' and how such models can be used:

"The MDA approach represents and supports everything from requirements to business modeling to technology implementations. The primary feature of MDA which enables us to deal with complexity and derive value from models and modeling is defining the structure, semantics, and notations of models using industry standards – models conforming to these standards are “MDA Models”. MDA models can then be used … (sentences removed-JJ). MDA models can represent systems at any level of abstraction or from different viewpoints, ranging from enterprise architectures to technology implementations. MDA “connects the dots” between these different viewpoints and abstractions."

Example Use Cases include:

1. Part-generation of software component of functionality through transformation, based on models of a) required / defined functionality b) target technology as model and c) transformation model.

2. Part-verification of cross-discipline design versus requirements by generation of correspondence (compliance) model via MDA transformation from two or more design models, model of requirements and transformation (comparison) model.
