Model Driven Architecture

Object Management Group™ (OMG) Model Driven Architecture (MDA™) approach provides a set of guidelines for structuring specifications based on platform-independent model. The prime focus of this approach is on the functionality and behavior of the system unlike other architectures that are generally tied to a particular technology.

MDA brings consistency in models of different systems by structuring them into Platform Independent Models (PIMs) and Platform Specific Models (PSMs)

	Platform-Independent Model (PIM)
	Captures the conceptual design without limiting to a particular technology
	Can be expressed using a platform-independent modeling language like UML
	Platform-Specific Model (PSM)
	Includes details of the target platform
	Includes the specification of the mapping between design PIMs and PSMs for a specific technology platform.
OMG's Model Driven Architecture
Features of MDA
	Provides consistent separation
	Consistent relationship
	Shared Standard Mappings
	Improved Portability
	Shared Standard Patterns
	Integrates across computing platform
	Enables Model-Driven Integration
Message from Dr. Richard Soley, OMG Chairman and CEO, "Companies that adopt the Model Driven Architecture (MDA) gain the ultimate in flexibility: the ability to derive code from a stable model as the underlying infrastructure shifts over time. ROI flows from the reuse of application and domain models across the software lifespan." For more details......
