What is Model Driven What is Model Driven Development?Development?

A method for producing software quickly, A method for producing software quickly, efficiently, and with as little cost as efficiently, and with as little cost as possible.possible.

Based around generating code directly Based around generating code directly from UML or other modeling languages.from UML or other modeling languages.

Why use Model Driven Why use Model Driven Development?Development?

MDD allows for easier building and MDD allows for easier building and maintenance of complex state machines maintenance of complex state machines than direct work with code.than direct work with code.

With quality MDD tools, systems can be With quality MDD tools, systems can be maintained wholly through their state maintained wholly through their state diagrams and other models.diagrams and other models.

Advantages of MDDAdvantages of MDD

There are many advantages to using There are many advantages to using model driven development.model driven development.

““By using models, software engineers and By using models, software engineers and other stakeholders are able to argue other stakeholders are able to argue conceptually about a problem without conceptually about a problem without worrying about syntax or other platform worrying about syntax or other platform specific issues.”[4] specific issues.”[4]
