Model Driven Development with Rhapsody By Will Fritz

What is Model Driven Development? A method for producing software quickly, efficiently, and with as little cost as possible. A method for producing software quickly, efficiently, and with as little cost as possible. Based around generating code directly from UML or other modeling languages.

Why use Model Driven Development? MDD allows for easier building and maintenance of complex state machines than direct work with code. MDD allows for easier building and maintenance of complex state machines than direct work with code. Many embedded systems have too many states to keep straight easily through standard development methods Many embedded systems have too many states to keep straight easily through standard development methods

Why use MDD (cont.) With quality MDD tools, systems can be maintained wholly through their state diagrams and other models. With quality MDD tools, systems can be maintained wholly through their state diagrams and other models.

Advantages of MDD There are many advantages to using model driven development. There are many advantages to using model driven development. “By using models, software engineers and other stakeholders are able to argue conceptually about a problem without worrying about syntax or other platform specific issues.”[4] “By using models, software engineers and other stakeholders are able to argue conceptually about a problem without worrying about syntax or other platform specific issues.”[4]

Advantages of MDD (cont.) The added ease of communication can lead to fast design times. The added ease of communication can lead to fast design times.

System independence System can be designed with very little information about final platform. System can be designed with very little information about final platform. MDD emphasizes building system independent models, then applying model transformations to make it fit the target system.

Rhapsody Rhapsody is a MDD tool from Telelogic. Rhapsody is a MDD tool from Telelogic. It currently supports final code generation into Ada, C, C++, and Java. It currently supports final code generation into Ada, C, C++, and Java. It also supports 8, 16, 32, and 64 bit systems. It also supports 8, 16, 32, and 64 bit systems.

Rhapsody (cont.) Rhapsody can run simulations of the designed system. Rhapsody can run simulations of the designed system. It can also run debugging on the target hardware. It can also run debugging on the target hardware. Lastly it includes support for built in requirements and model based testing.

Rhapsody Animator Rhapsody has a debugging tool called the Animator. It shows the current state of the simulation within the diagrams. Rhapsody has a debugging tool called the Animator. It shows the current state of the simulation within the diagrams.

Rhapsody Animator

Target Debugging with Tornado When used for target debugging along with the Tornado IDE Rhapsody is able to show the status of the system in diagrams via the animator while target debugging.
