These visual demonstrations of Rhapsody guide you through that awkward stage of unfamiliarity with a new application. You'll watch demonstrations that answer these kinds of questions:
- How do I open an existing project and look at diagrams?
- How do I start a new model?
- How do I create a diagram?
These examples also show how easy it is to do some of the more advanced tasks, such as animating a model, which is one of the most important capabilities of Rhapsody.
After you have seen these demonstrations and have replicated the sequences that they show yourself, you will be able to progress easily to the detailed tutorials provided with Rhapsody. Those tutorials lead you step-by-step through topics such as using Rhapsody for code generation and systems engineering modeling.
The examples here are not intended to show all of the capabilities of Rhapsody as a model-driven software development tool, of course.
Downloading and installing the Rational Rhapsody trial
A no charge trial of Rational Rhapsody is available for download here.

Follow the prompts to register for the download of the product. You will have the option to choose to download the Windows or the Linux version of Rational Rhapsody. Also, Rational Rhapsody requires a license key to run. Select to download the evaluation license key. Save the license key file onto your computer. When Rational Rhapsody starts you will be prompted for the location of the license file and browse to where you stored the evaluation key.
Executing a model is the best possible way to test it or to understand its behavior, so that is one of the most important capabilities of Rhapsody. These two examples, one for C/C++ and one for Java, highlight how to use Rhapsody to visualize the interactions between elements in a model. These examples also show how to open an existing model and navigate around it, opening diagrams and examining information stored in the model but not present on the diagrams.
The Rhapsody sample projects also show how to develop a GUI to interact with and test the animated model. In the case of Java, the GUI implementation is also part of the model itself.
The Radio model is provided in the Rhapsody samples in C and C++ flavors.
The "Animating the Radio model" video demonstration shows the following steps for the C++ language:
- Open the Radio model
- View diagrams
- Animate the Radio model
- Run the animated model
- Animate a state chart
- Generate events
- Create an animated sequence diagram
If you want to animate the C version of Radio, open that model and follow the same steps.
The HomeAlarm model is provided in the Java implementation in these Rhapsody samples.
Prerequisite:
If you want to animate the HomeAlarm model yourself, a Java JDK must be installed on your PC.
The "Animating the HomeAlarm model" demonstration shows the following steps:
- Open the HomeAlarm model
- View the diagrams
- Animate the HomeAlarm model
- Run the animated model
- Animate a state chart
- Generate events
- Create an animated sequence diagram
Starting a project and creating diagrams
This example demonstrates how to start your own new project and create a model in it. The "Creating a new model" video shows these steps and describes several new diagrams:
- Create a project
- Create a new package for your model
- Create a use case diagram with four use cases and two actors
- Edit the description of one of the use cases
- Add a comment to the diagram
IBM Rational Rhapsody is a model-driven development environment for systems engineering and software development. The video demonstrations in this Getting Started guide show you how to perform basic tasks, which makes using Rhapsody for the detailed tutorials easier. However, even the basic animation examples provided here show you how Rhapsody can help you understand an unfamiliar model or testing the model at an early stage of development.
