Rational Rhapsody: The Basics of Tables- In this video Technical Specialists Andy Lapping takes you through the use of the basic, yet powerful Rhapsody concept of tables. Table cell data is generated in Rhapsody from the information already in the browser. Andy also covers table layouts, structure and properties and then performs some example scenarios.
Ever since the release of Rational Rhapsody 8.0.6, the ability to format code generation has just become BIGGER and BETTER.
Take a look at the list of properties that could be used to format the code as you want.
Every element like Class, Operation, Attribute and other model elements has its own property. The list is quite huge. These properties can be modified at the element level or its owner level. Even the specification and the implementation files have their own set of properties. As can be seen from the screenshot above, Rhapsody has separate section called WriterTemplates (which are defined under the CPP_CG).
Each of this property consists of "[[...]]" containing the code generation extractor keywords within them.
Let's have a look on CPP_CG::WriterTemplates::ClassSpec
The code for the class will be generated in the following way by default:
Homo Sapiens are not the only intelligent ones.. IBM Rational Rhapsody seems to be enhancing its ‘thinking’ capabilities with the introduction of version 8.0.5.
Let us consider you are connecting two ‘actions’ in an Activity diagram with an ObjectFlow. Until the release of 8.0.5, performing the same erroneous step would result in the following error message:
Now in IBM Rational Rhapsody 8.0.5, it automatically understands the error and intention and corrects it by converting the link to a ControlFlow (which happens to be the Intended behaviour). Isn’t that smart?
Similarly, Until the previous release (Rational Rhapsody 8.0.4), you would get the following message when an ‘Action' is connected to an ‘Object Node’ through a ControlFlow:
Here again intelligence of Rational Rhapsody 8.0.5 can be observed, the ControlFlow automatically gets converted to an ObjectFlow when an ‘Action' is connected to an ‘Object Node’:

Over the course of 10 weeks in Q4 2013, developerWorks Rational featured a modeling tip for systems engineers each week from Bruce Douglass. Undeniably, Bruce's 35 years of experience and credentials make him the perfect person to provide this information, and he does so with humor- which makes it all the more fun. We think these are some fabulous hints and tips and hope you find these tips helpful in your daily work as well:
#4 Design patterns reuse proven solutions- In hint #4 of Bruce Douglass' top 10 modeling hints series you'll learn about the importance of leveraging the experience and knowledge of other designers through abstraction or design pattern reuse.
#5 Only 4 (+1) diagrams are required- Your article abstract goes here. Put the main points and key phrases at the beginning of the abstract, because it will be truncated in search results. Make your abstract enticing yet succinct. Aim for three to five sentences that express why the reader would care about the content (motive) and what he or she can gain from reading the content (benefits).
#9 All models are abstractions but some are useful- System engineers have responded to the need for more rigor by adopting the UML and SysML standards. The standards are complex, and don’t provide guidance on how best to apply modeling techniques with these languages to effectively specify requirements and architectures, nor how to use modeling to perform trade studies and the various kinds of analyses required by systems engineering. Dr. Douglass has spent more than 30 years consulting on hundreds of project. He shares his observations and deep experience in this list of his top ten hints for model-based systems engineering.

IBM Rational Rhapsody family provides a collaborative design, development and test environment for systems engineers and software engineers. It uses Systems Modeling Language (SysML) and Unified Modeling Language (UML) to enable rapid requirements analysis and visual, model-based design.
The UML diagrams are views into the underlying semantic system model; each kind of diagram emphasizes some aspect of the model.
Example - Dynamic aspects is represented by behavior diagram - State chart.
Statecharts define the behavior of objects by specifying how they react to events or operations. The reaction can be to perform a transition between states and possibly to execute some actions. When running in animation mode, IBM Rational Rhapsody highlights the transitions between states.
The discussion covers few modeling challenges with state chart using Rational Rhapsody and how to over come those challenges:
1) Evaluation of condition connector in state chart
A scenario where a variable (count) is decremented before the condition connector and is expected to terminate if value of variable is 9 (count==9).
However, on executing you observe that the condition doesn’t take the change in the variable on the transition. Instead it takes the initial value of the variable for comparison.
The work around here is to have an additional dummy state in between to get the desired output.
2) Multicasting with rapid ports in layered structure
Currently, the multicasts of event via rapid ports (ports that have no provided/required interfaces) are supported only from a direct invocation.
Example - One sender object and two receiver objects
Consider a scenario where the event is first sent from the Class A's object(itsA) and then it reaches the Class B's object(itsB), from where it is delegated to its 2 inner parts(itsB1 and itsB2
No multicasting is available on having multi layered structure.
The Workaround is to add an additional state chart and MULITCAST_GEN() macro in class B.
3) Working of Reaction in State
In a single state for a Reactive class, you would expect to continuously print a statement after elapse time of tm (1000). However, upon execution it prints only once instead of continuous timer.
Using a tm (1000) as a trigger for a reaction in state means that 1 second after you enter the state you'll be triggered. It's not a continuous timer.
To restart the timer you have to exit the state and re-enter it. It needs a design change as below.
4) Combining Junction Connector and Condition Connector in a state chart
You would like to have several events from a state and a condition to determine the other state.
You cannot join several transitions into a condition connector neither you can have a transition from a junction connector to a condition connector.
However, you can model to add a dummy state in between that will further evaluate for condition connector.
In this 3-part series, Rational Technical Specialist Ricardo Camacho introduces you to the concept of Systems Engineering and how it is done across an enterprise and across applications via Rational Rhapsody Designer v4.

Stopwatch demo showing model-driven development with IBM Rational Rhapsody in Ada- Ada is a rich high-level language designed for embedded real-time, high integrity and large scale systems development. Progressively, in the Ada 95 and Ada 2005 revisions, it has incorporated more and more Object Oriented (OO) features further increasing its power and richness. During a similar timeframe there has been continued expansion in the use of the industry-standard OMG Unified Modeling Language (UML) for documenting OO designs in C++ and Java. There is arguably no better time for combining the two to help resolve longetivity challenges associated with maintaining Ada software designs. In this video we focus on the core principles and benefits of Model-Driven Development using IBM Rational Rhapsody; including automatically keeping the design and code synchronized at all times and showing its integration with compilers, including AdaCore's GNAT Pro compiler chain. The video uses a Stopwatch example model to highlight the added benefits of higher-level abstractions in UML2 to enable developers to focus on the essential parts of the design and make use of graphical programming techniques to speed up development and capture traceability to requirements. We also showcase Rhapsody in Ada features such as the newer Advanced roundtrip and model-level debugging.
