Visualize with Rational Software Architect Create and transform a UML 2. 0 model into code Skill Level: Introductory Eric Long (elong@us. ibm. com) Software Engineer IBM 21 Mar 2006 Rational Software Architect virtually teems with visual tools to handle a number of development tasks. Of most interest to developers are UML modeling, design patterns, and UML-to-code transformations. After completing this tutorial, you will know how to create a UML model, apply a design pattern to that model, and, finally, transform the abstract model into actual code. Section 1. Before you start

Rational® Software Architect provides developers, architects, and analysts visual tools for a wide variety of software development tasks. This tutorial introduces a few of these powerful visual tools: UML modeling, design patterns, and UML transformations. About this tutorial Learn how to create, edit, and analyze UML models using Rational Software Architect. This tutorial demonstrates the following Rational Software Architect capabilities: • UML modeling Visualize with Rational Software Architect © Copyright IBM Corporation 2006. All rights reserved. Trademarks Page 1 of 22 developerWorks® ibm. com/developerWorks Design patterns • UML transformations This tutorial is intended for software developers, architects, and analysts interested in learning about Rational Software Architect's visual modeling capabilities. If you want to learn how to transform high-level UML models into actual code without even knowing a particular programming language, this tutorial is for you. Objectives After completing this tutorial, you will know how to use Rational Software Architect to create UML projects and models, apply design patterns to those models (new or existing), and transform UML models into source code or into a different type of model.

Prerequisites This tutorial assumes that you have some knowledge of Java™ programming, and design patterns. Knowledge of UML models is helpful, but not required. System requirements To run the examples in this tutorial, install Rational Software Architect. If you don't have a copy of Rational Software Architect, download a free trial version. All of the prerequisites for Rational Software Architect are located in the Resources section of this tutorial. Section 2. Create a UML modeling project To get started, you need to do some initial set up. First, create a UML project and model. Steps

Open the Modeling perspective by selecting Open Perspective > Modeling from the Window menu. Make sure all of your open projects are closed. Select New > Project... from the File menu. Ensure the Show All Wizards box is checked. Expand the Modeling folder. Select UML Project. Figure 1. The New Project window 8. 9. Click Next.

Trademarks Page 5 of 22 developerWorks® ibm. com/developerWorks See, wasn't that easy? Now, on to the more exciting part of the tutorial. Let's build the model using RSA's user-friendly visual tools. Section 3. Model a design pattern

Now it's time to select a design pattern, apply that design pattern to a model, observe all relationships of the pattern, and add attributes and operations to the model. Design patterns in RSA Rational Software Architect comes packaged with support for all of the Gang of Four design patterns. You also have the ability to import and create your own design patterns. Select a design pattern 1. 2. Select Show View > Other... from the Window menu. Expand the Modeling folder and select Pattern Explorer. Figure 5.

Figure 6. The Observer Design Pattern Visualize with Rational Software Architect © Copyright IBM Corporation 2006. All rights reserved. Trademarks Page 7 of 22 developerWorks® ibm. com/developerWorks 6. 7. 8. To learn about the pattern, toggle between the Overview and Short Description tabs at the bottom of the Pattern Explorer view. In the Pattern Explorer view, drag-and-drop Observer onto DesignPattern's blank diagram.

The editor should contain an instance of the Observer Design Pattern that looks like this: Figure 7. Observer Pattern Instance Visualize with Rational Software Architect © Copyright IBM Corporation 2006. All rights reserved. Trademarks Page 8 of 22 ibm. com/developerWorks developerWorks® Apply a design pattern 1. In DesignPattern's editor, hover over ConcreteObserver and select Enter argument name/value.... Figure 8. Enter argument 2. Name the parameter Shopper, then press Enter. The Observer instance now has a concrete observer named Shopper. Let's add a parameter using a different approach.

Your diagram should look similar to this (you might not see all of the relationships... you'll fix that in the next section). Figure 11. Observer instance Observe the design pattern relationships 1. Right-click on any element in the DesignPattern diagram. Visualize with Rational Software Architect © Copyright IBM Corporation 2006. All rights reserved.

Trademarks Page 15 of 22 developerWorks® ibm. com/developerWorks Good work! You have completed your model (a very simple model) and can use Rational Software Architect's tools to transform this model into actual code. Section 4. Transform your model into Java code

Now that you have a completed model within your UML project, you are going to transform that model to actual code. Rational Software Architect supports the Visualize with Rational Software Architect © Copyright IBM Corporation 2006. All rights reserved. Trademarks Page 16 of 22 ibm. com/developerWorks developerWorks® following model-to-code transformations out of the box: • UML -> Java • UML -> EJB • UML -> XSD • UML -> CORBA • UML -> C++ However, if you would like more options, there are built-in tools and wizards that let you create custom transformations in Rational Software Architect.

You are going to transform your existing model into Java. Transform a UML model to Java code 1. In the Model Explorer view, expand DWorksPatternProject. Figure 17. Expanded project 2. 3. In the Model Explorer view, select both Order and Shopper. Right-click on either of the selected objects and select Transform > Run Transformation > UML - Java. Figure 18. Run transformation Visualize with Rational Software Architect © Copyright IBM Corporation 2006. All rights reserved. Trademarks Page 17 of 22 developerWorks® ibm. com/developerWorks 4.

In this tutorial, you covered the creation of a UML project and model, selecting and applying a design pattern to a model, adding and editing attributes and operations to a model, and transforming that model into actual code. You did all of this without even writing a line of code! It is easy to see (even with this simple tutorial) how visual UML modeling tools simplify code development.
