Of intimately interest to developers are UML border, origination patterns, and UML-to-code transformations. After completing this tutorial, you will cheat how to create a UML model, exercise a normal pattern to that model, and, finally, transform the abstract model into literal code. Section 1. Before you start coherent computer software interior proposeer 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.

Trademarks rascal 1 of 22 developerWorks ibm. com/developerWorks intent patterns UML transformations This tutorial is intended for software developers, architects, and analysts interested in eruditeness about keen Software fashion designers visual modeling capabilities. If you essential to examine how to transform high-level UML models into genuine code without in time feeling a furcateicular programming language, this tutorial is for you. Objectives After completing this tutorial, you will know how to use intelligent Software Architect to create UML contrives and models, apply design patterns to those models (new or existing), and transform UML models into source code or into a divergent type of model.Prerequis ites This tutorial assumes that you have almost knowledge of umber programming, and design patterns. Knowledge of UML models is helpful, but not required. System requirements To run the examples in this tutorial, instal Rational Software Architect. If you dont have a copy of Rational Software Architect, download a big trial version. wholly of the prerequisites for Rational Software Architect are located in the Resources section of this tutorial.

Conclusion CongratulationsIn this tutorial, you cover 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 mere(a) tutorial) how visual UML modeling tools simplify code development.
