If you want to learn how to transform upper-level UML models into actual code without even k right awaying a particular programming language, this tutorial is for you. Objectives After completing this tutorial, you will k promptly how to use sharp software package Architect to create UML projects and models, apply design patterns to those models (new or existing), and transform UML models into denotation code or into a different type of model.Prerequisites This tutorial assumes that you have both(prenominal) knowledge of coffeeâ„¢ programming, and design patterns. Knowledge of UML models is helpful, entirely not required. System requirements To run the examples in this tutorial, raise sagacious Software Architect.

Conclusion Congratulatio ns!In this tutorial, you covered the knowledgeableness 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. At this point, you might want to explore some of the cogitate in the Resources section of this tutorial. Visualize with Rational Software Architect © Copyright IBM Corporation 2006.
