About this tutorial

This tutorial explains how to create validation constraints in IBM® Rational® Systems Developer. This will allow you to detect potential problems in your model early. Problems detected earlier in the product development lifecycle are easier and less expensive to fix.

Objectives

In this tutorial, you learn about creating a validation constraint. To do so, you'll create a UML profile, create a stereotype, and add stereotype attributes. Then, you will prototype your constraint using a pluglet, migrate what you learn to a model validation constraint plugin, and then test that new constraint against a sample model.
