Tutorial: Creating UML Diagrams with RAD
RAD can generate UML diagrams. There is some “diversity” regarding the symbols and line styles used in UML
diagrams. Although diversity is usually a good thing, when it comes to programming, standards and uniformity are
the rule because they enhance efficiency. If everyone uses the same symbols, then everyone can understand the
diagrams. However, the real world is never so simple. There are a couple reasons for differences. First, there are
disagreements between professionals regarding which is the best way to diagram the classes. Second, there is no
way to enforce a standard. Diagramming is not like the syntax of a programming language (which has to be followed
exactly) for the JVM to work. With that said, we will show (very briefly) RAD's interpretation of a basic UML
diagram. Once you start developing complex applications, you will really appreciate that RAD automatically generates
the UML.
