In reality, it is possible to model 80 per cent of any problem with less than 20 per cent of the UML language.
Experience has shown that the most efficient way to learn, and hence master, the UML is to learn just enough to get going and then to simply try out some models of your own. This chapter aims to give just enough information to allow you to get your hands dirty.
There are a great many UML books published that are devoted entirely to the UML and its very rich syntax, see References 1 14 for examples of books concerning UML version 1.x and References 15 17 for examples of books concerning UML version 2.0. This book should be used in conjunction with such books - for example, with the UML reference manual [1].
