The Unified Modeling Language (UML) is a third generation method for specifying, visualizing, and documenting an object-oriented system under development. It unifies the three leading object-oriented methods and others to serve as the basis for a common, stable, and expressive object-oriented development notation. As the complexity of software applications increases, so does the developer's need to design and analyze applications before developing them. This practical introduction to UML provides software developers with an overview of this powerful new design notation, and teaches Java programmers to analyse and design object-oriented applications using the UML notation.

• Apply the basics of UML to your applications immediately, without having to wade through voluminous documentation
• Use the simple Internet example as a prototype for developing object-oriented applications of your own
• Follow a real example of an Intranet sales reporting system written in Java that is used to drive explanations throughout the book
• Learn from an example application modeled both by hand and with the use of Popkin Software's SA/Object Architect O-O visual modeling tool.
