This book documents the UML Designer feature IBM VisualAge
Smalltalk. It explains how you can use the UML Designer feature to
capture and organize requirements and other high-level design
information. With UML Designer, you can capture requirements, design
applications, and document your designs using object-oriented modeling and
analysis techniques. You can create class, sequence, and use case
diagrams using standard Unified Modeling Language (UML) notation.
UML Designer is an integrated part of the VisualAge Smalltalk development
environment. Designs and diagrams are managed as versioned components
alongside the classes and code objects of the actual Smalltalk
implementation. UML Designer prescribes no specific object-oriented
methodology; it supports an evolutionary approach to software
development, where the design undergoes continual revision even after
implementation has begun.
