Design patterns are immensely powerful, but
to build large-scale robust systems, you need more.
Pattern-Oriented Analysis and Design (
POAD) introduces a methodology for "
composing" proven design patterns into
reliable, robust large-scale software systems. Using
POAD, you can quickly build systems that are
far more robust, scalable, and maintainable-using
UML class diagrams as your building blocks.

This book presents an approach to design
soft-ware applications using design patterns. It descri-bes a
POAD methodology that produces
pattern-oriented designs. POAD takes a
structural composition approach to glue patterns at the
high-level design. It uses the notion of constructional design
patterns as design components with interfaces.

POAD is based on the
premise that at some design level, it is sufficient to know
that some patterns are used in the application, and it is not
necessary to overwhelm the designer with the details of the
internal design of each pattern. Wouldn't it be nice to work
at a higher level than class diagrams and yet know that
elements at that level have well-proven class diagrams This
is achieved by POAD
POAD provides logical views to represent the
application design as a composition of patterns and provides
the necessary means to trace participants of those patterns
into the application's final class diagram.
