Tài liệu Analysis Patterns

Not long ago, no books were available on object-oriented analysis and design. Now
there are so many that it is impossible for any practitioner to keep up with them all.
Most of these books concentrate on teaching a notation, suggesting a simple process
for modeling, and illustrating it with a few simple examples. Analysis Patterns:
Reusable Object Models is a different kind of book. Instead of focusing on the
process—how to do modeling—it concentrates on the result of the process—the
models themselves.
I am a consultant in object modeling for information systems. Clients ask me
to train staff on modeling and to provide mentoring on projects. Much of my skill
comes from a knowledge of modeling techniques and how to use them. More
important, however, is my experience in actually creating many models and
regularly seeing problems repeat themselves. Frequently I find that many aspects
of a project revisit problems I have faced before. That experience allows me to
reuse models I have built before, improve them, and adapt them to new demands.
Over the last few years, more and more people have also become aware of this
phenomenon. We have realized that the typical methodology books, though
valuable, only present the first step in a learning process that must also capture
the actual things that are built. This realization has flowered into the patterns
movement. This is a varied group of people, representing many different interests
and opinions yet sharing the goal of propagating useful patterns of software
