<P>
One challenge in writing a book on advanced application
development for the Java<FONT SIZE="-2"><SUP>TM</SUP></FONT> platform is to find a project
small enough to write about, while at the same time,
complex enough to warrant advanced programming techniques.
<P>
The project presented in this book is a web-based auction house.
The application is initially written for the Enterprise
JavaBeans<FONT SIZE="-2"><SUP>TM</SUP></FONT> platform. Later chapters expand the core example
described here by adding advanced functionality, improvements, and
alternative solutions to do some of the things you get for free
when you use the Enterprise JavaBeans platform.
<P>
To keep the discussion simple, the example application has only a
basic set of transactions for posting and bidding on auction items.
However, the application scales to handle multiple users, provides
a three-tiered transaction-based environment, controls security,
and integrates legacy-based systems.
This chapter covers how to determine project requirements and
model the application—important steps that should always
come before coding begins.
