3 Application Design: A Real-Life Example Prevent trouble before it arises. Put things in order before they exist. The giant pine tree grows from a tiny sprout. The journey of a thousand miles starts from beneath your feet. APPLICATION DESIGN IS A TOPIC SO BROAD that a whole book couldn t fully cover it.The term application design contains merely every single part of development, from data structure layout, flow charts, and entity-relationship diagrams to code layout, documentation, and anything in between. Because it is so important, however, we decided not to exclude it from this book, but instead to tackle a discussion of application design by restricting the topics covered to a hands-on example, namely phpChat.This chapter will give you an in-depth view of this real-time chat server application implemented in PHP,similar to an extended software case study.We hope that you can extract useful information and methods to use when designing your next application.
