Learn the many design decisions that must be made before starting to build a large Oracle
Application Express (APEX) application for the cloud or enterprise. One of APEX's key strengths
is the fact that it is a Rapid Application Development (RAD) tool. This is also a major
weakness when it tempts developers to start coding too soon. Small applications that consist of
tens of pages can be coded without a lot of design work because they can be re-factored quickly
when design flaws are discovered. Design flaws in large cloud and enterprise applications that
consist of hundreds or thousands of pages are not so easy to re-factor due to the time needed
to redevelop and retest the application not to mention the risk of breaking functionality in
subtle ways. Designing a large application before coding starts is a profitable exercise
because a thoughtful design goes a long way in mitigating cost overruns and schedule slippage
while simultaneously enhancing quality. This book takes into account perspectives from other
non-developer stakeholders such as maintenance developers business analysts testers
technical writers end users and business owners. Overlooking these perspectives is one of the
chief causes of expensive rework late in the development cycle. Oracle Application Express by
Design illustrates APEX design principles by using architecture diagrams screen shots and
explicit code snippets to guide developers through the many design choices and complex
interrelationship issues that must be evaluated before embarking on large APEX projects. This
book: Guides you through important up-front APEX design decisions Helps you to optimize your
design by keeping all stakeholders in mind Explicit code examples show how design impacts cost
schedule and quality What You Will Learn Pick and choose from the list of designs before
coding begins Bake optimal quality into the underlying fabric of an APEX application Think and
design from outside the developer's narrow perspective Optimize APEX application designs to
satisfy multiple stakeholder groups Evaluate design options through hands-on explicit code
examples Define and measure success for large cloud and enterprise APEX applications Who This
Book Is ForAPEX developers and development teams
