| Taking an Oracle ADF Application from Design to Reality |
Learn techniques for decomposing system requirements into a living, breathing Oracle ADF application.
By Chris Muir and Penny Cookson
This multi-part article takes a narrative approach to assist other developers in understanding the mindset and skills required to build an Oracle ADF solution. The article introduces techniques such as storyboarding to capture user requirements, prioritization of requirements to break your problem set into discrete solvable units using a technique known as "MoSCoW," and step-by-step problem decomposition to implement the discrete solutions in ADF Business Components and ADF Faces RC under Oracle JDeveloper 11g.
We will not take readers through step-by-step instructions for creating every single ADF construct. Rather, we presume that readers are familiar with the basics of ADF Business Components—including creating Application Modules, Entity Objects, and View Objects—as well as ADF Faces RC, including the basics of creating JSF pages, page flows, and similar things.
Learn how to use storyboarding techniques to determine requirements, and employ MoSCoW prioritization so you know where to start.
In this section you'll learn how to build the must-have requirements; initially you only need the search fields and a basic search screen.
Learn how to build should-have requirements such as logging of the user's IP address if they accept our terms and conditions and enhanced search capabilities.
Learn how to log all search criteria entered by the user, as well as the number of records returned. This will enable you to monitor how useful the search page is.
Shows how you can add some functionality to prevent malicious access by blocking any IP address that has issued three queries in the last hour but failed to find any results.
