Eating their own dog food

This gives us confidence

What About the Rest of Us?Smart software vendors have recognised the strategic shift to ADF and acted

CALLISTASmart software vendors have recognised the strategic shift to ADF and acted

Callista have been developing on the JDev platform for some years, starting with 10gBegan training/prototyping in 2006Ahead of the curve for the Middleware platform Significant investment in defining best practice technical architecture for the productTALENT2Smart software vendors have recognised the strategic shift to ADF and acted

Talent2 with their Alesco software have been developing on the JDev platform for some years, starting with 10gAhead of the curve for the Middleware platform Significant investment in defining best practice technical architecture for the productWhat About the Rest of Us?Custom developments vary in size and complexity

Recommendation

Start small and learnThen build a well architected and practical solutionForms ModernisationSage has been working with the Department of Finance on their RCIS modernisation project Large numbers of Oracle Forms programsOriginally Oracle Forms 4.5 & Reports 2.5Successfully upgraded through/up to 10gBy 2010 grew to ~800 Forms & ~200 ReportsInternal and External applicationsLarge investment in traditional Forms skillsSignificant business code in PL/SQL packages.Net vs ADF - Title FightDTF pre-selected potential platforms.Net & ADF main contendersA number of PoC challenges were devised

Prior to trial, ADF was considered poor cousinBut ADF was chosen as a clear winnerMain Perceived Benefits of ADF?Database centricDeclarativeJavaService Oriented Development (task flows)Task flows -> ReuseRich Enterprise Application (Web 2.0(ish))Suitable for both public/internal appsSingle WLS platformFuture proofing: Oracles strategic platform

Redesign and Build in Jdeveloper ADF

http://www.oracle.com/technetwork/developer-tools/jdev/fhog-uin-157767.pdfIssues for Any New Jdeveloper ADF Project

For Business Analysts determining requirementsTake advantage of new interface styles and functionalityConsider business improvementsThink in terms of business servicesAvoid the temptation to think in terms of Oracle Forms

For Business Analysts determining requirementsLots of contentMultiple tabs

All strung together in a network

Oracle Forms

For Business Analysts determining requirementsWell designed workflows

Jdeveloper ADF

For Business Analysts determining requirementsSimple, cleaner content on data entry pagesJdeveloper ADF

For Business Analysts determining requirementsSummary screens can have lots of contentUse UI components like AccordionsJdeveloper ADF

For Business Analysts determining requirementsMore sophisticated searching options than FormsJdeveloper ADF

For Business Analysts determining requirementsAre you going to use the UI Shell?Jdeveloper ADF

Issues for Any New Jdeveloper ADF ProjectFor Technical Architects and DesignersA high level of skills is requiredFor any but a very simple application the following are critical:Managing reuseManaging deploymentManaging versionsStandards

Issues for Any New Jdeveloper ADF ProjectFor DevelopersThe learning curve is steepThere are lots of resources on OTN/blogs etc do not reinvent the wheelDo not fight the product try to go with what it does wellReuse existing PL/SQL code

Issues for Any New Jdeveloper ADF ProjectFor Project ManagersAllow plenty of time for technical architecture designSkills may be in short supplyTraditional Oracle developers will require significant time to transitionInnovative requirements analysis can lead to business agilityIt will take longer than you think (but what project doesnt)




Chris MuirPenny Cookson A Technical Overview

http://www.oracle.com/us/support/library/lifetime-support-middleware-069163.pdfCo-existence

Legacy Forms applications will remain an important part of many solutions

Upgrade

Interoperate

53Integration With Legacy Forms

For large applications progressive replacement approach is likelyFull integration - OraFormFaces

Specific integration points minimises Forms changes

No integration only possible if independent chunks of the application can be identifiedOracle Fusion Middleware

Chris MuirPenny Cookson The Power of ReuseHow Oracles ADF makesweb development productive again

AgendaPart 1Making use of ReusePart 2SkinsPart 3Page TemplatesPart 4Declarative ComponentsPart 5The Killer Reuse FeaturePart 1 Making use of ReuseThe old computing rules are still the most important

Easier to designEasier to readEasier to comprehendEasier to testEasier to debugEasier to changeEasier to reuseAxiom: any duplicated code should become a module= Reduced system cost+ Increased developer productivity+ Less time to market+ Increased business satisfaction

Employees PkggetNameupdateAddresspayDepartments PkgCountries PkgWebPage?Part 2 - Skins

Defines basic application look & feelAn abstracted named extension of CSS filesNo different from other web solutions, except:All ADF components support skin styleclassesAt runtime the user can switch skins

As of 11.1.2.0.0No need to learn the tricky CSSWill generate a lot for you

102Part 3 Page TemplatesDefine a single common page templateContains:Static content shared by all consumersDynamic content injected by each consumerAttributesDefine attributes:Values passed from consumerDisplayed by page templateReuseBy 1 or more pages or fragmentsBy 1 or more applications

Declarative components Define a component groupReuse throughout your applicationParameter drivenConsistent look & feel & behaviourCan be shared across applications too

Part 5 The Killer Reuse FeatureThese features are goodbut theyre not revolutionary in web design

Heres the feature that sets ADF above all other web frameworks
