APPLICATION EXPRESSOverview
Oracle Application Express (Oracle APEX)Browser Based Application Development
Oracle Application Express (Oracle APEX)Benefits
Rapid Browser Based Development
Point your browser and start developing
Leverage SQL Skills
Build reports and charts using SQL
Self Service Provisioning
Out-of-the-box elastic private cloud service
Runs within Database
Simple to manage, highly scalable
Oracle Application Express (Oracle APEX)Architectural Overview
• Simple 2-Tier Architecture• Pages dynamically rendered using database Metadata• No code generation or file based compilation• Runs Everywhere Oracle Database Runs
ACCESSIBILITY OVERVIEWWhat is it, and why is it important?
What is Web Accessibility?#1 The goal
Equal access
• Perceivable• Operable• Understandable• Robust
Reference: Introduction to Understanding WCAG 2.0
What is Web Accessibility?#2 “The Four Principles of Accessibility”
Why Accessibility is ImportantProcurement and Discrimination Laws
Examples:• Section 508 of the Rehabilitation Act of 1973, amended 1998
(U.S.)• In effect as of 2001• New revision expected sometime in 2013 or 2014
• Mandate 376 (E.U.)• Largely aligned with revised Section 508 for content and timing
• Accessibility for Ontarians with Disabilities Act (Canada)• Americans with Disabilities Act (U.S.)• Disability Discrimination Act, and Equality Act (U.K.)• Twenty-First Century Communications and Video Accessibility
Act (U.S.)The list goes on and on, worldwide…
Why Accessibility is ImportantProcurement and Discrimination Laws, continued
Basic premises of these regulations:• Organizations must develop, procure, maintain or use
E&IT accessible to employees and members of public with disabilities
• Employers must make “reasonable accommodations” unless it poses an “undue hardship”
• Employers must not place an employee at a “substantial disadvantage” in comparison with persons who are not disabled.
• Narrow exceptions for national security, non-availability, undue burden, etc.
Why Accessibility is ImportantIt makes good business sense
• Up to 16% of the population is disabled, either through birth, ageing, illness, or the result of an accident
• Accessible products remove obstacles between a company and its existing or potential customers
• It allows employers to recruit from a broader pool of talent
• Generally improves product for everyone (Universal Design)
And…it’s the Right Thing To Do
The EcosystemMany pieces have to fit together just right
BUILDING FOR ACCESSIBILITYIt’s not just a checklist!
Oracle Accessibility GuidelinesProcess
ACCESSIBILITY AND APEXHow Application Express helps you to address accessibility
Accessibility and Application ExpressHow APEX helps you address accessibility
• The power of themes and templates• Solid templates provide a solid base• Theme 21 underwent accessibility testing for 4.1.1
• Declarative• Exposes declarative attributes that help you define important
properties, eg page titles, form field labels, button labels, table column headers, etc.
• Metadata based• Easier to identify possible violations
Accessibility and Application ExpressHow APEX helps you address accessibility
• Accessibility Modes• Screen Reader• High Contrast
• Adopting modern standards• HTML 5 / WAI-ARIA to help write more semantic code & make richer
content accessible
• Further information• APEX 4.1.1 VPAT (Accessibility conformance statement for APEX)• User Guide > Accessibility in Application Express
DEMONSTRATIONBuilding the application
TESTINGDeveloping a robust testing strategy
TestingDeveloping a robust testing strategy
• What do you test?• Theme testing first (we tested theme 21 in APEX 4.1.1)• Cover primary application flows, and pages representative of
common functionality• Include custom code, e.g. PL/SQL based regions, custom HTML,
etc.• APEX Metadata audits
TestingDeveloping a robust testing strategy
• What types of testing will you do?• Keyboard-only (for users unable to use a mouse, including screen
reader users). (First)• Using automated tools / toolbars (to identify definite failures and
present other mark-up to you in a way that helps you determine compliance). (Second)
• Assistive Technology (AT) testing (such as screen reader testing for users with low vision or who are totally blind). Do this after keyboard-only and using automated tools.
• Colour contrast (for users with low vision, or colour vision deficiency)• Windows High Contrast mode (for users with low vision, or colour
vision deficiency)• User (very important)
TestingDeveloping a robust testing strategy
• Ensure testing is valid• Unplug your mouse for keyboard-only testing.• Turn off your monitor and unplug your mouse for screen reader
testing. You just need a keyboard and speakers!• Engage with users with disabilities
• Raise awareness of standards and testing practices across your team
INTO THE FUTUREWhat’s planned for future versions of Application Express
Into the FutureWhat’s planned for future versions of APEX
• White paper on how to build accessible applications with APEX underway
• Planned removal of modes (bug #14198613)• Further adoption HTML 5, WAI-ARIA & WCAG 2.0• Incorporate jQuery UI 1.9 when released• Metadata auditing• Ongoing framework / theme improvements and fixes• Minimise VPAT exclusions• Community feedback
• APEX 4.2 Early Adopters• Feature Requests
Summary
• Accessibility is not just a checklist• Get your templates and theme right up front• Know the current problems in Application Express• Plan out your testing strategy and include real users• Spread awareness across your team• Watch out for the white paper!
