7 APEX Day 2011 Ambitions – Presentation (Enquiry) Faster Enquiries User Friendly Technical Jargon Free Business Focussed User Driven Liaise / Consult with End Users –Learn from previous roll-outs –Look at weak areas Flatter Presentation of Data –Quicker Access to Data –Quicker Link to Update

8 APEX Day 2011 Ambitions – Performance (Update) Quicker –Speed of Response –Less Clicks –Multiple Update of data –Enquire / Create / Update –Multi Row Benchmark Existing Application –Address Weak Areas –More Organic Approach Improved Service / Productivity Improved Quality Integrated Workflow / Scheduler

9 APEX Day 2011 Timeline October 2005 Launch Of Prototype at IRRV Conference November 2005 V6 Prototype Installed On Customer Portal December 2005 Management Board Sanctions Version 6 V6 Development Commences Jan - May 2006 Development Continues Consultation Continues User Group Executive Approve Roll-out

14 How to migrate 1500 Forms to Apex Tony Andrews

15 APEX Day 2011 UK-based Oracle developer for 20+ years User of Apex since Project Marvel Developer at Northgate Active on: –tonyandrews.blogspot.com –stackoverflow.com –forums.oracle.com Tony Andrews

16 APEX Day 2011 Update of 1500-module Forms application Preserve large existing database Preserve large existing code base Preserve large existing body of role-based security and navigation metadata Use 20+ developers who know Forms, PL/SQL and the application (but don't know HTML, CSS, Javascript) Aims

17 APEX Day 2011 Will Apex scale? Is Apex robust enough for a serious product? Is Apex good for developers? –Why not Java?! Concerns

18 APEX Day 2011 Migrate 1500 forms quickly, consistently and correctly Some Apex built-in features not useful: –Form region –Tabular form region –Tabs –Validations Requirements for “Rich UI” Management of large Apex project Challenges

19 APEX Day 2011 Reports with “overflow” area Tabular forms over APIs Dynamic hide/show, enable/disable, validation and population of items –In other words, Dynamic Actions! Configurable item, region and report column labels Rich UI

20 APEX Day 2011 Report with Overflow

21 APEX Day 2011 Report with Overflow

22 APEX Day 2011 Report with Overflow

23 APEX Day 2011 Tabular Form

24 APEX Day 2011 Tabular Form

25 APEX Day 2011 Tabular Form

26 APEX Day 2011 Tabular Form

27 APEX Day 2011 Tabular Form

28 APEX Day 2011 Tabular Form

29 APEX Day 2011 Defined via data in tables Applied automatically via page 0 region (no developer code) “Dynamic Actions”

30 APEX Day 2011 Report overflows, tabular forms, “dynamic actions” etc. all defined declaratively via data This data needs to be maintained by the developer, and deployed via version control Creating all this data via SQL Plus scripts or Toad (or SQL Developer) is tiresome Q: What can we do to make the developer's life easier? Rich UI

31 APEX Day 2011 A: Give them an Apex application to maintain the data, with a facility to download all data for a page as a SQL script ready for deployment. Rich UI

32 APEX Day 2011 Forms module definitions in Oracle Designer –Generate first-cut Apex pages and our “metadata” from these Security/navigation data –Render navigation tabs from this –Base page authorisation scheme on this Business Logic APIs –Generate first-cut code to map Apex page to API Reuse Legacy

33 APEX Day 2011 Apex Page Generator

34 APEX Day 2011 Build Standards Generator Skeleton pages to copy Reports to check Apex pages for adherence to standards Consistency (Quality)

35 APEX Day 2011 Many small applications –One per logical business area –Between 5 and 50 pages per app –Assign applications to development teams –Version control export files (app or page) –Version control our metadata Master Application –Common Components, published to other apps: –Templates, Authorisation and authentication schemes –Shortcuts, Application processes Manageability

36 APEX Day 2011 Apex on OTN Apex Forum Apex Blogs Apex Development Team Apex Resources

37 APEX Day 2011 Successful replacement system Satisfied customers Productive and satisfied developers* A foundation for developing future applications * well, mostly! Outcome

38 APEX Day 2011 Can Apex be used for large projects? Is it a good idea? Would we do it again? Conclusions

39 APEX Day 2011 Can Apex be used for large projects? Yes Is it a good idea? Yes Would we do it again? Yes – and we have Conclusions
