How to migrate 1500 Forms to Apex Tony Andrews
Tony Andrews • UK-based Oracle developer for 20+ years • User of Apex since Project Marvel • Developer at Northgate 2002-2010 • Active on: • tonyandrews.blogspot.com • stackoverflow.com • forums.oracle.com
Aims • 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)
Concerns • Will Apex scale? • Is Apex robust enough for a serious product? • Is Apex good for developers? • Why not Java?!
Challenges • 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
Rich UI • 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
“Dynamic Actions” Defined via data in tables Applied automatically via page 0 region (no developer code)
Rich UI • 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 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.
Reuse Legacy • 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
Consistency (Quality) • Build Standards • Generator • Skeleton pages to copy • Reports to check Apex pages for adherence to standards
Manageability • 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
Apex Resources • Apex on OTN • Apex Forum • Apex Blogs • Apex Development Team
Outcome • Successful replacement system • Satisfied customers • Productive and satisfied developers* • A foundation for developing future applications * well, mostly!
Conclusions • Can Apex be used for large projects? • Is it a good idea? • Would we do it again?
Conclusions • Can Apex be used for large projects? Yes • Is it a good idea? Yes • Would we do it again? Yes – and we have
