I started the day with my own presentation “Like Open Source Forms”, which is one long live demo how to build an ADF Swing application. I then saw a detailed presentation on ADF Taskflow by Edwin Biemond. Some BPEL-infatuated developers tend to use BPEL even for page flows; but with ADF Taskflows, we can now point these people to the right solution.

Paul Dorsey gave his presentation on why all code (including page navigation) ought to be in the database. He told some interesting stories about pure OO projects that failed horribly and concluded that his preferred “thick database” approach resulted in half the development time, half the code, half the database load, ten times the performance and one percent of the network roundtrips compared with the OO approach.

After lunch, I saw John Flack present his project that allows people to locate the nearest substance abuse treatment location and see it on a map. He innovatively combines Google Maps (used for geocoding through a PL/SQL API), Oracle Locator (the SDO_GEOMETRY object type to allow geographical “find nearest” queries) and an ADF Faces user interface with Google Maps embedded.

The last presentation of the day was Carl Backstrom from Oracle who presented some sophisticated AJAX features used in APEX that a Javascript-savvy developer can also use to extend the functionality of APEX applications. And then it was off to the ODTUG party…
