openworld 2012 - oracle fusion middleware live application development
DESCRIPTION
In this three our show moderated by Duncan Mills and Chris Muir, the audience could experience the dynamics between three different teams (user interface using ADF, services using SOA Suite, and processes using BPM Suite) that are building an application based on Oracle Fusion Middleware. It's the fourth time Vennster participated in the Live FMW Development sessions after appearances at ODTUG Kaleidoscope, UKOUG, and OBUG. For OpenWorld the team that prepared the sessions consisted of Lucas Jellema, Luc Bors, Aino Andriessen, Guido Schmutz, Lonneke Dikmans, and Ronald van Luttikhuizen. This time we tried a different approach in which we pre-built the application and focused on explaining and demoing it in the first part of the session. After that we made several changes and deployed the improved software components.TRANSCRIPT

First steps
• Define data model
– Canonical model in terms of XML: XSD
– Database: SQL & PL/SQL
Model of Database
First steps
• Define data model – Canonical model in terms of XML: XSD
– Database: SQL & PL/SQL
• Define Interfaces – Service, Operation, Messages (input & output):
WSDL and XSD
• Define Business Events – When and What (payload): EDL and XSD
• Define Process
Defining the business process
• Activities – Automated activities: Services
– Human activities: Tasks (and User Interfaces)
• Process Data
• Flow and logic – Sequence of activities, parallel flows
– Decision points (forks), conditional steps
– Loops, loop backs
• Non-happy day scenarios and exceptions
Agenda
• Defining the Process through BPM(N)
• Designing and Implementing the Services
• Creating the User Interfaces – The back office administration
– The speaker portal
– The conference portal (schedule builder)
• End to End demo
• Revision of process, services and UI – Based on audience suggestions
• Final demo and wrap up
