A big question I get asked when speaking to partners who are developing Oracle ADF, or Webcenter, Apps is how to make it look nice.. Some of the big System Integrators ask me, "Do we have any design patterns/guidelines we can use?". .. Alas website design is a very personal thing and each website will have different requirements and needs, however I am now pleased to say we've just launched "Oracle Fusion Applications Design Patterns" website.
The website is the result of many years of Oracle R&D into user interface design for Fusion applications and features a really cool web app which allows you to visualise the UI components in action.
Although many of the design patterns are related to ADF , its worth noting that ADF took its lead from Oracle Fusion Applications User Interface needs - not the other way around, its just taken us a while to publish these. Coupled together with the dashboard patterns this makes are really cool extra asset for your kit bag
