OOW 2012: Data Visualizations with ADF DVT – continuous evolution demonstrated
0One of my favorite areas of ADF is Data Visualization. The rich, interactive and (un)usually attractive components that allow me to spice up an ADF application in a very easy straightforward way have a special appeal. We all know that pictures speak volumes. And that a plain table presents data while a carefully designed visualization presents information and perhaps even a call to action. One of my highlights during Oracle Open World 2012 was – not surprisingly – the presentation by the ADF DVT team – Katrina, Hugh and Jairam – together with Yiannis and Vangelis from PCS in Greece who built a wonderful ADF application for private investment management, with beautiful and very effective data visualizations all over the place.
The story of ADF DVT is one that started probably even before ADF with the BI Beans and before that perhaps even with Oracle Graphics. However, forget about all that history and look to the present and the future. No presentation of Fusion Applications is held without showing off its many data visualizations as a means to turn data into information and information into action. Drawing the user to exceptions, deadlines, alerts, patterns and items to act on is More >
Leveraging HTML 5 Navigator API to show the browser's current location on an ADF Faces 11gR2 Thematic Map component
0This article demonstrates how, through a bit of JavaScript interacting with the HTML 5 Navigator API, some more JavaScript using the ADF Faces Rich Components API and the ADF Faces 11gR2 Thematic Map component, it becomes quite easy to not only learn about the end user’s physical location but to also show that location on a map – and along with it typically the nearest branches of your company.
The page developed in this article will essentially look as is shown in the next figure:
The HTML 5 Navigator API is available in most modern browsers – including Firefox 3.5+, Chrome 5.0+, Safari 5.0+, IE 9, iPhone 3.0+ and Android 2.0+. Note that the user should explicitly allow an application to learn about his or her location – and not get a handle on it just like that.

Map Adventures with Google, Oracle and Spring
In summer 2000 I started in the Field Service development team of Oracle’s eBusiness Suite (http://www.oracle.com/applications/service/srvonl_cont.html). The web form Dispatch Center contains four Java applets. One of them is a map. This map displays the location of the customers and the current position of the field service engineers who synchronize their mobile devices with a central database. The implementation of this map was quite problematic. Especially the performance caused severe headache. In 2005, five years and ten versions later, clicking the tab page of the map still was a receipt to freeze your application… then I saw Google Maps and I nearly fell from my chair. The performance is amazing. But also development work to integrate a map into an application is easy.
