One recurring theme in my articles on ADF has been that end users usually do not care about data. They are interested in getting information that helps them answer questions, make decisions and take actions. Data may be the foundation, but information is to be derived from the data. One way therefore to create applications that are more valuable to our end users is by preprocessing data and turning the data into information – or even into answers, proposed decisions and actions. A powerful way of turning data into information is through data visualization. By presenting data in a format that converts it to readily interpretable information, we help our users a lot. Bar charts, line graphs and other traditional charting formats are one of way visualizing data. The DVT library in ADF Faces goes far beyond traditional charts. It provides components such as the Gantt Chart, the Hierarchy Viewer, the Tree Map, Gauge and the TimeLine that help visualize data in natural, informative and attractive ways. This articles discusses the TimeLine component – introduced in ADF 11gR1 PS6 (18.104.22.168) in the Spring of 2013.
The TimeLine visualizes events against a time axis. It is as simple as that. More >
One 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 >
