OOW 2012: Data Visualizations with ADF DVT – continuous evolution demonstrated

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 >

Suggestion for new type of ADF DVT (Data Visualization): the Delta Graph – to visualize relative changes integrated in a table layout

I may have bored you before with stories about Data Visualization. It is one of my favorite topics. We deal in data. And visualization of data can help to increase the value of the data tremendously. Proper visualization provides quicker insight and reveals the true meaning of the numbers in an instant.

Newspapers frequently use graphics to illustrate the news reported in their articles. My morning paper has a broad palette of ways to represent numbers, trends, aggregates and incidents. It inspires me to mimic in my own toolset: ADF.

The other day, my newspaper printed the next figure that illustrates the changes in circulation for all Dutch newspapers – comparing the 1st quarter of 2011 with one year ago.

I quite like this presentation. It reveals a lot of information in an appealing way. I started wondering it this way of presenting changes would be easy to implement in ADF Faces applications. My first port of call obviously was the ADF DVT (Data Visualization Tags) library. However, it did not seem to offer a graph type that is very close to this presentation. Gauges appeared to come closest, but not quite there. And the inline-display inside table rows is related to spark More >

Use of critical chain projectmanagement in an AMIS project.

3 years ago
by Maurik-Jan Veenman in
  Introduction: At AMIS we have a group of Project Managers who exchange experiences and knowledge with each other. This group read the book of Lawrence P. Leach about Critical Chain Project Management and the group agreed that we would try out the ideas described in this book in our projects. The book takes the ideas from Goldratt (The goal) and transfers them from a Production environment to a Project environment. The results described in the book (projects delivered for far less (up to 40%) than the original time and budget) made us very enthusiastic.   The key issue described in the book is to find the ‘bottleneck resources’ in a project, and make sure that these ones are always at work at full capacity. In case of a System Development Process it usually is a top developer or a functional designer. To make sure they can go on with their work, one has to arrange that there is a buffer of work in the chain before them, so they cannot run out of work. One must also make sure that these scarce resources are working on the things that only they can do, for making the team realize their goal (Project delivered in time and on or below budget), and nothing else.   A second More >
