A Conceptual Model For Evolving Graphs Analysis

Currently EURA NOVA is leading two PhD thesis in collaboration with the CODE/WIT Lab of the Université Libre de Bruxelles. Both thesis are supervised by Professor Esteban Zimànyi from ULB and Sabri Skhiri from EURA NOVA.

The goal of my thesis is to build a multidimensional analysis framework on top of NoSQL data, and most importantly Graphs. Recently our paper entitled: An Analytics-Aware Conceptual Model For Evolving Graphs was accepted for presentation on the 15th International Conference on Data Warehousing and Knowledge Discovery – DaWaK 2013. The conference will be held in Prague, Czech Republic from 26 to 29 August 2013. DaWaK is a reference conference on data warehousing bringing together researcher working on BI related topics.

Impossibility of change?

As time goes by and information technologies infrastructures are built, historical decisions accumulate. This accumulation put constraints on architectural options for the future. In other words, the more history you have to manage, the less time you have to make your system progress. And time is money.

Thanks to this point of view, Walt Disney developed unconsciously one of the most efficient innovation process that leads the current success of its well-known company.

One of the biggest news of the month was the announcement and release of Facebook Home. For those of you who haven’t heard about Facebook Home, it’s an Android Launcher replacement. What does it do?

But what Facebook Home shows, is that Android is a very customizable platform that can be tailored to specific needs, even by removing all Google’s services (e.g.: Amazon’s Kindle, Barnes & Noble’s Nook).
