The amount of data being stored, processed, and analysed in many business, academic and industrial domains, is growing at an exponential rate. How to collect, manage, and analyze data so as to facilitate the transformation of such "Big Data" into actionable knowledge has become a crucial concern. Big data analytics will be the next frontier for advancement of knowledge and innovation, for value creation, and for enhanced decision making process. Its impact on the society as a whole will be far reaching. IEEE SOBDEA 2014 aims to provide a forum for academic and industrial researchers and practicioners to present their latest findings in this highly important field. SOBDEA is also co-located with a number of other important workshops and conferences, which are linked to from this page.
