Research in mobile and social computing environments is now turning to novel concepts to address the challenge of data processing and analysing. The MWDA2016 workshop addresses issues of data management in mobile and social computing environments with a special focus on data processing. The goal of the workshop is to build a forum for researchers from academy and industry to investigate challenging and innovative research issues in the subject, which combines data analytics within mobile and social environment and to explore creative concepts, theories, innovative technologies and intelligent solutions. We intend this workshop to act as an initial place where people from different areas can find a forum to discuss issues of data management and processing in new and emerging mobile computing environments. Potential participants may come from communities of mobile computing, social computing, or any other areas related to data mining, processing and analysing and etc., in order to present their state-of-the-art progress and visions on the various overlaps across those disciplines.
