The MDM series of conferences, since its debut in December 1999, has established itself as a prestigious forum for the exchange of innovative and significant research results in mobile data management. The term mobile in MDM has been used from the very beginning in a broad sense to encompass all aspects of mobility - aspects related to wireless, portable and tiny devices. The conference provides unique opportunities for researchers, engineers, practitioners, developers, and users to explore new ideas, techniques, and tools, and to exchange experiences. The 14th IEEE International Conference on Mobile Data Management will be hosted by the vibrant city of Milan, Italy, in the historic palaces of the University of Milan, right in the city center. IEEE MDM 2013 will officially kick-off on Tuesday 4 June with a Keynote address by Christian Jensen titled "Querying the Web with Local Intent", high quality research sessions and tutorials. The next two days will feature other keynotes, a panel titled "Large-Scale Participatory Urban Sensing: A Fad or Reality?", system demonstrations, PhD forum, research and industrial sessions. You will want to arrive early to attend one of the six thematic workshops on Monday 3 June and to attend the welcome cocktail.
