Data Management Challenges for Social Applications

There are many Database Applications that require users to coordinate and communicate. Friends want to coordinate travel plans, students want to jointly enroll in the same set of courses, and busy professionals want to coordinate their schedules. These tasks are difficult to program using existing abstractions provided by database systems since they all require some type of coordination between users. However, this type of information flow is fundamentally incompatible with classical isolation in database transactions. I will argue that it is time to look beyond isolation towards principled abstractions for Big Data Social. This is joint work with Alan Demers, Nitin Gupta, Christoph Koch, Lucja Kot, Milos Nikolic, and Sudip Roy.
