Today's Web 2.0 users increasingly want to perform data-driven tasks that involve collaboration and coordination.
Friends want to make joint travel plans, students want to enroll in courses together, and busy professionals want to
coordinate their schedules. These tasks are surprisingly difficult to support using existing database system abstractions,
as the coordination required is in direct conflict with isolation -- a key property of ACID transactions.

In the Youtopia project at Cornell, we believe that data-driven coordination is so pervasive that it deserves dedicated support
through a clean, declarative abstraction. It is time to move beyond isolation and support declarative, data-driven coordination (D3C) as a
fundamental mode of data management. In this talk, I will introduce entangled queries - a simple yet powerful abstraction and mechanism to
enable D3C. These queries allow users to specify the coordination required, such as "I want to travel on the same flight as my friend".
At runtime, the system performs the coordination ensuring the specifications are met. I will discuss the syntax, semantics and
evaluation of these queries, as well as introducing a range of broader research challenges associated with designing for D3C.
