EDB: A Multi-master Database for Liquid Multi-device Software

Device shipment trends indicate that the number of web-enabled devices will grow very rapidly. The rapid growth of different types of devices in our daily lives will fundamentally change the expectations on device synchronization. In this paper, we introduce EDB - a database architecture that has been built specifically to support automatic multi-master synchronization between multiple mobile devices with potentially intermittent network connectivity. EDB supports the broader vision of multiple device ownership and liquid software in which applications and services are expected to seamlessly roam from one device or computer to another.
