What is CareDB: a context and preference-aware location-based database system about?

We demonstrate __CareDB__ , a context and preference-aware database system. __CareDB__ provides scalable __personalized__ location-based services to users based on their preferences and current surrounding context. Unlike existing location-based database systems that answer queries based solely on proximity in distance, __CareDB__ considers user preferences and various types of context in determining the answer to location-based queries. To this end, __CareDB__ does not aim to define new location-based queries, instead, it aims to redefine the answer of existing location-based queries. To achieve its goals, __CareDB__ has several distinguishing characteristics that revolve around a generic and extensible preference and context-aware query processing framework that addresses (a) scalable, efficient preference joins, (b) gracefully handling contextual attributes that are expensive to derive, and (c) support for uncertain attributes.
