Abstract

Context awareness is an enabling technology of ubiquitous computing aimed at utilizing the location, the time, and other properties that characterize the context of use to select the information that is most appropriate to final users. Although it is widely considered a fundamental ability of modern applications, current database technology does not provide any support to context awareness yet. In this paper, we propose a logical model and an abstract query language as a foundation for context-aware database management systems. The model is a natural extension of the relational model in which contexts are first class citizens and can be described at different levels of granularity. This guarantees a smooth implementation of the approach with current database technology. The query language is a conservative extension of relational algebra where special operators allow the specification of queries over contexts.
