Are partial observations sufficient to retrieve information about the data that produced them? View-based query processing encompasses many reasoning problems that capture various aspects of this very natural question. This talk is an introduction to view-based query processing. We will define some of the most prominent tasks such as view consistency (how to check that the observation are coherent), certain answers (how to deduce reliable answers from partial data) and rewriting (how to rephrase desired information with respect to available data), and how they relate to each other. No prior knowledge required!
