NoDB: Efficient query execution on raw data files

Abstract

As data collections become larger and larger, data loading evolves to a major bottleneck. Many applications already avoid using database systems, e.g., scientific data analysis and social networks, due to the complexity and the increased data-to-query time. For such applications data collections keep growing fast, even on a daily basis, and we are already in the era of data deluge where we have much more data than what we can move, store, let alone analyze. Our contribution in this paper is the design and roadmap of a new paradigm in database systems, called NoDB, which do not require data loading while still maintaining the whole feature set of a modern database system. In particular, we sh..
