BioScout: a life-science query monitoring system

Scientific data are available through an increasing number of heterogeneous, independently evolving, sources. Although the sources themselves are independently evolving, the data stored in them are not. There exist inherent and intricate relationships between the distributed data-sets and scientists are routinely required to write distributed queries in this setting. Being nonexperts in computer science, the scientists are faced with two major challenges: (i) How to express such distributed queries. This is a non-trivial task, even if we assume that scientists are familiar with query languages like SQL. Such queries can get arbitrarily complex as more sources are considered; (ii) How to efficiently evaluate such distributed queries. An efficient evaluation must account for batches of hundreds (or even thousands) of submitted queries and must optimize all of them as a whole. In this demo, we focus on the biological domain for illustration purposes (our solutions are applicable to other...
