This series discusses data challenges and solutions in forthcoming large astronomical surveys. It  covers the topic broadly, but with additional focus on Large Synoptic Survey Telescope (LSST) as the largest ground-based survey of the next decade, and the Zwicky Transient Facility (ZTF) the closest time-domain precursor to LSST which is operating today.
