Ecology is about connecting the dots.
one of the goals: interaction webs
Ecology can help use understand & manage big data.
Untangle, sort, link threads, & best of all knit together.
Big Data are not static.
Datasets so large/complex that it becomes difficult to process using traditional data processing applications.

V is for Vampire, and Big Data are all about V (and vampires).

Challenges: capture, curation, context, & complexity-analytics
data are evidence
Useful Big Data illuminate context, connections or interactions
personal solutions
Context: even a single point in a big dataset is informative
personal solutions
Interactions: focus on schema, archive & aggregate datasets
personal solutions
Synthesis: find & use metrics that allow you to connect datasets.

Correlation almost always implies causation.
Correlation does not imply causation.
data = evidencewe need to use synthesis tools

however, large samples do not replace effective designs
