Motivated by the prevalence of large graph-structured data, there has been a recent proliferation of research on managing, querying and analyzing big graphs. In this talk, I will first survey recent work on graph data management placing a special emphasis on the evolution of graphs over time. Then, I will present our ongoing work on querying the history of evolving graphs and in particular on indexes for historical reachability queries.
