Presentation Overview: This presentation describes how to maintain transitive closure temporally. This advanced TCSQL feature enables the transitive closure maintenance over time. As nodes and connections are added and deleted in a graph, the transitive of all changes is remembered, enabling the ability to ask how a graph looked in the past.
