This document summarizes Oliver Busse's presentation on using Graph databases in XPages applications. It introduces Graph databases and their terminology like vertices and edges. It describes how GraphNSF, a Graph database implementation in Domino, stores vertices and edges as documents in NSF files. It provides examples of creating vertices and edges programmatically and adding metadata to existing data using a graph structure. It concludes with a live demo of a GraphNSF implementation in an XPages application.
