This document identifies technical risks together with suitable mitigation approaches associated with the use of graph database implementations in the planned Army DFS Portal. The document also describes possible technology insertion milestones that may be adopted to enhance the effectiveness of graph database adoption. Rapid prototyping techniques have been applied, as part of the continuing evaluation of alternatives, to stress the implementations of the graph databases chosen for the study. Data collected during those activities will be used to continue maturing the decision process needed to determine the best-of-breed options. The assessments leverage the metrics elaborated in previous reports provided to the sponsor.
