Graphs are a versatile and dynamic tool used by NASA to solve complex problems in their mission. The organization had been collecting project data since the late 1950s, but accessing it was challenging due to silos between departments and within individual groups, products, and programs. To break down these silos, NASA achieved significant results using Neo4j, a graph database that enabled engineers to identify trends, prevent disasters, and incorporate lessons learned into new projects. The Lessons Learned Database, part of NASA's knowledge management strategy, has already generated significant value by saving at least a year and $2M in research and development. Going forward, the team plans to provide users with the ability to input lessons directly into the database and run text analysis to identify similar documents. This approach allows users to leverage knowledge from the past to improve decision-making and transmit it to the next generation. Graph databases are versatile and can be used by various government agencies to fulfill their missions, and Neo4j helps customers realize the power of graph technology to solve challenging problems.
