Similarly, graph database vendor Neo4j for several years has run its Graphs4Good program aimed at encouraging users to develop and connect graph-powered projects that address global challenges, from promoting positive social change to upholding democratic values. Graph databases have been around for years – Neo4j launched its first iteration in 2007 – as a way of querying massive data lakes and data warehouses in the growing big data and analytics scene. There are a growing number of graph database vendors and open source projects, from TigerGraph, GraphDB, and Titan. Proponents see graph databases as a more logical way than relational and other database technologies to query huge pools of data, focusing on the idea of connections between data points. It uses nodes – data pieces like people, places or categories – and edges to find relationships within the data.
