Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. Almost a decade ago, Neo4j took off as a transactional graph database management platform. Just a year after its initial launch, a new, powerful query language called Cypher was introduced to allow expressive, efficient querying and other interactions with the graph data in Neo4j. Today, Neo4j supports graph analytics including implementation of a wide variety of state-of-the-art graph algorithms with custom optimizations for Neo4j’s graph database model. It achieves unmatched performance in scalability, routinely running millions or even billions of nodes and edges.The next natural step for the platform in 2019 is ... Read More

Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. Like a complex system grid or an air-traffic-control map, a graph database is represented as a network of nodes and connections called a labeled property graph. The nodes, which appear as circles or squares, represent entities such as people, products, companies or orders.In Neo4j, the connections between database nodes are called relationships, and those relationships are as important as the nodes they connect. Each relationship is directional and knows its beginning and ending node, and each node knows about all other nodes with which it has an inbound or outbound relationship – ... Read More
