See Our Customers Delivering Value for the World’s Largest Organizations Customer Story Graph Developers Helped NASA Get to Mars Ahead of Schedule Locked in decades of NASA project data is knowledge – but accessing that information was challenging due to silos between departments and individual groups. NASA leveraged a Neo4j knowledge graph to create their Lessons Learned Database to collect, store, and share information. The Lessons Learned Database has generated significant value for NASA. As David Meza, Chief Knowledge Architect at NASA put it: "This has saved us at least a year and over $2 million in research and development toward our Mission to Mars planning."

Learn more about AuraDB Fully automated, with zero administration On-demand scalability without restarting Always-on, secure, durable, and reliable Simple, consumption-based, predictable pricing CYPHER: THE GRAPH QUERY LANGUAGE No More Complex Joins Cypher is a powerful, intuitive, graph-optimized query language that understands, and takes advantage of, data connections. It’s user-friendly, easy to learn, and follows connections – in any direction – to reveal previously unknown relationships and clusters. When trying to find patterns or insights within data, Cypher queries are much simpler and easier to write than massive SQL joins. Since Neo4j doesn’t have tables, there are no joins to worry about. Compare the Cypher query at the left with its equivalent in SQL.

Neo4j supports GraphQL and drivers for .Net, Java, Node.js, Python, and more. Our community of contributors provide many more drivers, including PHP, Ruby, R. Erlang, and Clojure. Learn more about Drivers NodeJS Python Go .NET Java // npm install --save neo4j-driver // node example.js const neo4j = require("neo4j-driver"); const driver = neo4j.driver("bolt://<HOST>:<BOLTPORT>", neo4j.auth.basic("<USERNAME>", "<PASSWORD>"), { /* encrypted: 'ENCRYPTION_OFF' */ }); const query = ` MATCH (p:Product)-[:PART_OF]->(:Category)-[:PARENT*0..]-> (:Category {categoryName:$category}) RETURN p.productName as product `; const params = { category: "Dairy Products" }; const session = driver.session({ database: "neo4j" }); session .run(query, params) .then((result) => { result.records.forEach((record) => { console.log(record.get("product")); }); session.close(); driver.close(); }) .catch((error) => { console.error(error); }); Helpful Tools for Modern App & Web Development Neo4j provides an array of tools, libraries, and frameworks to make development faster and easier. Developer tools like Neo4j Desktop, Browser, and Sandbox make it simple to learn and develop graph apps. The new Neo4j GraphQL Library translates GraphQL queries into Cypher, making it easier for GraphQL users to use Neo4j. It also streamlines integration of Neo4j with React, Vue, and other open source frameworks.
