Neo4j is a graph database that stores data in a logical and intuitive manner, prioritizing representations, discoverability, and maintainability of data relationships. It meets the top three goals developers look for when evaluating databases: intuitiveness, speed, and agility. With Neo4j, businesses can make better and faster decisions, perform complex business logic, and adapt to changes quickly, thanks to its declarative query language Cypher and real-time processing capabilities. The database is being used by major companies such as eBay, Telenor, Cisco, adidas, and Walmart, and has led to a surge in demand for professionals with Neo4j skills, prompting Edureka to launch an online course that covers the technology in detail.
