Neo4j in 100 Seconds

Neo4j is a graph database created in 2007 by Emil Ifram, written in Java, and known for its property graph model. Unlike traditional relational databases, Neo4j uses nodes, edges, and properties to represent data, making it intuitive for modeling complex relationships. It is used in applications like recommendation engines and social media platforms. Neo4j can be self-hosted or used via Aura, a cloud-based service. Data is managed using Cypher, a declarative query language. Neo4j supports advanced querying, allowing for pattern matching and data analysis, making it a powerful tool for developers.
