A graph database is an online database management system with Create, Read, Update and Delete (CRUD) operations working on a graph data model. A graph database is built to handle highly connected data and ensures future scalability. Its richly and variably structured data model supports both hierarchical and non-hierarchical structures and capture rich metadata regarding every element in the database.
Graph database technology significantly improves analytics on complex data relationships, enables rapid storage and retrieval of information, and facilitates real-time reporting.
World-wide tech organizations such as Google, LinkedIn and Facebook have all deployed graph databases throughout their growing infrastructure.
