AgensGraph is a multi-model (Relational + Graph) database management system. It stores, analyzes, and visualizes various data as graphs. AgenGraph handles connected data and provides features including ACID transactions, multi-version concurrency control, stored procedure, and a flexible data model(JSON).
On the basis of PostgreSQL RDBMS, AgensGraph can retreive a result from both relational and graph by a single query at the same time. The relational data can be easily migrated into AgensGraph. The utilization of the graph database provides the user with a broader basis for advanced data analysis, powered by AgensGraph’s web interface (Agensbrowser) for data visualization and hybrid query (SQL & Cypher) support.
