Apache AGE is a PostgreSQL Extension that provides graph database functionality. AGE is an acronym for A Graph Extension, and is inspired by Bitnine's fork of PostgreSQL 10, AgensGraph, which is a multi-model database. The goal of the project is to create single storage that can handle both relational and graph model data so that users can use standard ANSI SQL along with openCypher, the Graph query language.
Here is the link to the latest Apache AGE documentation. You can learn about how to install Apache AGE, its features and built-in functions and how to use various Cypher queries.
