by Open Weaver kits ✔

Java Graph databases libraries are a relatively new database technology that has been gaining popularity in the last couple of years. They are especially useful for storing and querying relationships between entities. They have certain advantages over traditional relational databases, such as their ability to quickly traverse large graphs and answer complex queries with low latency. Neo4j is the most popular and mature option. It has all the basic features you need to get started, including support for multiple indexes, relationships and queries. It also offers a REST API that allows you to query your data from the browser or a client application. OrientDB is a newer alternative that offers an object-relational mapping (ORM) layer on top of its native graph database engine for easier integration with existing applications. This approach makes it easier to migrate from relational databases like MySQL or PostgreSQL into OrientDB, but it also means that some features may be missing from the graph database layer itself (for example, there's no support for transactions). Titan has a similar ORM layer as OrientDB but also supports advanced features such as transactional queries and automatic sharding across multiple nodes in a cluster. Some of the most widely used open source Java Graph databases libraries among developers include:
