Neo4j is a high-performance graph database, which gives the flexibility to access it from various languages and in different options. The two most popular ones being the embedded option and the server mode. The embedded mode gives the user the power to embed it within the application to get high performance with low latency, whereas the server mode gives the user the flexibility to access the services using the REST endpoint, making it (virtually) language-neutral. Let's briefly discuss both the modes:
