If you know what a graph database is and the qualities of the best databases, selecting one for your needs becomes much easier. Hence, first, let us discuss the same.

What Are Graph Databases

Graph Databases are databases to store and represent data using graph structures with edges, nodes, and properties.

Going deeper into the details, vertices or entities in the graph are nodes. Whereas, relationships or lines that connect the nodes are edges. And the attributes on edges or nodes are known as properties.

Used in search engines like the Knowledge Graph of Google, these databases provide users with more flexibility than a relational database, making them a better choice for managing interconnected information.

While choosing the best graph databases for your requirements, you should look for the following qualities or features.
