When your application depends on connections among data points, a graph database can make those relationships queryable. Compare query languages and graph algorithms alongside ACID transactions and vector search to see which capabilities fit your workload. Deployment and included storage also shape the technical picture, while free-plan availability and paid-from pricing help frame costs. ArcadeDB, LadybugDB and TigerGraph are among the options to consider. The listed criteria span both database behavior and operational choices, so weigh them against how you plan to query, host and scale connected data.
