Data virtualization software gives you ways to access and query data across sources. The ranking orders the options, while the listed criteria let you compare source connectors and access protocols with REST API access and semantic-layer support. Query acceleration and deployment model offer further distinctions to consider alongside your intended use. Check free-plan availability and paid-from pricing for cost context. Enterprise Enabler, Query Streams, and Stardog appear among the first entries, followed by Virtuoso Universal Server and Apache Drill.
