Vertica

Vertica gives a top-tier, unified analytics platform that will always be free of the hidden framework. Connecting DronaHQ to Vertica lets you construct UIs rapidly on top of your Vertica information. For instance, you could fabricate an instrument to adjust metadata tables. You can peruse information from Vertica and afterward compose information back to it either straightforwardly, or through a different API.
