Apache TinkerPop™ is a graph computing framework for both graph databases (OLTP) and graph analytic systems (OLAP).

Apache TinkerPop™ is a graph computing framework for both graph databases (OLTP) and graph analytic systems (OLAP). Graph systems that are TinkerPop-enabled, allow users to the ability to utilize the various aspects of the TinkerPop stack in development of vendor-agnostic graph applications. The key component to the TinkerPop stack is the Gremlin, a graph traversal language, which allows users to query and manage a graph.
