Systems and methods are disclosed that provide high-level, ontology-based analysis of low-level data stored within an unstructured key/value store. The systems and methods allow an analyst to make sense of massive amounts of data from diverse sources without having any knowledge of the underlying physical data storage. The systems and methods provide flexible ontology assisted addressing, embedding such addressing in existing query languages such as widely used Structured Query Language (SQL), and returning results and provenance information of the results.
