摘要： 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.

摘要： 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. Additional features include feasibility queries to determine if requested data exists in the key/value store before performing an expensive query; automatic query optimization using secondary indexes; and a usage history service to identify performance bottlenecks and fine tune the storage schema.

摘要翻译： 公开了提供对存储在非结构化键/值存储中的低级数据进行高级，基于本体的分析的系统和方法。 这些系统和方法允许分析师在不了解底层物理数据存储的情况下，了解来自不同来源的大量数据。 附加功能包括可行性查询，以确定在执行昂贵查询之前，密钥/值存储中是否存在请求的数据; 使用二次索引进行自动查询优化; 以及使用历史服务来识别性能瓶颈并微调存储模式。
