Query Any Data by Wayne Eckerson

This document discusses strategies for querying different types of data. It notes that while relational databases can query transactional and structured data using SQL, they are missing 80% of unstructured and multi-structured data. Non-relational databases can query all types of data but are not SQL-based. The document outlines SQL and NoSQL strategies for querying data, including using SQL on Hadoop, SQL-like languages, search APIs, blobs and text mining, and NoSQL APIs. It also mentions querying data both on-premises and in the cloud through query virtualization and search.
