The document discusses the convergence of SQL, NoSQL and Hadoop technologies. It notes that these were originally separated but are now joining together. Analytics problems now span these different platforms, and many platforms now support multiple data workloads and personas. However, challenges remain around common security, federated querying, and workload/query orchestration across platforms. The ideal solution would be a logical hub that can manage policies, security, and workloads across the different data platforms and engines.
