Federated queries

Unlike traditional database systems, Presto doesn’t have its own native database storage. Instead, Presto supports separation of compute and storage, with dozens of databases, NoSQL databases, data warehouses, data lakes, data lakehouses, and more.

With Presto’s federated query capability (frequently referred to as data federation, or simply federation), you can combine data from Data Gate on Cloud, Db2® for z/OS®, and other sources.
