Definition of PolyBase

A Microsoft technology available within the Microsoft Analytics Platform System to query Hadoop data that is stored in Hadoop clusters or in an Azure Blob Storage by using Transact-SQL (T-SQL) or to query semi-structured data and join the results with relational data sets stored in SQL Server, eliminating the need to extract, transform, and load data into the relational data warehouse and the requirement of additional manual processes, skills, or training in Hadoop.
