This document provides an overview of Azure SQL Data Warehouse (SQL DWH), a cloud data warehouse service. It discusses SQL DWH's massively parallel processing (MPP) architecture that allows independent scaling of compute and storage. The document demonstrates how to create a SQL DWH, load data using PolyBase, and use common tools. It is intended to help users understand what SQL DWH is, how it works, and common scenarios it can be used for, such as processing large volumes of data without needing to purchase and manage hardware.
