ETL with Azure Cookbook

By: Christian Cote, Matija Lah, Madina Saitakhmetova

Overview of this book

ETL is one of the most common and tedious procedures for moving and processing data from one database to another. With the help of this book, you will be able to speed up the process by designing effective ETL solutions using the Azure services available for handling and transforming any data to suit your requirements. With this cookbook, you’ll become well versed in all the features of SQL Server Integration Services (SSIS) to perform data migration and ETL tasks that integrate with Azure. You’ll learn how to transform data in Azure and understand how legacy systems perform ETL on-premises using SSIS. Later chapters will get you up to speed with connecting and retrieving data from SQL Server 2019 Big Data Clusters, and even show you how to extend and customize the SSIS toolbox using custom-developed tasks and transforms. This ETL book also contains practical recipes for moving and transforming data with Azure services, such as Data Factory and Azure Databricks, and lets you explore various options for migrating SSIS packages to Azure. Toward the end, you’ll find out how to profile data in the cloud and automate service creation with Business Intelligence Markup Language (BIML). By the end of this book, you’ll have developed the skills you need to create and automate ETL solutions on-premises as well as in Azure.

Loading multiple files using Data Factory

We are going to use BIMLStudio 2019 to build a more elaborate solution. Let's say we want to load a set of files available online into our on-premises SQL Server database. We want to use the data from these files to do reports by joining them with on-premises data. In this recipe, we will look at creating a Data Factory solution that loads a set of data files in parallel from the website FiveThirtyEight.com into Azure Data Lake Storage Gen2, and then into an on-premises SQL Server database. FiveThirtyEight.com is a data journalism organization that provides opinions and analysis on politics, economics, and sport, based on data science and analytics. The site provides access to a collection of datasets easily available for download. For our recipe, we will be downloading a set of CSV files containing statistical weather data, such as actual temperature, maximum temperature, minimum temperature, and levels of precipitation for every city...
