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.

Generating a basic SSIS package

Now we are ready to get to SSIS packages. Let's start with an SSIS package that is similar to a master package, because that type of package is best suited to automation. Master packages are usually simple and call other packages in a linear manner. We will use a Wide World Importers sample SSIS project for this recipe. In the Wide World Importers sample project, DailyETLMain.dtsx is a single package, and it contains a set of Sequences for each destination table. Each sequence has more logic in it. All we want to do in this recipe is to generate an SSIS package with a collection of empty Sequence Containers for each destination table.

Getting ready

There are a couple of steps we need to take before beginning:

  1. Open Visual Studio 2019 and then open the ETLInAzure SSIS project. First, we will need to prepare our driving force: metadata. You will need to create a new SQL Server database, BIMLMetadata, where the metadata and configuration...
