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 an SSIS package containing a Data Flow Task

Here, we are finally getting to a more complicated SSIS package that will contain a Data Flow Task, and in a previous recipe, Generating a mass change to stored procedures, we already made some preparation changes to stored procedures in the sample WideWorldImporters database to overcome the limitations of the Biml related to the use of temporary tables. Now we can concentrate on the Data Flow Task itself.

Getting ready

This is our last recipe for SSIS packages, and it is the most complex one, so let's buckle up and get ready for a bumpy ride! Open Visual Studio 2019, and then open the ETLInAzure SSIS project.

How to do it…

Let's add a new Biml file to start our recipe:

  1. Add a new Biml file to your solution. Rename it to Recipe7.biml. Copy all the code from Recipe5.biml into Recipe7.biml, because in this recipe we are going to continue to build upon what was done in the Generating an SSIS package...
