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.

Using Convert SSIS package to Biml

The sample DailyETLMain.dtsx SSIS package for the WideWorldImporters solution first has three tasks that precede a list of Sequence Containers, and they are quite basic. So, instead of going over the Biml to create them, which we have already covered in previous recipes, let's demonstrate one helpful functionality in BimlExpress that can be a great learning tool as well – it is the option to Convert SSIS Package to Biml.

What we want to accomplish in this recipe is to do the opposite of what we were doing in previous recipes and to generate Biml code from an existing SSIS package.

Getting ready

Open Visual Studio 2019, and then open the ETLInAzure SSIS project.

How to do it…

Add a new Biml file to your solution and rename it to Recipe5.biml. Copy the code from Recipe4.biml to the new Biml file because it will be our starting point:

  1. Change the name of the package in the Package element to Recipe5.
  2. Right...
