Overview of this book

SQL Server Integration Services is a tool that facilitates data extraction, consolidation, and loading options (ETL), SQL Server coding enhancements, data warehousing, and customizations. With the help of the recipes in this book, you’ll gain complete hands-on experience of SSIS 2017 as well as the 2016 new features, design and development improvements including SCD, Tuning, and Customizations. At the start, you’ll learn to install and set up SSIS as well other SQL Server resources to make optimal use of this Business Intelligence tools. We’ll begin by taking you through the new features in SSIS 2016/2017 and implementing the necessary features to get a modern scalable ETL solution that fits the modern data warehouse. Through the course of chapters, you will learn how to design and build SSIS data warehouses packages using SQL Server Data Tools. Additionally, you’ll learn to develop SSIS packages designed to maintain a data warehouse using the Data Flow and other control flow tasks. You’ll also be demonstrated many recipes on cleansing data and how to get the end result after applying different transformations. Some real-world scenarios that you might face are also covered and how to handle various issues that you might face when designing your packages. At the end of this book, you’ll get to know all the key concepts to perform data integration and transformation. You’ll have explored on-premises Big Data integration processes to create a classic data warehouse, and will know how to extend the toolbox with custom tasks and transforms.

Preface

Testing the randomness of the split with a SSAS decision trees model


You need to test the randomness of the split from the previous recipe. You will use the SSAS decision trees algorithm to check whether you can predict a set membership with input variables. You should get a very shallow tree, meaning there are no patterns that could explain the set membership.

Getting ready

For this recipe, you need to have SSAS installed in multidimensional and data mining mode. You also need to finish the previous recipe.

How to do it...

  1. In SSDT, add a new analysis services multidimensional and data mining project to the Chapter08 solution and name the project Ch08SSAS.
  2. In solution explorer, right-click the Data Sources folder and select New Data Source to create a new data source.
  3. In the Data Source Wizard welcome screen, click Next.
  4. In the Select how to define the connection screen, create a data source using a connection AdventureWorksDW2014 database. Click Next.
  5. In the Impersonation Information screen, you...
