Tabular Modeling with SQL Server 2016 Analysis Services Cookbook

By: Derek Wilson

Overview of this book

SQL Server Analysis Service (SSAS) has been widely used across multiple businesses to build smart online analytical reporting solutions. It includes two different types of modeling for analysis services: Tabular and Multi Dimensional. This book covers Tabular modeling, which uses tables and relationships with a fast in-memory engine to provide state of the art compression algorithms and query performance. The book begins by quickly taking you through the concepts required to model tabular data and set up the necessary tools and services. As you learn to create tabular models using tools such as Excel and Power View, you’ll be shown various strategies to deploy your model on the server and choose a query mode (In-memory or DirectQuery) that best suits your reporting needs. You’ll also learn how to implement key and newly introduced DAX functions to create calculated columns and measures for your model data. Last but not least, you’ll be shown techniques that will help you administer and secure your BI implementation along with some widely used tips and tricks to optimize your reporting solution. By the end of this book, you’ll have gained hands-on experience with the powerful new features that have been added to Tabular models in SSAS 2016 and you’ll be able to improve user satisfaction with faster reports and analytical queries.

Preface

Importing sample datasets


For the examples in this chapter you will import two sets of data to create tables inside the model. This first table is a list of all states in the United States plus the District of Columbia. The second data set is a short list of famous landmarks.

Note

These examples are available at https://github.com/derekewilson/SSAS_2016_Tabular_Model.

Getting ready

This example assumes you have a working tabular mode server and SQL Server Data Tools installed.

How to do it...

  1. Open Visual Studio, select File and then New Project.

  2. On the next screen select Analysis Services Tabular Project to create a new Analysis Service tabular project.

  3. Select Model from the menu and Import from Data Source.

  4. Select Excel File from the bottom of the Table Import Wizard and click Next.

  5. Browse to the location of the US States.xlsx file. Check the Use first row as column headers box.

  6. Select the Service Account to specify a user that has access to the data source. Click Next.

  7. Review the Source Table information and click Finish.

  8. Click Close after successfully importing the data.

  9. Now repeat steps 4-8 and import into the data the Famous Landmarks.csv file.

How it works...

Let's review what was done in the previous steps for this first recipe. In steps 1 and 2 we created a new Tabular Model project and selected the option to import data. Then in steps 3 and 4 we selected the source data type of Excel and chose the file to import that included a list of the States in the USA. During step 5 we selected how the data source can be accessed via user security. In step 6, we reviewed the import process and started loading the data. In step 7 we were able to see that the data was successfully imported. Then you repeated the process to import the Famous Landmarks file. You now have two data tables loaded into your model that Tabular mode can use.
