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

Configuring static row-level security


Static row-level security applies the filter to all members of the role. Roles can have filters on multiple tables. This recipe demonstrates this by adding a new filter on the Read_Ice role already created on the model.

Getting ready

Open the Crash_Data_Model in Visual Studio to bring up Model.bim. Then, change your view to the Diagram view to see the table relationships. In this recipe, you will review how row-level security is added and how it works. You will add a filter on the LIGHT_T table and then add a filter on the CRASH_DATA_T table.

In SQL Server Management Studio, the current security is only limiting rows to Ice conditions.

How to do it...

  1. Select the Model menu and then Roles to bring up the Role Manager window.

  2. Select Read_Ice to see the row filter already applied.

  3. In the DAX Filter area for the LIGHT_T table enter:

            =LIGHT[LIGHT_CONDITION]="Dawn" 
    

  4. Deploy the model and review the results in SQL Server Management Studio.
