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 dynamic filter security


Dynamic security uses additional information to filter the data to allow more flexibility than row-level security. In this recipe, you will create a security table that has two users, Bob and John. Then, by implementing dynamic security, the data that each is able to see will be shown.

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 create a new security table and then implement dynamic security for these users by using the USERNAME() function. The USERNAME() function will return the DOMAIN\User from the account accessing the model.

How to do it...

  1. Select the Model menu and the Existing Connections...:

  2. Then select Open to bring up the existing connection information:

  3. The default import wizard is set to Select from a list of tables and views to choose the data to import. Click on Next:
