Tabular models leverage the use of Windows users and groups. Recall that in Chapter 5, Administration of Tabular Models, you added row-level security to a user to filter for one role to only see Ice conditions in the crash data. When the query is run, the security is checked to ensure that the user's role has the ability to retrieve the rows of data associated with the permission of the role, unlike multidimensional security, which uses cells and dimensions to determine what data can be accessed. In addition, tabular models do not have the ability to deny permissions such as does the multidimensional model. Tabular models rely on row-level security only. If a user is assigned to multiple roles, they obtain the rights from all the associated roles; for example, if the Read_Ice user is added to the Admin role, they would have all rights as an administrator as well. Pay close attention when setting up and deploying security. Tabular model security can be configured to use row filters...

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.
