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.

Modifying model columns


In this recipe, we will modify the properties of the columns on the WEATHER table. Modifications to the columns in a table make the information easier for your users to understand in the reporting tools. Some properties determine how the SSAS engine uses the fields when creating the model on the server.

How to do it...

  1. In Model.bim, make sure you are in the Grid view and change to the WEATHER_T tab.

  2. Select WEATHER Column to view the available Properties and make the following changes:

    • Select the Hidden property to True

    • Select the Unique property to True

    • In the Sort By Column select WEATHER_CONDITION

    • Select Summarize By to Count

  3. Next, select the WEATHER_CONDITION column and modify the following properties:

    • In the Description add Weather at time of crash

    • Set the Default Label property to True

How it works...

This recipe modified the properties of the measure to make it better for your report users to access the data. The WEATHER code column was hidden so it will not...
