Hands-On SQL Server 2019 Analysis Services

By: Steve Hughes

Overview of this book

SQL Server Analysis Services (SSAS) continues to be a leading enterprise-scale toolset, enabling customers to deliver data and analytics across large datasets with great performance. This book will help you understand MS SQL Server 2019’s new features and improvements, especially when it comes to SSAS. First, you’ll cover a quick overview of SQL Server 2019, learn how to choose the right analytical model to use, and understand their key differences. You’ll then explore how to create a multi-dimensional model with SSAS and expand on that model with MDX. Next, you’ll create and deploy a tabular model using Microsoft Visual Studio and Management Studio. You'll learn when and how to use both tabular and multi-dimensional model types, how to deploy and configure your servers to support them, and design principles that are relevant to each model. The book comes packed with tips and tricks to build measures, optimize your design, and interact with models using Excel and Power BI. All this will help you visualize data to gain useful insights and make better decisions. Finally, you’ll discover practices and tools for securing and maintaining your models once they are deployed. By the end of this MS SQL Server book, you’ll be able to choose the right model and build and deploy it to support the analytical needs of your business.

Creating KPIs

KPIs are used by businesses to evaluate performance over time. Businesses use KPIs in dashboards to show progress toward specific goals or targets. KPIs use a combination of symbols and numbers to represent current states and trends. KPIs in tabular models in SSAS are server-based and can be used by various end user tools such as Excel and Power BI. The advantage here is that a business KPI can be created and shared easily within an organization. This allows multiple users to include KPIs in their reporting with ease and consistency.

Understanding the components in a tabular model KPI

In tabular models, KPIs are more simplistic than the KPIs in multidimensional models. They are also much easier to create. KPIs are created directly from the measures. When creating a KPI, you need to understand the five components that make up the KPI:

  • Base value: The base value is the measure you select when creating the KPI. It is what you are measuring against the target...
