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.

Adding KPIs to our cube

KPIs are used by businesses to evaluate performance over time. KPIs in multidimensional models in SSAS are server-based and can be used by various end user tools such as Excel. The advantage here is that a business KPI can be created and shared easily within an organization.

Understanding the basics of a KPI

A typical KPI is built on the following components:

  • Goal or target
  • Value or actual
  • Status of the value compared to the goal
  • Trend of the value to meeting the goal

These values can use indicators that typically work from a -1 to 1 value system. Here, -1 is measured as not meeting the goal, and 1 as meeting the goal. All these values are built with MDX, which is what we will dig into now.

Building your KPI

First, you need to open the KPI tab in the Cube Design window in your Visual Studio project. Once you have that open, create a new KPI by right-clicking in the KPI Organizer pane or selecting the New KPI option from...
