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.

Exploring more MDX expressions

Entire books have been written on MDX exclusively. MDX is a very powerful query and expression language. We have touched just a small part of what is possible. This section will present a few additional expressions and techniques for you to practice with. We will primarily be working in SSMS to illustrate both member creation and various query techniques. Any member created in SSMS can be moved to the cube, as we have demonstrated throughout this chapter.

Traversing hierarchies

Earlier in the chapter, we talked about how traversing the cube is like working with a family tree. Functions such as parent, children, ancestor, descendant, and even cousin exist in MDX. Here are some examples for you to use with our cube.

members

members returns all the members of a level or hierarchy depending on the context. We have used members in several queries already. Let's look at the City dimension for an easy example of using members. We can use members...
