SQL Server Analysis Services 2012 Cube Development Cookbook

SQL Server Analysis Services 2012 Cube Development Cookbook

Overview of this book

Microsoft SQL Server is a relational database management system. As a database, it is a software product whose primary function is to store and retrieve data as requested by other software applications. SQL Server Analysis Services adds OLAP and data mining capabilities for SQL Server databases. OLAP (online analytical processing) is a technique for analyzing business data for effective business intelligence. This practical guide teaches you how to build business intelligence solutions using Microsoft’s core product – SQL Server Analysis Services. The book covers the traditional multi-dimensional model which has been around for over a decade as well as the tabular model introduced with SQL Server 2012. Starting with comparing MultiDimensional and tabular models – discussing the values and limitations of each, you will then cover the essential techniques for building dimensions and cubes. Following on from this, you will be introduced to more advanced topics, such as designing partitions and aggregations, implementing security, and synchronizing databases for solutions serving many users. The book also covers administrative material, such as database backups, server configuration options, and monitoring and tuning performance. We also provide a primer on MultiDimensional eXpressions (MDX) as well as Data Analysis expressions (DAX) languages. This book provides you with data cube development techniques, and also the ongoing monitoring and tuning for Analysis Services.

Sorting the attributes

By default, each dimension attribute is sorted according to its key column values, but this may or may not fit your requirements. Additional options include sorting the attribute by its name or by another attribute's name or key. For example, ordering a month attribute within the date dimension based on an attribute name will clearly not work; this is because we would see February prior to January since the letter "F" precedes "J" in alphabetical order. More than likely we want to see data sorted based on the occurrence of months in a calendar, rather than alphabetically. We can manage the sorting of an attribute using the OrderBy and OrderByAttribute properties. In this recipe we will sort the English Promotion Type attribute based on English Promotion Category.

How to do it...

Let's get started with sorting the attributes:

Click on the English Promotion Type attribute on the Dimension Structure tab to list the properties of this attribute.
Within the Properties window...
