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.

Building dimension hierarchies


Analysis Services hierarchies specify the navigation path for browsing dimension data. There are two types of hierarchies: attribute and user-defined hierarchies. For example, in the promotion dimension we just created, we immediately have a hierarchy for each attribute: Promotion Name, Start Date, End Date, English Promotion Category, English Promotion Type, Discount Percent, Minimum Quantity, and Maximum Quantity. Attribute hierarchies contain two levels.

The top-level is referred to as the All level and includes the aggregated value for all the members included in the attribute. For example, the English Promotion Category attribute hierarchy's All level will show the aggregate value of sales for all the promotion categories: Customer, No Discount, and Reseller. The other level in the same hierarchy will show individual promotion categories, such as Customer.

User hierarchies combine multiple attributes and must be defined explicitly. In this recipe we will...
