Overview of this book

Microsoft's SQL Server Analysis Services 2008 is an OLAP server that allows users to analyze business data quickly and easily. However, designing cubes in Analysis Services can be a complex task: it's all too easy to make mistakes early on in development that lead to serious problems when the cube is in production. Learning the best practices for cube design before you start your project will help you avoid these problems and ensure that your project is a success. This book offers practical advice on how to go about designing and building fast, scalable, and maintainable cubes that will meet your users' requirements and help make your Business Intelligence project a success. This book gives readers insight into the best practices for designing and building Microsoft Analysis Services 2008 cubes. It also provides details about server architecture, performance tuning, security, and administration of an Analysis Services solution. In this book, you will learn how to design and implement Analysis Services cubes. Starting from designing a data mart for Analysis Services, through the creation of dimensions and measure groups, to putting the cube into production, we'll explore the whole of the development lifecycle.

Chapter 7. Adding Currency Conversion

In this chapter we will discuss how we can implement currency conversion in an Analysis Services solution. As we will see, it is not always a good idea to perform this currency conversion in the cube itself, it could be better to implement it in the ETL phase—it all depends on our requirements and analysis needs. We will provide some examples of different choices that are available in different circumstances.

BI Development Studio provides a wizard to implement currency conversion in the cube, automatically generating the necessary objects and MDX scripts. We will describe how to use this wizard in the most effective way. Then, we will see how to implement currency conversion using the MeasureExpression property of a measure, a feature that is faster but that is also only available in the Enterprise Edition of Analysis Services.
