Expert Cube Development with Microsoft SQL Server 2008 Analysis Services

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. This book is an invaluable guide for anyone who is planning to use Microsoft Analysis Services 2008 in a Business Intelligence project.

Designing simple dimensions


Next, let's build some dimensions. As this is one of the more complicated steps in the cube design process, it's a topic we'll return to again in future chapters when we need to deal with more advanced modeling scenarios. Right now we'll concentrate on the fundamentals of dimension design.

Using the 'New Dimension' wizard

Running the New Dimension wizard will give you the first draft of your dimension, something you'll then be able to tweak and tidy up in the Dimension Editor afterwards. The first question you'll be asked, on the Select Creation Method step, is how you want to create the new dimension and there are effectively two choices:

  • Create the dimension from an existing table or view in your data source (the Use an Existing Table option)

  • Have BIDS create a dimension automatically for you and optionally fill it with data (the other three options)

In keeping with our line of argument that all relational modeling work should be done outside BIDS, we recommend you...
