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.

Creating data sources


Once we've created a new project and configured it appropriately, the next step is to create a data source object. Even though you can create multiple data sources in a project, you probably shouldn't. If you've read the previous chapter, then you'll know that we recommend that all of the data needed for your cube should already be present in a single data mart.

You are then faced with the choice of which OLE DB provider to use, since there are often several different options for any given relational database. For SQL Server data sources, you have the option of using the SQLClient .NET data provider, the Microsoft OLE DB provider for SQL Server and the SQL Server Native Client (often referred to as SNAC). You should always choose the SQL Server Native Client since it offers the best performance. For Oracle data sources, the choice is more complicated since, even though Oracle is a supported data source for Analysis Services, there is a long list of bugs and issues....
