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.

Accessing Analysis Services from outside a domain


So far we've seen that, in order to let a user access a cube, that user needs to be a user on the same domain as Analysis Services. We have seen that roles are based on Windows users and groups, and that Analysis Services does not implement any other forms of authentication.

Nevertheless, it is possible to let users outside a domain access Analysis Services if we set up HTTP access via Internet Information Server (IIS). This method uses a DLL called MSMDPUMP.DLL that acts as a bridge between IIS and Analysis Services; when called, this DLL connects to Analysis Services and impersonates a Windows user, which can be a domain user or a local user on the server hosting Analysis Services and IIS. The DLL is placed in a virtual directory in IIS; the client application then connects to the DLL via IIS and IIS therefore handles the authentication. Using integrated Windows authentication is the recommended option, but it is also possible to use other...
