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.

Summary


In this chapter we have learned that:

  • The only form of authentication supported by Analysis Services is Windows authentication. If access need to be granted from outside the domain the Analysis Services server belongs to, then it is possible to configure HTTP access to Analysis Services via IIS.

  • Analysis Services security is based on roles. Only Windows users and groups can be members of roles.

  • If a user belongs to multiple roles, they will have all of the permissions granted to them by every role they are a member of; there is no concept of "deny wins over grant".

  • We can use cell security to secure individual cell values within the cube. Cell security can cause poor query performance and should only be used if there is no other option.

  • Dimension security lets us allow or deny access to members on a hierarchy. Using the Enable Visual Totals option then controls whether values at higher granularities are calculated based on all of the members on the hierarchy or just the members that the...
