The Multi-Dimensional Analysis Server (MDAS) registers itself with the Central Management Server ( CMS ) (CMS), and its services are available for consumption by other servers or client applications that communicate via the BusinessObjects Enterprise framework.
The MDAS provides BusinessObjects Enterprise client applications with an extensible and efficient framework for accessing multi-dimensional (OLAP) data. It provides access to multi-dimensional data and also converts the raw data into XML packages, which the requesting client application renders into a specific presentation format: Excel spreadsheet, PDF, or Voyager crosstabs and charts.
OLAP single sign-on (SSO) is only supported for Microsoft Analysis Services and SAP BW.
