Reducing costs
Increasing scalability
Reducing Complexity
Released Two Technical Specifications
OLE DB for OLAP provides a common interface for front-end analysis tools to access OLAP engines
Open Information Model (OIM) - a metadata classification and organization standard
Reducing Costs
Bundled OLAP Services and supporting
technologies (DTS and an English Query front- end interface) free with SQL Server 7.0.
Cheaper than most standalone OLAP servers
