Microsoft’s Data Warehousing Strategies
Reducing complexityReducing 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
Addressing Scalability
Database that can scale upwards to up to 3TB
Scale downwards into the small and midsize business (SMB) market
Microsoft Data Warehousing Products
Two products that address the server and client
SQL Server 7.0 and Office 2000 (Excel 2000 in particular)
Data Warehousing Requirements
Access to diverse information sources Integrating and consolidating
information from heterogeneous data sources
Data warehouses
SQL Server 7.0 Features
Scalable Business Solutions Powerful Data Warehousing Integration with Microsoft Office 2000
Scalable Business Solutions
Terabyte-sized database support Scalability Easy to Build, Manage, and Deploy Designed for Mobile Computing An Ideal Platform for Commerce

Case Study: Shoney’s Restaurants
Performance Evaluation– Initial load of two to three years of historical
data– Nightly incremental updates that exceeded
120,000 rows per day– Modified several Microsoft Access-based sales
analysis applications– Analyze and report a variety of sales result
Microsoft Limitations
A complete range of knowledge-management systems requires other tools, notably ETT tools
Even the enhanced spreadsheet applications with Excel 2000 will still provide only rudimentary analysis
Microsoft Limitations
Scalability of SQL Server 7.0 not yet proven
These competitive claims were crystallized in "Oracle Million Dollar Challenge" Microsoft does not have a satisfactory answer to this
Microsoft’s Answer
Partnered with NCR to integrate its high-end Teradata server with SQL Server 7.0
