Microsoft’s Data Warehousing Strategies
Reducing complexityReducing costs Increasing scalability
![Page 3: M icrosoft Data Warehousing - SQL Server 7.0 - State of the Technology Presentation by Sujata Angara Nakul Johri Sang Ho Park](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2c5503460f94b1b9d8/html5/thumbnails/3.jpg)
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
![Page 4: M icrosoft Data Warehousing - SQL Server 7.0 - State of the Technology Presentation by Sujata Angara Nakul Johri Sang Ho Park](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2c5503460f94b1b9d8/html5/thumbnails/4.jpg)
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
![Page 5: M icrosoft Data Warehousing - SQL Server 7.0 - State of the Technology Presentation by Sujata Angara Nakul Johri Sang Ho Park](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2c5503460f94b1b9d8/html5/thumbnails/5.jpg)
Addressing Scalability
Database that can scale upwards to up to 3TB
Scale downwards into the small and midsize business (SMB) market

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
![Page 22: M icrosoft Data Warehousing - SQL Server 7.0 - State of the Technology Presentation by Sujata Angara Nakul Johri Sang Ho Park](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2c5503460f94b1b9d8/html5/thumbnails/22.jpg)
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
![Page 23: M icrosoft Data Warehousing - SQL Server 7.0 - State of the Technology Presentation by Sujata Angara Nakul Johri Sang Ho Park](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2c5503460f94b1b9d8/html5/thumbnails/23.jpg)
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
![Page 24: M icrosoft Data Warehousing - SQL Server 7.0 - State of the Technology Presentation by Sujata Angara Nakul Johri Sang Ho Park](https://reader030.vdocuments.site/reader030/viewer/2022032803/56649e2c5503460f94b1b9d8/html5/thumbnails/24.jpg)
Microsoft’s Answer
Partnered with NCR to integrate its high-end Teradata server with SQL Server 7.0
