Microsoft’s Data Warehousing
Strategies
Reducing complexity
 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 frontend 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

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 knowledgemanagement 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
