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

Case Study: Shoney’s Restaurants

Background Platforms Issue Description Product Functionality Strengths Weaknesses Technical Support

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
