33 Data Mining Focus Complete set of analytics Embedded data mining
Most popular data mining algorithms (5 new) Enhanced creating, editing, and viewing environment Embedded data mining Embed data mining in LOB applications Complete SQL language based API Native XML/A support Integrated solution Tight integration with Relational, OLAP, DTS, Reporting technologies Comprehensive SQL Server BI platform Alliance with ISVs Focus on broadening the market Agreed on finalizing DM industry standard based on OLE DB for DM and XML/A Microsoft's goal for the data mining functionality in SQL Server 2005 is to build tools that: Are easy to use Provide a complete set of features Are easily embedded in production applications Integrate closely with the other SQL Server BI technologies, and Extend the market for data mining applications. To date, the development of such applications has been focused on the biggest problems at the biggest companies – those who can afford scarce analytical talent and high development costs that have traditionally been required to build a data mining application. Just as Microsoft's OLAP technologies have helped the OLAP market to grow, we are looking to extend data mining technologies to enterprises and corporate departments that have not been able to develop such applications in the past. Use the SQL Server 2005 Data Mining tools to explore a set of data for patterns, and then optionally perform prediction on those patterns. That's all data mining is: exploration, pattern discovery, and pattern prediction.

34 Complete Set of Algorithms
Decision Trees Clustering Time Series Introduced in SQL Server 2000 Sequence Clustering Association Naïve Bayes All data mining tools, including Microsoft SQL Server 2005 Analysis Services, use multiple algorithms. Analysis Services, of course, is extensible; third party ISVs can develop algorithms that snap in seamlessly to the Analysis Services data mining framework. Depending on the data and the goals, different algorithms are preferred, and each algorithm can be used for multiple problems. Analytical problem Examples Microsoft algorithms Classification: Assign cases to predefined Decision Trees Naďve Bayes Nueral Nets classes such as "Good" vs "Bad“ Credit risk analysis Churn analysis Customer retention Neural Net

35 SQL Server The Comprehensive, Integrated Data Platform
Talking points: SQL Server is a comprehensive, integrated end to end data platform including: Core database engine: secure, reliable, highly available data store Data transformation and replication services (DTS, Replication) facilitate enterprise wide data integration, data warehouse creation, data replication for distributed or mobile data processing applications, and systems availability Deriving additional value from your data: Notification Services, Data Analysis, Data Mining, Reporting Management tools – SQL specific management suite as well as tight integration with tools such as MOM, SMS Development tools – BI specific development toolset as well as tight integration with Visual Studio Flexible, extensible: Every major subsystem in SQL Server ships with it’s own Object Model and set of APIs to you to extend the data system in any direction that is unique to your business Interoperable: Standard data access protocols drastically reduce the time it takes to integrate data in SQL Server with existing systems. In addition, native web service support is built into SQL Server to ensure interoperability with other applications and platforms SQL Server is the only database to include all of this functionality out of the box. Competitive offerings rely on third part applications to address key functionality and/or charge for incremental functionality (such as BI) Also provide entry level SKUs for lightweight data needs (Express, Workgroup) Scales to your needs: support for databases from the mobile device to the datacenter SQL Server Mobile, 32 bit, 64 bit Hardware platform range of SQL Server includes: Single Pocket PC CPU systems, Throughout mobile and desktop class PCs, Through Multi-CPU server systems All the way up to 64-processor Enterprise Data Center systems
