Web Pivot Control

Internet Support on Clients

Uses IIS to Provide Authentication Over the Internet

Uses HTTP to Pass Through Firewalls

Supports Automatic Setup through ASP

Requires SQL Server 2000 Enterprise Edition

Data Mining in Analysis Services

Data Mining Is The Process of Deducing Meaningful Patterns and Rules from Large Quantities of Data

Searches for Patterns in Data Rather than Answering Predefined Questions

Is Used To:

Provide historical insights

Predict future values or outcomes

Close the loop for analysis
