oracle Data Mining

 Executive Overview
The Oracle Data Mining Option provides powerful data mining functionality within the Oracle Database. It enables you to discover new insights hidden in your data and to leverage your investment in Oracle Database technology. With Oracle Data Mining, you can build and apply predictive models that help you target your best customers, develop detailed customer profiles, and find and prevent fraud. Oracle Data Mining helps your company better compete on analytics.
In-Database Data Mining
With Oracle Data Mining, everything occurs in the Oracle Database—in a single, secure, scalable platform for advanced business intelligence. Oracle Data Mining represents a breakthrough in business intelligence. In contrast to traditional statistical software that requires data extraction to separate servers, which may be insecure and costly to maintain, Oracle Data Mining embeds a wide-range of mining functions inside the database—where the data is stored. Coupled with the power of SQL, Oracle Data Mining eliminates data movement and duplication, maintains security and minimizes latency time from raw data to valuable information.
Oracle Data Mining enables you to:
• Leverage your data to discover patterns and valuable new insights
• Build and apply predictive models and embed them into dashboards and applications
• Save money. Oracle Data Mining costs significantly less than traditional statistical software. As an integrated component of your Oracle IT platform, Oracle Data Mining significantly reduces your total cost of ownership.
