What is Web Services for DB2 Intelligent Miner?
Web Services for DB2 Intelligent MinerTM is a collection of Web services that allow clients to describe and perform basic data-mining tasks using XML, XML Schema, and XPath on top of DB2 Intelligent Miner. It provides simple access to the main functions of DB2 Intelligent Miner Modeling and Scoring without requiring a single line of SQL to be written. In data-mining terms, modeling is the step of developing analytical models based on a set of input data. Scoring allows one to apply these models on large databases or single records to predict values. The Web services allow a client to execute these operations as tasks defined in XML. Modeling and scoring can thereby be executed as synchronous or asynchronous calls. Furthermore, the services interchange models by using the Predictive Model Mark-up Language (PMML), which is an open standard for describing data-mining models in XML.
How does it work? This technology is also based on other open standards: XPath as a query language and XML for defining tasks, input data, and results. It does not require the knowledge of complex data-mining APIs (as in XML for Analysis). XPath was designed to address parts of an XML document and can be used to navigate through the hierarchical structure of any XML document. This technology uses XPath to query parts from a service's metadata and to query data from tables in a DB2 database. XML Schema allows definition of the structure and content of an XML document. It is used by this technology to define the structure of the different data-mining operations.
The Web services provided by this technology enable DB2 Intelligent Miner to be used in the service-oriented world. It helps integrate data mining into various solutions by providing a simple and Web-based interface. Additionally, it eases the deployment of data-mining applications in distributed environments.

| | About the technology author(s):
This technology was developed by Stefan Eberl as part of his master's thesis. Mr. Eberl graduated in 2004 from the Fachhochschule Furtwangen in Germany. During his study, he worked in several IBM projects conducted by IGS, Human Resources, and finally the development lab in Boeblingen. Mr. Eberl can be reached here.
The technology is now developed and maintained by members of the DB2 Intelligent Miner development team in the IBM development laboratory, Boeblingen, Germany. Any questions will be answered in the discussion forum.
