FeaturesSubject: Data Mining Software that can do analysis over multiple tables Most of the time data mining is done over a single flat table. However, in some situations we need to do data mining over multiple tables, perhaps because the data is too large, or remote, or distributed, or for other reasons. In previous KDnuggets News I asked "...which data mining software can do analysis over multiple tables." SQL server has some of that capability. David Jensen writes: One candidate would be Proximity, an open-source environment for knowledge discovery in relational data produced by my research group. Details can be found at: http://kdl.cs.umass.edu/proximity/index.html Proximity runs under Linux, MacOS, and Windows.

Dusan Toman writes The upcoming Miner3D Release 7.1 (June 2008) comes with extensive support for both Oracle OLAP and SQL Server Analysis Services and empowers users with intuitive analysis of multiple OLAP cubes at once.
Arno Knobbe writes Safarii is a state-of-the-art Data Mining environment for analysing large relational databases. It is unique in its wide support for a new data analysis paradigm, called Multi-Relational Data Mining (MRDM). This makes it an ideal tool for knowledge discovery in a wide range of industries, such as retail, enterprise resource planning, banking, e-commerce, bio-informatics and molecular modelling. As most Data Mining tools, Safarii mines a given database for subgroups with interesting or surprising characteristics (customers with a high response rate to a mailing, website visitors with above-average spending, a class of chemical compounds with increased carcinogenic potential). Whereas traditional tools only deal with a single table and the flat features stored in there (age, balance, etc.), Safarii is able to involve structural information stored in several tables. This enables Safarii not only to deal with objects that are inherently structural (molecules, weblogs, etc.) and hard to process by traditional tools, but also to integrate data originating from multiple sources such as different business applications, as well as information from previous analyses and domain knowledge. Safarii supports a range of techniques for exploratory data analysis, building predictive models, and deploying the results in an operational environment. More information concerning Safarii can be found at www.kiminkii.com/safarii.html.
