Enterprise Miner is a data mining package with integrated linkage to
the popular commercial SAS statistical application. It provides a
range of techniques accessed through a graphical user interface, using
the node (representing data processing and modelling steps) and link
paradigm to build process flows. The product is priced at the higher
end of the market with a license restricting its usage to the owner's
own data, only--the product is certainly targeted to large
enterprises. For smaller projects, SAS/JMP is a good choice, with
student pricing starting from about $100.
