Major database vendors like Oracle and SQL incorporate data mining algorithms, such as clustering and regression tress, to meet the demand for data mining. While usually I don't even open them due to the volume that I get each day, this one was actually very interesting, thus I'm sharing it with you. What is important is knowing: what questions you want to answer, what you need the output to look like. Although data mining is a relatively new term, the technology is not.

NCBI2R is an R package to annotate lists of SNPs, genes and microsatellites. By contrast, unstructured data is not relational and doesn't fit into these sorts of pre-defined data models. With that in mind, here is a list of the differences: SQL DB has a limit of a 1TB database size. The process of drill-down analyses begins by considering some simple break-downs of the data by a few variables of interest (e.g., Gender, geographic region, etc.).
