Data Mining
Data Mining :
Data Mining is the process of automatically discovering useful information in large data respositories.
Data mining techniques are deployed to scour large databases in order to find novel and useful patterns that might otherwise remain unknown.
They also provide capabilites to predict the outcomes of a future observations, such as predicting whether a newly arrived customer will spend more than $100 at a department store.
Not all information discovery tasks are considered to be data mining.
It is an integral part of knowledge discovery database (KDD), which is the overall process of converting raw data into useful information.
The input data can be stored in a variety of formats and may reside in a centralized data repository or be distrubuted across ,multiple sites.
The purpose of preprocessing is to transform the raw input data into an appropriate format for subsequent analysis.
Data preprocessing is perhaps the most laborious and time-consuming step in the overall knowledge discovery process.
