CHAPTER FOUR

DESIGNING THE MINING DATA MART
The success of a data mining project strongly depends on the breadth and quality of the available data. That is why the data preparation phase is typically the most time-consuming phase of the project. In the following sections we will deal with the issues of selecting, preparing, and organizing data for data mining purposes.
Data mining applications should not be considered as one-off projects but rather as continuous processes, integrated into the organization’s marketing strategy. Data mining has to be “operationalized.” Derived results should be made available to marketers to guide them in their everyday marketing activities. The results should also be loaded into the organization’s front-line systems in order to enable “personalized” customer handling.
