The data drilling is the technique, to transform the data and extract the needed information from database (or data warehouse) by performing various operations in relational, tabular or multidimensional data.
Both the data DRILL-IN and DATA-UP are techniques to navigate between levels of data. The data-DRILL-IN (also know as drill down) technique is used to navigate from most summarized data form to the most detailed data form. Whereas data DRILL-UP is just opposite of this, in this we navigate from most detailed information to the summarized information.
