Definition

Number rollup algorithm is a form of generalization that allows a user to set a range of numerical values for the input of numerical data in order to ensure a generalized value will be outputted.

Purpose

The purpose of a Rollup Data Masking component is to achieve greater control of the output distribution of values. In particular, it allows the user to preserve or change the shape of the output data statistical distribution.

Description

The Masking Date Rollup data masking component getsGets a sub-range of the values from the finite predefined range of date values and allows to map the dates within this sub-range into the chosen by user, specified date value. There is a default date for any values not determined via date ranges.

Usage Instructions:

1. Configure a source that contains the column with dates.alphabetical and numeric characters. The data in the column may also include any other character that will be treated as a separator.
2. Drag and Drop Masking DateNumber Rollup component, connect the source and the Masking DateNumber Rollup component with the source's precedence constraint.
3.Now, the precedence constraint (the blue arrow) passes proper meta-data to the Masking DateNumber Rollup component. If you click on the constraint, you will see:
4. Now that the metadata for the Masking DateNumber Rollup exists, and values are passed into the data masking component, please open the component editor:
5. In the second tab, there are input columns. Please check-mark only one column, the one that you will be masking with Masking DataNumber Rollup algorithm:
6. This will create an extra column with the prefix “Masked_”.
7. Create a connection manager for the destination and configure the source component for the destination. In the connection manager, in the tab “Mappings”, specify that you want the newly-created Field_Masked to be a field replacing the original value. For that, just click on the available input columns, choose the masked value, and map to the “Available Destination Columns”
8. Now, all the configurations are complete for the valid values. You can run the package with the Masking DateNumber Rollup component, and see the results of data masking.
