You can add multiple profile functions to a data
profile. Profile functions are calculations you perform on the source data that
return information about various characteristics of the source data. When you
add a function to a data profile, you can choose from the following types of
functions:
Source-level functions
Performs calculations on two or more columns in a
source, source group, or mapplet group. For example, you can evaluate a
business rule for groups in an XML source.
Column-level functions
Performs calculations on one column of a source. For
example, you can evaluate the data in a column to find patterns that frequently
occur in the data.
Intersource functions
Performs calculations on two or more sources. These
functions generate information about the relationship between the sources. For
example, you might compare the values of columns in two sources to determine
the percentage of identical data that appears in both sources.Each function
type has a subset of functionality that you can configure when you add a
function to the data profile.
