Use standardization strategies to create columns with standardized versions of input strings.
When you configure a standardization strategy, you add one or more operations. Each operation implements a specific standardization task.
You can add the following types of operations to a standardization strategy:
Replace Reference Table Matches With Valid Values
Replace strings that match reference table values with the "Valid" value from the reference table.
Replace Reference Table Matches With Custom Strings
Replace strings that match reference table values with a user-defined replacement string.
Remove Reference Table Matches
Remove strings that match reference table values.
Replace Custom Strings
Replace user-defined strings with a user-defined replacement string.
Remove Custom Strings
Remove user-defined strings.
You can change the order of operations. The order of operations can change the output of a strategy because each operation reads the results of the preceding operation.
