Data Patterns

Data Patterns

Data patterns are regular expressions that describe the format of source data in a data domain.
A data pattern can contain multiple data expressions. If any of the expressions match patterns of the data for a column, then the column belongs in the data domain. You can configure detailed regular expressions to identify data in columns.
For example, a Social Security number contains numbers in the following pattern:
999-99-9999
The following regular expression shows a data pattern that describes the format of a Social Security number:
[0-9]{3}-[0-9]{2}-[0-9]{4}
