Patterns are sets of strings against which you can define the content, structure and
quality of high complex data. The Profiling perspective of Talend Studio lists two types of patterns:
regular expressions, which are predefined regular patterns, and SQL patterns which are
the patterns you add using
For more information about patterns, see Patterns.
Indicators are the results achieved through the implementation of different patterns. They can represent the results of data matching and different other data-related operations. The Profiling perspective of Talend Studio lists two types of indicators: system indicators, a list of predefined indicators, and user-defined indicators, a list of those defined by the user.
For more information about indicators, see Indicators.
