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.

* SQL patterns which are the patterns you add using LIKE clauses.

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.

* User-defined indicators, a list of those defined by the user.
