2. In the Pattern Definition section, edit the pattern definition, or change the selected database, or add other patterns specific to available databases using the [+] button.

   If the regular pattern is simple enough to be used in all databases, select Default in the list.

   When you edit a pattern through the analysis editor, you modify the pattern in the Talend Studio repository. Make sure that your modifications are suitable for all other analyses that may be using the modified pattern.
3. Save your changes.
