do we have plugins for ETL products like informatica and teradata as well
There is no analyzer provided by SonarSource able to analyze Informatica or Teradata files.
Generally ELT products come with a UI where the user drap and drop widgets, link them together to describe how the data is transformed. These products produce XML-like files. If we imagine that SonarQube would be able to analyze these files, it would be complex for the user to link back the issue raised to the original representation of the data flow. On top of that, the format of these files is not frozen and could change at any time which would make the analyzer no longer working.
