How to change/Apply Alias of column in Pipeline

What is an Alias?​

Users can change alias datasets or table columns using an alias. The alias should be useful in the case where the user wants to show a different column name in the GUI rather than what name coming from the database. This might be required in case Business users do not concern about naming conventions used in the development process they want Different names to display.
