Populator's are used to populate or convert the Data models objects into data transfer objects(DTO).

Reverse Populator's are used to populate or convert the Form data Objects or dto into model Objects. While registering any user it captures the data in the Form Object(RegisterForm) then reverse populator do the conversion or population of this Form object to Model Object.
