How to get the Article name using business logic handlers

Hi

     In business logic handlers, I have separated all handlers in one class(saparate namespace)  apart from insert Handlers and updateHandlers.

Those handlers are in the common namespace , which all have the common logic for all articles. (for code optimization)

Here how I can ensure for which aritcle its calling this handlers?

And Using dataset I can get the record values only not able to get table/article name .
