Recording Contacts by using multiple webforms for two different services

Recording Contacts by using multiple webforms for two different services

I couldn't understand that how we record data from two different webforms and automatically separate them in 'Contacts' module.

Scenario: We are managing two different businesses with separate websites. For this purpose two different web forms have been created along with two pipelines. By catching data from clients at these sites, how can we differentiate and automate records in 'Contacts' and 'Deal'. Please guide me the workflow to do it efficiently and effectively.
