IFA Information Services
The IFA information services are based on the main and key objects in the IFA database. The central main object is the article.
A number of attributes are assigned to the article (e.g. prices) as well as further main objects linked to the article (e.g. address). Some of the attributes are mapped as Key Values (e.g. various indicators for the VAT rate), whose meaning is revealed by Key Objects.
