1. A computer-implemented method of providing an electronic target document in a data communication network, the method comprising: providing, by a first domain on a first server system, a link to open a digital first form in the first domain; receiving, by the first domain, an activation of the link by a user from a user computer device; redirecting, by the first domain, to a second domain on a second server system upon activation of the link, and providing a digital second form in the second domain, the second form comprising a retrieval field whereby, when the retrieval field is activated by the user from the user computer device, the second domain is configured to perform the following steps: providing a plurality of domain access fields; receiving an activation of a selected one of the domain access fields by the user from the user computer device; accessing a third domain on a third server system linked to the selected domain access field; and retrieving target document data from the third domain, uploading, by the second domain, the target document associated with the target document data to the first form of the first domain.
