An interactive user interface is disclosed. According to various
embodiments, the interface includes a first field and at least one
additional field. The first field lists a focal item and the at least one
additional field contains a listing of items related to the focal item.
Certain of the related items in the at least one additional field include
a hyperlink which, when activated by the user, causes the item
corresponding to the activated hyperlink to become a new focal item
listed in the first field, such that the at least one additional field
transitions to list items related to the new focal item. The focal item
may be, for example, an identifier corresponding to a company, and the at
least one additional field may contain a listing of identifiers
corresponding to companies that are customers, suppliers or competitors
of the focal item company.
