CONNECTION ESTABLISHMENT ASSISTANCE SYSTEM

A connection establishment support system includes: a company classification unit 15 that classifies companies, as seen from a specific user, into a first type of company connected as an individual person, a second type of company connected as a company, and a third type of company having no connection either as an individual person or as a company; a type-based connection request unit 17 that performs a connection request using different methods depending on the type of company classified; and a connection update unit 14 that, when a manipulation for permission is performed by an individual person receiving the connection request, additionally stores connection information representing a relationship of new connection between the specific user and the individual person who performs the permission in a connection information storage unit 22. It is possible to perform a new connection request using different methods by classifying companies into three types depending on a connection method between companies and between individual persons, and establish a new connection in response to permission performed by the individual person receiving the request.
