Data network could be a private network (Local offices within a city or many cities in the same country/region and also using IPLC’s to connect other countries/continents) or on Internet by creating Hard/soft VPN tunneling in between the offices. In general discuss it is considered on the Internet only but it being used by creating point to point connect using Wireless or only data connectivity between two office.
