This is a system that contains a very, very large list of persons. It could have their employment historial, as well as historial of big events on their lifes, as well as the relationships within these people.
It has a very, very large of organizations and how people is related to this organizations.
All this serves to find how people could be related to other people or organizations. Also servers to create black lists. Sort of intelligence, however, searching for intelligence system does not give me the results I expect in SE.
Do you have any idea of how are these kind of systems called? Also, if there are companies who sell these kind of systems? (I was told we would have to develope it).
