Pathweb

The Pathweb was the shared intelligence of the Daleks, containing information on their history and experiences.

History
In the Dalek Asylum, when several Dalek inmates attacked the Eleventh Doctor upon recognising him, Oswin Oswald hacked into the Pathweb and deleted all the information connected with the Doctor; wiping him from the memories of the Dalek race. (DW: Asylum of the Daleks)
