The beginning of the WWW was at the European Organization for Nuclear Research (CERN). Tim Berners-Lee built a database, in which you had to link every new page to an existing page. What is the name of this database?

ENQUIRE database system

Explanation:

Tim Berners-Lee developed the ENQUIRE database for the European Organization for Nuclear Research (CERN) in 1980. The ENQUIRE was a hypertext software program. ENQUIRE worked by using cards and hyperlinks between them in a similar manner than the internet (WWW) uses pages. The problem with ENQUIRE was that it was a close system that needed continuous manual updates. Simply too much time was needed to keep ENQUIRE's data updated. The CERN team realized that they needed a similar program but open to external users.
