Wikidata provides factual data in the form of a central repository that can be used over in different Wikepedia articles without requiring a manual edit of all the articles where it has been used if there is a change in the underlying data. Editors of different articles on Wikipedia can simply embed the information available on Wikidata viz. ID of movie on IMDB, population of a city, etc. and if changes are made to data in Wikidata, they will be automatically reflected on the Wikipedia articles."
