Wikipedia:Articles for deletion/Very large database
The topic is notable; for example, here's a book about one aspect of it: ''https://books.google.co.uk/books?id=xqbfBwAAQBAJ Mining Very Large Databases with Parallel Processing''.  To understand the general nature of this topic, see ''https://www.symmetrymagazine.org/breaking/2009/09/16/building-the-biggest-scientific-databases Building the biggest scientific databases''.  Notice that this uses synonyms such as "biggest" and "extremely large", so we should include those terms too.  This demonstrates that the dictionary definition argument for deletion is nonsense.  We are not dealing with a particular word here and there is no dictionary content – etymology, grammar and the like.  Per , what we have here is a |stub for a |broad concept.  Note that the page used to be larger but much of the content was |split to form the VLDB page.  That's about an annual conference which is devoted to this topic – the http://vldb.org/2019/ 45th will be next year in Los Angeles.  They publish their proceedings each year and so that's another stack of potential sources.  As it happens, I shall myself be attending a https://www.eventbrite.co.uk/e/cambridge-wikimedia-meetup-tickets-49847099015?utm-medium=discovery&utm-campaign=social&utm-content=attendeeshare&aff=escb&utm-source=cp&utm-term=listing Wikimedia event tomorrow in Cambridge organised by
