Well, in my hobby of genealogy it's all about building a knowledge graph. Not just the obvious of who are children to which parents etc, but also where great-grandpa was in 1920. People reach for a database, and of course you need that, but for one thing the data certainly doesn't always come in a nice tabular format, and moreover you often don't know which piece of knowledge will become relevant for a question you care about - maybe two people worked together at the Kings Bay Mining Company, and then the was there accident in 1962, but uncle Hans was inspector at Wilhelmsen etc. Often you make progress because you remember niche geographical or historical information.
