How big data can help vulnerable people manage their health and lives

What is big data anyway? There are many definitions. The simplest one I came across says that big data stands for information that goes beyond what could be squeezed into a large spreadsheet. Big data cannot be filled into a spreadsheet simply because it is no longer numbers. It includes words, visuals, pictures, videos and more. Add to that the enormous amount of information we share on social media platforms, Google searches, blog posts, online reviews, personal photographs, videos etc and you have the big mass that is big data, I was told.
