Layman’s Example of BigData

Suppose I own a grocery store which is monitored by cameras .
So what would I have at the end of the day ?A really huge collection of video footage ,which is nothing but data and a months footage ? That is enormous amount of data.
Now instead of just dumping the data onto storage ,what about making some money out of it ?
So what I will do is that I will try to find out patterns in the video footage e.g which are the products in which the consumers is more interested . Then I can predict with a better degree of accuracy what quality of product should I sell and which is the time when the demand for a product is maximum . So at the end of the day,this enormous amount of data has give me the capacity to organise the business better,increase customer satisfaction and thus make more money.This is #BigData .
