A data aggregator is like a big library where lots of information is kept in one place. Just like how you can go to a library and find lots of different books, a data aggregator collects information from lots of different places and puts it all in one big database. This can include things like news articles, social media posts, sales data, and more.
Think of it like this: you want to learn about dogs. Instead of going to lots of different places to find information about dogs, you can just go to the dog section of the library and find all the books about dogs in one spot. Similarly, a data aggregator collects information from lots of different websites, companies, and other sources and puts it in one big database so that people can easily access all of that information in one place.
Companies and organizations use data aggregators to collect information to help them make important decisions. For example, if a company wants to know how a certain product is selling, they can use a data aggregator to gather sales data from different retailers to see how much of the product is being sold in different places.
Overall, a data aggregator is like a big collection of information that brings together lots of different pieces of data from different sources so that people can easily find and use that information.
