A query is like asking a librarian to find a specific book in a library. It's a request for data or information from a database, which is like a digital library full of organized information. When you have a question or need specific data, you create a query, which is like telling the librarian exactly what book you're looking for. The database then searches and retrieves the relevant information for you. It's a bit like using a search engine to find answers on the internet. Queries are used to fetch the right data from databases, making it easier to find and use the information you need.
