How databases work

A database is like a big book. It has information that is organized like a library. It stores all the data in one place, like a big filing cabinet. You can look up information quickly and easily. For example, let’s say you wanted to find the birthdate of your friend. You would look in the database and type in their name. The database would search through all the information it has stored and give you the answer. It’s like a giant search engine! When you go to a website, it often uses a database to help it show you the information you’re looking for. This is why it only takes a few seconds to look up something. Databases have been around for centuries. The first databases were used in Ancient Greece to keep track of ships and their cargo. Fun fact: the biggest database in the world is called the Human Genome Project. It has over 3 billion pieces of data!
