Berkeley DB

Berkeley DB is like a big book where you can write things down and come back to them later. You can write your name, your favorite color, or even your favorite animal. But when you come back to the book, you can find what you've written down really fast because everything is organized in a special way. People use Berkeley DB to keep track of important things like money they owe or their work schedule. It's like a super helpful tool to help people remember and find things easily.
