System of record

A system of record is like a filing cabinet where you keep important documents, but it's digital. It is a computer system that is used to store and manage data that is important for a business or organization. It can store lots of different types of data like numbers, dates, times, names, and special instructions on how to do things. This data can be used to help the business or organization run more smoothly and efficiently.
