Data Governance is like a set of rules that help organizations understand how they should store and use their data. Like when you play a game with your family, you need rules to make sure everyone knows what to do and how to keep the game fair. The same idea applies to organizations, like companies, which have a lot of data that needs to be used in a safe and fair way. Data Governance provides guidelines for how to store and use data, so that everyone knows how to do it without creating any problems.
