Data Vault modeling is a way of organizing and storing data so that it can easily be used again and again. It's like a vault full of data, where all the important pieces of information are all together in one place. Data Vault modeling helps to make sure that data remains consistent, secure, and up-to-date. It also makes it easier to analyze and use the data without having to constantly re-enter it. The data is stored in databases and can be accessed quickly and easily, so that information can be retrieved and used right away.
