Data doesn’t sit still. A customer’s order becomes an invoice. It gets stored in a database. It gets analyzed for sales trends. Then it gets archived for tax compliance.

This chapter walks you through the whole data lifecycle, showing exactly how governance tools and decisions are applied at every single stage.
