Follow along with data modeling expert Dirk Lerner and learn the approaches for managing time and history in a data warehouse.
“Over time, things change - things like customers, products, accounts, and so forth. But most of the data we keep about things describes what they are like currently, not what they used to be like. When things change, we update the data that describes them so that the description remains current. But all these things have a history, and many of them have a future as well, and often data about their past or about their future is also important.” – Tom Johnston
