The Teradata Concept of the Data Warehouse
The data warehouse as conceived by Teradata is a dynamic process. The Teradata data warehouse is an active data warehouse that supports the ongoing, day-to-day business of the living enterprise, including many aspects of the traditional operational data store. Enterprise business rules are isomorphic with the rules of the data warehouse. Its most characteristic attribute is its volatility. The Teradata data warehouse is a dynamic entity.
In summary, the heart of the data warehouse is your data modeled in such a way that it matches your business. Just as the warehouse is used as a tool to change the business, so it must change over time if it is to continue to be a critical tool for supporting the enterprise. A true data warehouse sows the seeds that force its own change. The only static warehouse is the warehouse with little or no value to the business.
