When considering business value, it is worthwhile noting that there is a symbiotic
relationship between tactical decisions and strategic decisions. Fig. 16.1.8 depicts this
relationship.
Fig. 16.1.8 Where different activities occur.Fig. 16.1.8 shows that—for the most part—tactical activities and transactions occur in
the application environment. And strategic activities and decisions occur in the data
warehouse and the data mart environment. A cycle of processing occurs between the
two.
Transactions are run in the application environment. Data are produced as a by-product
of those transactions. The data find its way into the data warehouse. The data in the data
warehouse and the data mart are studied, and new decisions are made. The new decisions
have an impact on the transactions that are run. In turn, a new set of transactions are run,
and their data are stored in the data warehouse.
This cycle of data has a profound impact on the business of the corporation.
