Data warehousing has been around for a number of years. In
those years, we have seen a lot of evolution happen in both software and
hardware that supports data warehousing. More and more features are being added
to new database management systems to increase performance and streamline the
data warehouse development lifecycle.
There has been a growing demand for integrating your data
warehouse more tightly with your operational systems. In the beginning of data
warehousing it was common that the data in a data warehouse would be out of date
from the operational system by a day, a week, or even a month. Now people are
expecting to make business decisions on data that is more up to date. This
thirst for more timely data has led the way to develop new interfaces through
Web Services and the Service oriented architecture.
The Data Warehousing Institute (TDWI ) has conducted
research to help data warehouse architects understand the latest trends in how
data warehouses are being supported. By understanding the trends, architects
can better plot their future architecture for their data warehouse environment.
By reading this research paper, you will have a better understanding of the
different options that are available today to support data warehousing. Make
sure you position your organizations data warehouse environment to support your
future data requirements.
