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 In the beginning of data warehousing it was common that the data in a data warehouse would be out of date from the operational system by a day, a week, or even a month.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.
