I am trying to come up with a brief definition of what data warehousing is. This is what I have so far and would like some comments/suggestions on it and how to make it better.


In researching about data warehouses, I have found several different definitions. A basic definition is that a data warehouse is “a copy of transaction data specifically structured for query and analysis.” Also, data warehousing market consists of tools, technologies, and methodologies that allow for the construction, usage, management, and maintenance of the hardware and software used for a data warehouse, as well as the actual data itself. Also, a very important item to realize is that data warehousing is not necessarily for the needs of "decision makers" or used in the process of decision making.
