Data warehousing is the process of extracting data from different databases and creating a store house of data that is specifically structured for querying and reporting. Data warehousing process includes coordination, planning, designing and periodic copying/extracting of data from various sources, both inside and outside the enterprise, into another database that is optimized for analyzing and information processing.Developing a data warehouse first starts with developing a system to extract data from different platforms/operating systems and ends with installation of a database warehousing system.
Data warehousing offers flexibility to managers to access the data using queries. This easy access to complicated data enables effective business analysis and business forecasting, which in turn provides great insight on various trends and supports in faster and better decision making.

What is the difference between data warehousing and data mining?
Data warehousing is the process of copying/extracting data from different databases and structuring a store house of data that can be used effectively for generating specific reports. Whereas, data mining is the process of analyzing the data from databases or data warehouse using queries and generating trends or observations that assists in taking stock of the current situation and planning future strategies.
