Investopedia explains 'Data Warehousing'
Businesses might warehouse data for use in exploration and data mining, looking for patterns of information that will help them improve their businesses. A good data warehousing system can also make it easier for different departments within a company to access each other’s data. For example, a data warehouse might allow a company's CEO to easily exame the sales team’s data and help him to make decisions about how to improve sales or streamline the department. Effective data storage and management are also what make things like making travel reservations and using automated teller machines possible.
A key book on data warehousing is W. H. Inmon’s "Building the Data Warehouse", which was first published in 1990 and has been reprinted several times since.
