The Computer Revolution/Databases/Data Warehouses

Data Warehouses are a large and specialized form of a database that is used to store a company's data in a form that can be easily updated and analyzed. With the advent of the data warehouse the need for heaps of physical records in innumerable filing cabinets largely ceased. No longer to modify physical paper records one by one, or to sort through masses of records to arrive at the data required. Data Warehouses can perform all of the complex queries and data mining that a regular database can.
