Data Warehouse is used to analyze data for businesses. Data Warehouse is a type of database that integrates the copies of transaction data from disparate source systems and provisions them for analytical use.For example, source A and source B may have different ways of identifying a product, but in a data warehouse, there will be only a single way of identifying a product.
