Information Processing − A data warehouse allows to process the data stored in it. Data warehouse, a term coined by William Inmon in 1990, refers to a logically centralized data repository where data from operational databases and other sources are integrated, cleaned and standardized to support business intelligence. A database was built to store current transactions and enable fast access to specific transactions for ongoing business processes, known as Online Transaction Processing (OLTP). Since data lakes are rarely managed and supported to the degree of the data warehouse, Kaluba added, “the data functions or business needs they best support include exploratory analytical functions where raw, unrefined, and largedata is used to test new algorithms, identify … Databases .
