Data warehouse

Data warehousing emphasizes capturing data from various sources for useful analysis and access, but not generally emanate from the point of view of the end user who may have access to specialized and sometimes require local databases. This last idea is known as the data mart.

There are two ways of data warehousing, top-down and bottom-up. The top-down approach spins off data marts for specific groups of users after the entire data warehouse was created. The bottom-up approach to building data marts and then combines them into a single, comprehensive data warehouse.

Typically, a data warehouse housed on a mainframe enterprise server or increasingly, in the cloud. Data from various online transaction processing (OLTP) applications and other sources is selectively extracted for use by analytical applications and the user queries.

The data warehouse term was coined by William H. Inmon, known as the Father of Data Warehousing. Inmon described a data warehouse as a subject-oriented, integrated, time-variant and non-volatile collection of data that supports the decision-making of management.
