Data Warehouse Architecture


Data Warehouse definition by William H. Inmonna:

A data warehouse is a:

  • subject-oriented
  • integrated
  • timevarying
  • non-volatile

collection of data in support of the management's decision-making process.

A data warehouse is a centralized repository that stores data from multiple information sources and transforms them into a common, multidimensional data model for efficient querying and analysis.
