What is Data ware Housing?
Data Warehousing is a
process to properly assemble and manage data from various sources to answer
business questions not previously possible or known. A Data Warehouse has a
centrally located logical architecture which minimizes data synchronization
hence provides a single view of the business. A Data Warehousing is a
subject-oriented, integrated, time-variant, and non-volatile collection of data
in support of management’s decision-making process.
