Data warehouse is a repository of data and related information whose purpose is to allow the extraction, reconciliation and the re-organization of data stored in traditional operational databases. This paper presents the data warehouse architecture for one-level, two-level, three-level classical, and novel three-level architecture with their critiques and the potential areas for future work. The architecture proposed so far exhibits some drawbacks when applied to work over large number of heterogeneous data sources. This paper addresses the issues of classical architecture of data warehouse as well as it presents the architecture for next generation typical data warehouse.
