Various architectures noted

Depending on how the data is stored and accessed, the various architectures are:

  •  Independent data marts (IDM)
  • Data mart bus architecture with linked dimensional data marts (DBA)
  • Hub and Spoke Architecture (HAS)
  • Federated architecture (FED)
  • Centralized Architecture

One other way of classifying various Data warehouse architectures is by the number of middleware between the operational systems and the analytical tools. These would be – the single-layer architecture and the N-layer architecture.
