Distributed Data Warehouse/ Data Mart architecture of Warehouse development


What is Distributed Data Warehouse/ Data Mart architecture of Warehouse development?

It provides a logical database layer mapping a unified logical data model to physical tables in the various data marts. And second it provides transparent querying of the unified logical database across data marts and data warehouses along with caching and joining services.

Leading tool providers supporting this architecture are Informatica, Carleton, and Sybase Adaptive Server
