What is Enterprise Data Mart architecture of Warehouse
development?
EDMA supports an incremental approach to the data warehouse
through data mart development by creating a shared framework for development.
The EDMA framework includes enterprise subject areas, common dimensions,
metrics, business rules, and data sources, all represented in a logically
common (but not necessarily physically centralized) Global Metadata Repository
(GMR).
Central to the architecture also, is a common data staging area
called a Dynamic Data Store (DDS) for extraction, transformation, and migration
results. A DDS stores, cleans, and transforms data extracted from operational
systems, and also prepares the data for loading into DSS data stores.
