This document provides an overview of the typical architecture for an enterprise data warehouse. It discusses the core components, which include source systems, a transactional repository to store integrated data, a staging area for data loading, and data marts for analysis and reporting. It also describes additional elements that may be needed like ETL tools, data quality tools, a metadata repository, and documentation requirements. The goal is to present a design pattern for organizations to follow when implementing a large-scale enterprise data warehouse solution.
