SQL 2008 Metadata-Driven ETL Whitepaper.
Platform Architecture
The design goals of the platform include improving the productivity of developers, enforcing ETL standards, supporting a cost-effective way to deploy large data warehouses on commodity hardware, and providing a centralize metadata repository for lineage tracking. The solution architecture of the platform is shown in Figure 1. The intent of this paper is not to document all the implementation details. Rather, it describes the concepts and key components of the platform and how they are connected with SQL Server Integration Services. For a more detailed architecture diagram, see Figure 6 at the end of this paper.
