The State has a requirement for a highly robust and secure data warehouse with:an efficient extract, transform, load (ETL) architecture that can support high-volume imports of multiple data files in multiple formats at rapid speeds and a set of common data structures that used across the data streams and externally available for 3rd parties and a self-service architecture to support web access to raw data sets, generated queries, and higher level standard reports based on the data held in the data warehouse (via web services, etc.).
