ABSTRACT:
A virtual data warehouse (the functional equivalent of a conventional data warehouse) that provides aggregated views of the complete data inventory. The virtual data warehouse contains metadata, which is used to form a logical enterprise data model that is part of the database of record (DBOR) infrastructure. Each legacy back-end database system is published on the infrastructure, with its metadata extracted and used as noted above. The infrastructure software uses standard J2EE, JMS and reusable EJBs, for transactional unit requests, and ETL (extract-transform-load) tools for real-time bulk loading of data.
