Abstract
A single system image is provided for a parallel data warehouse system by exposing a shell database within a database management system comprising metadata and statistics regarding externally stored data. Further, functionality of the database management system can be exploited to perform pre-execution tasks. In one instance, one or more execution plans can be generated by the database management system for an input command and subsequently employed to generate a distributed execution plan.
