Abstract
Heterogeneous data at a plurality of remote nodes is accessed automatically in parallel at high speed from a user site using a simple script request containing a data source object name wherein the heterogeneous data is treated as a single data source object, the script further containing code representing a user-defined program to be executed on the data source object. The user-defined program may be represented by an embedded script, a user-defined script or an executable program designation. A user site agent breaks the user-generated script into new scripts appropriate for execution at the remote nodes. A messenger process transmits the new scripts to the appropriate remote nodes where respective agent processes respond to automatically access the appropriate data and to automatically execute the specified program. If the program is a user-defined script or executable, the respective agent processes access a metadata repository to obtain the specified program.
