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 at least one method to be performed on the data source object and at least a second method to be automatically performed on the results of executing the first method. A user site agent breaks the user-generated script into new scripts appropriate for execution at the remote nodes and determines whether the second method should be executed at the remote nodes or at the user site. 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 methods.

Abstract: Methods are executed upon data objects distributed across a plurality of nodes of a system from a user-held “special” device (such as a cell phone, palm top, set top, car GPS system, . . . ). Heterogeneous data at a plurality of remote nodes is accessed automatically in parallel at high speed 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. An 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.

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 at least one method to be performed on the data source object. Respective agent processes at the user site and at the remote nodes automatically generate descriptor files containing metadata corresponding to the data source object. The 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 execute specified methods upon it.

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.

Abstract: A number of partitions of a cellular multiprocessor (CMP) are connected to respective databases and form respective nodes of a data warehouse. Heterogeneous data stored across the 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 at least one method to be performed on the data source object. Respective agent processes are stored in memory dedicated to each partition and automatically generate descriptor files containing metadata corresponding to the data source object from a repository available to each partition. A messenger process transmits the new scripts to the appropriate nodes via memory-based messaging using a shared portion of the CMP memory. Respective agent processes at each node respond to automatically access the appropriate data and execute specified methods upon it.
