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.

Method and apparatus for automatic execution of concatenated methods across multiple heterogeneous data sources

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. A set of complex transactions may be built up and executed by simply touching or updating the special device screen, according to a visual methodology in which the results of each sub-transaction are displayed and become the basis for the next point and touch operation in the sequence of transactions.

Special device access to distributed data

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.

Method and apparatus for high speed parallel accessing and execution of methods across multiple heterogeneous data sources

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.

Method and apparatus for high speed parallel execution of multiple points of logic across heterogeneous data sources

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.
