Abstract
Abstract An enhancement for a data processing system including a relational database provides storage of at least a first command corresponding to each of a plurality of tasks which can be automatically performed. In response to an event or conditions in the data processing system, such as an operation in the relational database, a task is selected and the first command and additional task lines are output. These lines are assembled with arguments derived from conditions or operations in the system such as arguments of the relational database operation. Additional events and system conditions may be imposed for task selection, imposing conditionality and chaining of plural tasks. Immediate execution of a selected task is accomplished by selectively inserting a first command of the task in exit code of another application executable on the data processing system. A parser is provided to select parameters and assemble the parameters with task lines as arguments thereof.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
99 words
A data processing system including, in combination, a relational database, means for detecting at least one of an in said relational database or a condition in said relational database, means for storing at least a first command corresponding to each of a plurality of tasks, means responsive to said means for detecting at least one of an event or a condition in said relational database for selecting said first command corresponding to one of said plurality of tasks, and means for outputting said first command to a portion of said data processing system for execution of said first command.
Claim 2
Dependent Claim
99 words
A data processing system including, in combination, a relational database, means for detecting at least one of an in said relational database or a condition in said relational database, means for storing at least a first command corresponding to each of a plurality of tasks, means responsive to said means for detecting at least one of an event or a condition in said relational database for selecting said first command corresponding to one of said plurality of tasks, and means for outputting said first command to a portion of said data processing system for execution of said first command.
Claim 3
Dependent Claim
27 words
A data processing system as recited in claim 1, further including means for assembling a parameter with said first command as an argument of said first command.
Claim 4
Dependent Claim
26 words
A data processing system as recited in claim 2, further including means for deriving said parameter from arguments of another command in said data processing system.
Claim 5
Dependent Claim
28 words
A data processing system as recited in claim 2, further including means for storing said first command to be executed by a processor in said data processing system.
Claim 6
Dependent Claim
34 words
A data processing system as recited in claim 2, further including means for storing said first command in exit code for an operation executable on at least a portion of said data processing system.
Claim 7
Dependent Claim
20 words
A data processing system as recited in claim 2, wherein said first command specifies a return to a user application.
Claim 8
Dependent Claim
60 words
A data processing system as recited in claim 2, further including means for retrieving additional lines of code from said means for storing at least a first command corresponding to each of a plurality of tasks, said additional lines corresponding to a task selected by said means for selecting said first command corresponding to one of said plurality of tasks.
Claim 9
Dependent Claim
54 words
A data processing system as recited in claim 2, wherein said means for selecting said first command corresponding to one of said plurality of tasks further includes means for selecting said first command in response to at least one further event or further condition in addition to said at least one event or condition.
Claim 10
Dependent Claim
28 words
A data processing system as recited in claim 1, further including means for storing said first command to be executed by a processor in said data processing system.
Claim 11
Dependent Claim
34 words
A data processing system as recited in claim 1, further including means for storing said first command in exit code for an operation executable on at least a portion of said data processing system.
Claim 12
Dependent Claim
20 words
A data processing system as recited in claim 1, wherein said first command specifies a return to a user application.
Claim 13
Dependent Claim
60 words
A data processing system as recited in claim 1, further including means for retrieving additional lines of code from said means for storing at least a first command corresponding to each of a plurality of tasks, said additional lines corresponding to a task selected by said means for selecting said first command corresponding to one of said plurality of tasks.
Claim 14
Dependent Claim
54 words
A data processing system as recited in claim 1, wherein said means for selecting said first command corresponding to one of said plurality of tasks further includes means for selecting said first command in response to at least one further event or further condition in addition to said at least one event or condition.
Claim 15
Independent Claim
90 words
A method of automatically spawning tasks in a data processing system including a relational database, said method including the steps of storing at least a first command corresponding to each of a plurality of tasks, sensing at least one of an event or a condition in said relational database, selecting a task in response to said at least one event or condition, adding at least one of an argument and a return specification to said first command, and executing said at least first command in response to said selecting step.
Claim 16
Independent Claim
90 words
A method of automatically spawning tasks in a data processing system including a relational database, said method including the steps of storing at least a first command corresponding to each of a plurality of tasks, sensing at least one of an event or a condition in said relational database, selecting a task in response to said at least one event or condition, adding at least one of an argument and a return specification to said first command, and executing said at least first command in response to said selecting step.
Claim 17
Dependent Claim
32 words
A method as recited in claim 14, including the further step of selecting said argument in response to at least one of and event and a condition in said data processing system.
Claim 18
Dependent Claim
29 words
A method as recited in claim 14, including the further step of inserting said first command in another operation executable by said data processing system as exit code thereof.
Claim 19
Dependent Claim
25 words
A method as recited in claim 14, including the further step of extracting said argument from an operation to be performed on said relational database.
