Data processing apparatus, computer-readable storage medium, system, and data processing method for improved event processing

A non-transitory, computer-readable storage medium having stored thereon a program that causes a computer to function as:

• a data receiving unit configured to receive data;
• a set data recording unit configured to record a plurality of set data, each of the plurality of set data being obtained by combining a corresponding one of a plurality of events with a corresponding one of a plurality of first programs, each of the plurality of set data also including identifying information regarding any others of the plurality of events associated with the corresponding one of the plurality of events, the corresponding one of the plurality of first programs being started when each of the corresponding one of the plurality of events and any others of the plurality of events associated with the corresponding one of the plurality of events have been generated by a respective one of a plurality of second programs by processing the data obtained by the data receiving unit, the corresponding one of the plurality of first programs processes the corresponding one of the plurality of events and any others of the plurality of events associated with the corresponding one of the plurality of events to generate a corresponding one of a plurality of resulting events;
• and
• a data processing execution unit configured to execute the plurality of first programs, each of the plurality of first programs being configured to process at least two respective events from among the plurality of events and the plurality of resulting events,
• wherein the computer further comprises a memory, and wherein when one of the plurality of second programs processes the data obtained by the data receiving unit to generate one of the plurality of events, the one of the plurality of events generated by the one of the plurality of second programs is stored in a non-transitory storage medium and the data that has been processed and the one of the plurality of second programs are deleted from the memory to reduce a required amount of memory, and
• wherein the program causes the computer to function such that each of the plurality of first programs is capable of processing corresponding ones of the plurality of events and the plurality of resulting events regardless of the order in which the corresponding ones of the plurality of events and the plurality of resulting events are generated and regardless of the time interval between the generation of each of the corresponding ones of the plurality of events and the plurality of resulting events.

A data processing method that is executed by a computer, wherein the computer executes instructions that cause the computer to comprise a set data recording unit and a data receiving unit, the data processing method comprising:

• recording, in the set data recording unit, a plurality of set data, each of the plurality of set data being obtained by combining a corresponding one of a plurality of events with a corresponding one of a plurality of first programs, each of the plurality of set data also including identifying information regarding any others of the plurality of events associated with the corresponding one of the plurality of events, the corresponding one of the plurality of first programs being started when each of the corresponding one of the plurality of events and any others of the plurality of events associated with the corresponding one of the plurality of events have been generated by a respective one of a plurality of second programs by processing the data obtained by the data receiving unit, the corresponding one of the plurality of first programs processes the corresponding one of the plurality of events and any others of the plurality of events associated with the corresponding one of the plurality of events to generate a corresponding one of a plurality of resulting events;
• and
• executing the plurality of first programs, each of the plurality of first programs being configured to process at least two respective events from among the plurality of events and the plurality of resulting events,
• wherein the computer further comprises a memory, and wherein when one of the plurality of second programs processes the data obtained by the data receiving unit to generate one of the plurality of events, the one of the plurality of events generated by the one of the plurality of second programs is stored in a non-transitory storage medium and the data that has been processed and the one of the plurality of second programs are deleted from the memory to reduce a required amount of memory, and
• wherein each of the plurality of first programs is capable of processing corresponding ones of the plurality of events and the plurality of resulting events regardless of the order in which the corresponding ones of the plurality of events and the plurality of resulting events are generated and regardless of the time interval between the generation of each of the corresponding ones of the plurality of events and the plurality of resulting events.
