Abstract

When plural processing programs for generating post-processing data which is a source of services to be provided are present, a relationship between post-processing data and a data group which is a source of the post-processing data is managed. The processing units acquire pre-processing data, execute given processing, and generate post-processing data as a result of the processing. At an opportunity to acquire the pre-processing data, a process ID indicative of ordering of the acquisition, and not updated before and after the given processing is allocated to acquired pre-processing data. The generated post-processing data is stored, and in extracting the post-processing data satisfying the given data search condition, the post-processing data having a process ID equal to or before the process ID that is latest in the post-processing data and oldest among the respective processing units is extracted from the post-processing data that satisfies the data search condition.

First claim

The invention claimed is:

1. A computer system, comprising:
a computer coupled to a storage device, a communication interface, and a non-transitory computer readable medium storing instructions, that when executed by the computer, cause the computer to:
execute a plurality of processing units that each acquire pre-processing data, each execute given processing on the pre-processing data, and each generate post-processing data as a result of the processing;
newly allocate a respective process identifier (ID) from among a plurality of process IDs for one of the plurality of processing units each time the one of the plurality of processing units is to acquire the pre-processing data, wherein the process IDs collectively indicate an order of acquisition of the pre-processing data by the plurality of processing units;
manage a process management ID table that includes information of the processing units in correspondence with the process IDs which have been allocated to the processing units when the pre-processing data has been acquired by the processing units, the process management ID table being managed in ascending order of the process IDs;
store the post-processing data generated by the processing of each of the plurality of processing units in the storage device in association with the corresponding allocated process IDs;
determine the post-processing data that satisfies a received data search condition from a search request source; and
extract the post-processing data associated with a same or earlier process ID than a first process ID that is earliest among the respective latest allocated processing IDs of the plurality of the processing units from the determined post-processing data that satisfies the data search condition, and output the extracted post-processing data to the search request source.

2. The computer system according to claim 1 ,
wherein the process IDs are information indicating respective times at which the processing units acquire the pre-processing data.

3. The computer system according to claim 1 ,
wherein the process IDs are managed in association with identification information of the plurality of processing units that acquire the pre-processing data.

4. The computer system according to claim 1 ,
wherein the non-transitory computer readable medium further stores instructions, that when executed by the computer, cause the computer to:
store dependency information indicating a dependency of the plurality of processing units, and
extract the post-processing data having a same or earlier process ID than a second process ID that is earliest among the respective latest allocated processing IDs of the processing units having the dependency from the post-processing data that satisfies the data search condition.

5. The computer system according to claim 1 ,
wherein the non-transitory computer readable medium further stores instructions, that when executed by the computer, cause the computer to:
store value management information that defines information indicative of a value of each of the generated post-processing data for each of the plurality of processing units, and
generate value information of the extracted post-processing data with reference to the value management information, output the extracted post-processing data when the value of the extracted post-processing data is a predetermined value or smaller to the search request source, and output the generated value information to the search request source when the value of the extracted post-processing data is larger than the predetermined value.

6. The computer system according to claim 5 ,
wherein the non-transitory computer readable medium further stores instructions, that when executed by the computer, cause the computer to:
receive a request for acquiring the extracted post-processing data from the search request source after outputting the generated value information, and transmit the extracted post-processing data corresponding to the generated value information to the search request source.

7. The computer system according to claim 5 ,
wherein the value of each of the generated post-processing data defined by the value management information is a price per unit data amount.

8. The computer system according to claim 6 ,
wherein the value of each of the generated post-processing data defined by the value management information is a price per unit data amount.

9. The computer system according to claim 1 , further comprising:
a data storage computer, coupled to the computer, having a storage unit that stores the pre-processing data acquired by the plurality of processing units,
wherein the storage unit includes an external data acquisition unit that acquires the pre-processing data stored in an external computer connected thereto through a communication line, and stores the acquired pre-processing data in the storage unit when the plurality of processing units request to acquire the pre-processing data.

10. The computer system according to claim 9 ,
wherein the data storage computer further includes a data format conversion unit that converts the pre-processing data acquired from the external computer into a another data format.

11. The computer system according to claim 10 , wherein the non-transitory computer readable medium further stores instructions, that when executed by the computer, cause the computer to:
store data acquisition schedule information in which timings at which the plurality of processing units acquire the pre-processing data stored in the storage unit of the data storage computer is defined for each of the processing units, and
acquire the pre-processing data on the basis of the data acquisition schedule information.

12. A data management method for a computer system including a plurality of processing units that each acquire pre-processing data, each execute a given processing on the pre-processing data, and each generate post-processing data as a result of the processing, and transmit a search result in response to a request for searching the post-processing data,
the method comprising:
newly allocating a respective process identifier (ID) from among a plurality of process IDs for one of the plurality of processing units each time the one of the plurality of processing units is to acquire the pre-processing data, wherein the process IDs collectively indicate an order of acquisition of the pre-processing data by the plurality of processing units;
managing a process management ID table that includes information of the processing units in correspondence with the process IDs which have been allocated to the processing units when the pre-processing data has been acquired by the processing units, the process management ID table being managed in ascending order of the process IDs;
storing the post-processing data generated by the processing of each of the processing units in a storage device in association with the corresponding allocated process IDs;
determining the post-processing data that satisfies a received data search condition from a search request source; and
extracting the post-processing data associated with a same or earlier process ID than a first process ID that is earliest among the respective latest allocated processing IDs of the plurality of the processing units from the determined post-processing data that satisfies the search condition, and outputting the extracted post-processing data to the search request source.

13. A non-transitory computer readable recording medium storing a program for causing a computer system having a plurality of processing units to each execute processing to acquire pre-processi
