  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an example of a hardware configuration of an enterprise system to which the present invention is applied.

  As shown in the figure, the enterprise system includes a plurality of user terminal devices 1 (1a, 1b, 1c...), A data linkage system 2, a plurality of information systems 3 (3a, 3b, 3c. The plurality of on-site equipment systems 4 (4a, 4b, 4c...) And the synthesizing subsystem 5 are configured.

  In the present embodiment, the data linkage system 2 collects necessary information (source data) from the information system 3 or the field facility system 4 based on a request from the user terminal device 1 and follows a predetermined rule. Therefore, it is processed and combined and provided to the user terminal device 1.

  The user terminal device 1 is a terminal device for using the data of the company system, and can be used effectively by arranging it in a plurality of departments / organizations in the company. The user terminal device 1 has, for example, a Web browser function, and uses the Web browser to display information necessary for the data linkage system 2 to execute processing, for example, an identifier of a target product for which information is collected, a target period, and the like. The data collected, processed and synthesized by the data linkage system 2 can be acquired.

  The information system 3 serving as a source data provider has a function as a database for managing manufacturing information of products in a company, and a plurality of information systems 3 are provided depending on the management target. Items managed by the information system 3 can be, for example, “product ID”, “manufacturing date”, “product type”, “storage location”, etc., when the management target is “product management information”. Can be “product type”, “stock quantity”, “update date”, and the like.

  The information system 3 includes an information DB 31 for recording product manufacturing information and the like, an interface unit 32 for exchanging information with the data linkage system 2, and a backup DB 33 for recording backup data of the information DB 31.

  In other words, in the present embodiment, each information system 3 backs up the information DB 31 regularly or irregularly. When the backup is performed, the data linkage system 2 is notified of the backup information such as the backup target, the backup date and time, and the backup data storage destination. However, the backup DB 33 may be provided outside the information system 3.

  In addition to the information system 3, the on-site equipment system 4 serving as the source data source has a function as work processing equipment in the company, and a plurality of on-site equipment systems 4 are provided according to the contents to be processed. The work processing performed by the on-site facility system 4 can be, for example, product production, product processing, monitoring, and the like.

  The on-site equipment system 4 includes a work processing unit 41 that performs work processing, a data output unit 411 that outputs processing status data relating to work processing, an interface unit 42 that exchanges information with the data linkage system 2, and a data output unit. And a backup DB 43 for recording backup data of the processing status data output by 411. However, the backup DB 43 may be provided outside the field facility system 4.

  That is, in the present embodiment, each field facility system 4 performs backup of the processing status data output by the data output unit 411. When the backup is performed, the data linkage system 2 is notified of the backup information such as the backup target, the backup date and time, and the backup data storage destination. Since the processing status data output from the data output unit 411 of the on-site equipment system 4 indicates a series of processing statuses for a certain product of the on-site equipment system 4, the backup data has a property as processing history data. .

  The processing status data output by the data output unit 411 will be described more specifically. For example, when the work process is “heating process”, the item of the processing status data is “product ID” that identifies the product to be processed. “Time”, “Temperature”, etc. As a result, the temporal change of the heating temperature for the product specified by the “product ID” (for example, 456 degrees at 10:00, 565 degrees at 10: 1, 554 degrees at 10:02, ..., 10:30 heat treatment) End).

  The data linkage system 2 includes a user interface unit 21 for exchanging information with the user terminal device 1, a data processing unit 22 that specifies source data to be acquired, and processes and synthesizes the acquired source data. A data storage unit 23 for storing various data used by the data processing unit 22 and a source data acquisition unit 24 for exchanging information with the information system 3 and the field facility system 4 are provided.

  In the present embodiment, the data storage unit 23 includes a workflow model 210 that indicates the flow of work for each business handled by the enterprise system, information requested by the user terminal device 1, the information system 3 or the field facility system 4. In order to synthesize the data relation model 220 expressing the relationship with the source data provided by the source data, the source data processing rule 230 recording the processing rules of the source data, and the processed source data into a format provided to the user terminal device 1 The user-provided information synthesis rule 240 in which the above rule is recorded is stored.

  FIG. 2 is a block diagram for explaining the outline of the processing in the enterprise system by paying attention to the data relation model 220.

  As shown in the figure, the data relationship model 220 includes a plurality of user-provided information synthesis modules 221, a plurality of intermediate information creation modules 222, and a plurality of backup management information 223.

  The intermediate information creation module 222 and the backup management information 223 have a one-to-one correspondence with the information system 3 or the field facility system 4.

  Here, the intermediate information creation module 222 defines rules for processing source data acquired from the information system 3 or the field facility system 4 into intermediate information. The intermediate information is information that is composed of one or a plurality of intermediate information items and is a combination source of information that is finally provided to the user terminal. That is, one or more items included in a certain source data are processed into one intermediate information item. Depending on the intermediate information item, it is necessary to refer to old and new values or past values of the same source data. In this case, the backup management information 223 is used.

  FIG. 3 is a diagram illustrating a data configuration of the intermediate information creation module 222. As shown in the figure, the intermediate information creation module 222 includes an intermediate information creation module ID 2221 that is an identifier of the intermediate information creation module, a processing source data 2222, a processing unit 2223, and an intermediate information item list 2224. Yes.

  The processing source data 2222 is information for specifying the information system 3 or the on-site equipment system 4 corresponding to one to one. The information system 3 or the on-site equipment system 4 can be specified by name, ID, URL, and the like.

  The processing unit 2223 is information indicating the number of targets to which the intermediate information creation module 222 is applied. For example, when a certain intermediate information creation module 222 generates information on a manufacturing period related to a product that handles 20 pieces as one lot, “20” is determined as the processing unit 2223. In addition, when a certain intermediate information creation module 222 generates manufacturing date information for a specific product, “1” is set as the processing unit 2223. The processing unit 2223 is a fixed value according to the contents of the intermediate information creation module 222, but may be changeable based on a user instruction.

  The intermediate information item list 2224 is information indicating intermediate information items generated by the intermediate information creation module 222. For each intermediate information item, an intermediate information item name 2224a and an applicable source data processing rule 2224b are defined.

  The intermediate information item name 2224a is, for example, “lot production start date”, “lot production period”, “shipment date”, “product number”, “product number” when the source data is the information system 3 that manages “product management information”. In the case of the on-site equipment system 4 in which the date of goods receipt, “product type”, “storage location”, “number of stored items”, “stock quantity”, etc. are determined and the source data performs “heating process”, “product ID” “processing start time” "Heat treatment period", "Average heating temperature", etc. are defined.

  The applied source data processing rule 2224b is information for designating the source data processing rule 230 for generating a value corresponding to the intermediate information item name 2224a. Specifically, it is represented by an identifier of the source data processing rule 230.

  Some intermediate information item names 2224a can be used as they are without processing information included in the source data. For example, “Product ID”, “Product Type”, etc. The application source data processing rule 2224b is left blank for such intermediate information items that do not require processing.

  Here, a specific example of the source data processing rule 230 is shown in FIG. As shown in this figure, in the source data processing rule 230, an ID 231 which is a rule identifier, an intermediate information item name 232, a processing rule 233, and a target 234 are set.

  The intermediate information item name 232 indicates the intermediate information item name to which this rule is applied, and the target 234 is the information system 3 or the on-site equipment system 4 that is the source data to which this rule is applied. Each of them is convenient information for system operation, maintenance, etc., and may not necessarily be included in the source data processing rule 230.

  For example, assume that “manufacturing start date” is set as an intermediate information item name 2224a in an intermediate information creation module 222, and “M1” is set as an applicable source data processing rule 2224b.

  In this case, the processing rule 233 “the oldest value of the manufacturing date” specified by the ID 231 “M1” of the source data processing rule 230 is applied. That is, the oldest value among the items “manufacturing date” included in the source data indicated by the processing source data 2222 is used as the intermediate information item. Specifically, among the “manufacturing dates” of the products included in the target lot, the oldest value is processed as the “manufacturing date” of the lot.

  The source data processing rule 233 can be expressed in various forms such as a program and a calculation formula. A rule that refers to an external system may be adopted.

  Returning to FIG. 2, when the information system 3 or the field facility system 4 performs the backup process, the backup management information 223 acquires and records the backup information such as the backup target, the backup date and time, and the backup data storage destination. Is.

  Therefore, by referring to the backup management information 223, it is possible to acquire the data contents of the information system 3 or the output data of the field facility system 4 at a certain time or a certain period.

  Note that the backup process may use any method such as complete backup, differential backup, and incremental backup. Further, the backup information may be acquired by the backup management information 223 independently, or the information system 3 or the field facility system 4 may notify the backup management information 223.

  For example, it is assumed that “inventory quantity” is set as an intermediate information item name 2224a in an intermediate information creation module 222, and the inventory quantity of the target product in the past is required.

  In this case, referring to the backup management information 223, a backup file in which the number of stocks in the past for the target product is recorded is specified, and necessary information is acquired by accessing the backup file.

  Further, when obtaining “average target data within the operation period” as in the ID 231 “M6” of the source data processing rule 230, the backup management information 223 is referred to and all backup files including data within the target period are obtained. Identify and obtain necessary information by accessing each backup file.

  Thus, since the data linkage system 2 manages the backup information of the information system 3 and the field facility system 4 using the backup management information 223, it is possible to easily refer to past data. .

  The user-provided information synthesis module 221 is a module for synthesizing the intermediate information processed by the intermediate information creation module 222 into a format that is further provided to the user. The user-provided information synthesis module 221 has a hierarchical structure and may further synthesize the information synthesized by other user-provided information synthesis modules 221.

  FIG. 5 is a diagram showing a data configuration of the user provided information synthesis module 221. As shown in FIG. As shown in this figure, the user provided information composition module 221 has a composition module ID 2211 that is an identifier of the user provided information composition module, a composition module name 2212, a composition source list 2213, and a provision information item list 2214. is doing.

  The synthesis module name 2212 can be used as a keyword when searching for the user-provided information synthesis module 221 corresponding to information that the user intends to acquire, as will be described later. The synthesis module name 2212 can be, for example, “product management information and inventory record”, “heat treatment state and storage location”, and the like.

  The composition source list 2213 is information indicating other modules used for composition. Since the user provided information composition module 221 has a hierarchical structure, the composition source module is another user provided information composition module 221 or an intermediate information creation module 222.

  The provided information item list 2214 is information indicating items of user provided information generated by the user provided information synthesis module 221. A user-provided information item name 2214a, a composition source item list 2214b, and a composition rule 2214c are defined for each item.

  The user-provided information item name 2214a is, for example, “product ID”, “manufacturing date”, “product type”, “storage location”, “heat treatment period”, “when the composition module name 2212 is“ heat treatment state and storage destination ”. The average heating temperature ”can be used.

  The combination source item list 2214b is a list of items used when generating a value corresponding to the user provided information item name 2214a. Of the provided information item name 2214a of the user provided information composition module 221 designated in the composition source list 2213 and the intermediate information item name 2224a of the intermediate information creation module 222, a necessary item name is designated.

  The composition rule 2214c is information for designating the user provision information composition rule 240 for generating a value corresponding to the user provision information item name 2214a. Specifically, it is represented by an identifier of the user provided information synthesis rule 240.

  Here, a specific example of the user provided information synthesis rule 240 is shown in FIG. As shown in the figure, the user-provided information composition rule 240 is set with an ID 241 and a processing content 242 which are rule identifiers.

  For example, when “C1” is set as the synthesis rule 2214c, the oldest value among the values of the items indicated in the synthesis source item list 2214b is acquired. When “C2” is set as the synthesis rule 2214c, the newest value among the values of the items shown in the synthesis source item list 2214b is acquired.

  If “C” is set as the synthesis rule 2214c, it means that the subsystem is called. In this case, the URL of the subsystem to be called is designated. A plurality of subsystems for this purpose are prepared in the synthesis subsystem 5 of FIG.

  The sub-system, for example, provides the combined user-provided information “acquisition of heat treatment state and storage location” consisting of “product ID” “manufacturing date” “product type” “storage location” “heat treatment period” “average heating temperature” If the flag that warns against data with an average heating temperature over the reference value is added as an item, the reference value is managed by the subsystem, and this value is used when synthesizing the warning flag value. It can be used when calling a subsystem.

  As described above, the data linkage system 2 sets management / processing information peculiar to the information system 3 or the field facility system 4 in the backup management information 223 and the intermediate information creation module 222, and further uses the configuration and relationship. Is set in the user provided information synthesis module 221. The rule pattern actually used is recorded in the source data processing rule 230 and the user-provided information composition rule 240.

  For this reason, if there is a change in the configuration of the information system 3 or the on-site equipment system 4, the relevant information in the user-provided information synthesis module 221 and the intermediate information creation module 222 of the data relationship model 220 should be updated. It ’s enough. That is, the source data processing rule 230 and the user-provided information composition rule 240 need not be changed. Therefore, the burden of maintenance work in the enterprise system can be reduced.

  Returning to FIG. 2, the user terminal device 1 designates the provision information indicating the information to be acquired for the data relation model 220 storing the data as described above (arrow (1) in the figure). Here, the provision information includes information for designating the user provision information synthesis module 221. The designated user-provided information synthesis module 221 refers to the synthesis source list 2213 necessary for synthesizing the user-provided information, and identifies the intermediate information creation module 222 that creates intermediate information ((2 in the figure) ) Arrow).

  The identified intermediate information creation module accesses the associated source data (310, 410). At this time, the backup data (330, 430) is also accessed by referring to the backup management information 223 as necessary (arrow (3) in the figure).

  Then, information on the source data (310, 410) and backup data (330, 430) is acquired (arrow (4) in the figure). The acquired information is processed according to the applied source data processing rule 2224b and passed to the user provided information synthesis module 221 (arrow (5) in the figure).

  The user-provided information composition module 221 further processes the information according to the composition rule 2214c (arrow (6) in the figure), and finally transmits the synthesized information to the user terminal device 1 as user-provided information. (Arrow (7) in the figure).

  The user terminal device 1 relates to the work unit 211 by selecting the work unit 211 related to the acquired information with reference to the workflow model 210 when designating the user provided information synthesis module 221. The name of the user provided information composition module 221 can be acquired. Thereby, designation of the user-provided information synthesis module 221 can be facilitated.

  FIG. 7 is a diagram showing a data configuration of the work unit 211 constituting the workflow model 210. As shown in the figure, the work unit 211 has a work ID 2111, work name 2112, a previous work list 2113, a subsequent work list 2114, and a related synthesis module list 2115. The previous work list 2113 shows other work units 211 performed before the work unit 211, and the rear work list 2114 shows other work units 211 performed after the work unit 211. A unit of work 211 may be included. The other work unit 211 can be indicated by a work ID 2111.

  The work name 2112 can be, for example, “product inspection”. The work unit 211 can indicate the workflow model 210 indicating the flow of work by defining the previous work list 2113 and the subsequent work list 2114. In addition, by defining the related synthesis module list 2115, the user-provided information synthesis module 221 related to the work unit 211 can be shown by selecting the work unit 211.

  Next, the flow of processing in the data linkage system 2 of the present embodiment will be described with reference to the flowchart of FIG.

  The data linkage system 2 receives designation of information to be provided from the user terminal device 1 (S101). Here, the designation of the information to be provided includes designation of the user provision information synthesis module 221 and designation of the provision information designation parameter. Note that a search method of the designated user-provided information synthesis module 221 will be described later.

  FIG. 9 is a diagram illustrating a configuration example of the provision information designation parameter. In the example of this figure, the provision information target and the target period (date and time) are designated. Here, the provision information target can be, for example, the product ID of the target product. A plurality of product IDs may be specified. If the information provided by the user-provided information composition module 221 according to the designation is not in units of individual products but in units of lots, the processing of the intermediate information creation module 222 is performed from the designated product ID. Assume that the products for several lots determined in the unit 2223 are to be processed.

  The target period specifies the start date and time and the end date and time of information to be acquired. In addition, when only one of the start date and time and the end date and time is specified, the date and time is handled as an acquisition target.

  However, depending on the information to be provided, the provision information target or the target period may be unnecessary, and items other than the provision information target and the target period (date and time) may be used as the provision information specifying parameter.

  When the data linkage system 2 receives the designation of the information to be provided, the data linkage system 2 refers to the synthesis source list 2213 of the user provided information synthesis module 221 related to the designation, and creates an intermediate information creation module 222 that creates intermediate information necessary for the synthesis. Specify (S102).

  Then, with reference to the specified intermediate information creation module 222, source data is acquired according to the processing source data 222 (S103), and processed into intermediate information according to the applied source data processing rule 2224b (S104).

  The above intermediate information processing is performed for all intermediate information items shown in the user provided information item list 2214 of the user provided information synthesis module 221 (S105).

  When all the intermediate information items have been processed (S105: Y), values are synthesized in accordance with the synthesis rule 2214c for every provision information item shown in the user provision information item list 2214 of the user provision information synthesis module 221. (S106). At this time, an item for which “C” is defined in the synthesis rule 2214c is requested to be processed by the designated subsystem.

  Then, the synthesized user-provided information is output to the requesting user terminal device 1 (S107). Thereby, the user of the user terminal device 1 can acquire necessary information processed from the source data.

  Next, the search process of the user provided information synthesis module 221 designated by the user will be described with reference to the flowchart of FIG.

  In this embodiment, the data linkage system 2 provides the user with two methods as search processing of the user provided information synthesis module 221. That is, keyword search and workflow search. The user can select one of the search methods (S201).

  If the user selects keyword search, the keyword input from the user is accepted (S202). On the other hand, the user can input keywords related to necessary information.

  When the input of the keyword is received, the keyword is searched for the synthesis module name 2212 of the user provided information synthesis module 221 (S203). Note that a data item for keyword search may be separately provided in the user provided information composition module 221.

  And the information of the extracted user provision information synthetic | combination module 221 is output to the user terminal device 1 (S207). Accordingly, the user can know the user-provided information synthesis module 221 related to the keyword, and the designation of the user-provided information synthesis module 221 in the processing (S101) is facilitated.

  On the other hand, when the user selects the workflow search, the workflow model is displayed (S204). It is desirable for the workflow model to display the relationship between the previous and subsequent work units in a visually easy-to-understand manner with reference to the previous work list 2113 and the subsequent work list 2114 of the work unit 211.

  Then, the selection of the work unit 211 is received from the user (S205). When the selection of the work unit 211 is received, the set user-provided information synthesis module 221 is extracted with reference to the related synthesis module list 2115 of the selected work unit 211 (S206).

  Then, the extracted user provided information composition module 221 is output to the user terminal device 1 (S207). Thereby, the user can know the user provided information composition module 221 related to the selected work unit 211, and the designation of the user provided information composition module 221 in the processing (S101) becomes easy.
