Description

Technical Field

[0001] The present invention relates to an update technology for business systems.

Background Art

[0002] In the development of a business system that performs a predetermined business, the requirements of the business system are defined, and the components such as hardware and software are designed to meet the requirements. Conventionally, the definition of requirements and the design of components have been performed for each user. Therefore, even for similar requirements, it has been necessary to develop business systems individually.

[0003] By designing and developing the components of a business system in units of parts, it is possible to easily construct business systems with similar requirements, and thus it is expected to reduce the development cost. In addition, by reusing the components of past business systems, it is possible to develop a new business system quickly and at low cost.

[0004] As a technology related to the development of a new business system, the technology described in Patent Document 1 is known. Patent Document 1 describes a system analysis apparatus "including a system component decomposition unit that decomposes system design information into system functional components, a system comparison unit that detects similar system detection results and similar function search results, a component performance analysis unit that obtains system component performance information associated with performance information, and a performance bottleneck detection unit that detects system functional components that become performance bottlenecks from the similar system detection results and the system component performance information".

[0011] The embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not to be construed as being limited to the embodiments described below. It will be readily apparent to those skilled in the art that the specific configuration can be modified without departing from the spirit or intent of the present invention.

[0012] In the configuration of the invention described below, the same or similar configurations or functions are denoted by the same reference numerals, and redundant descriptions are omitted.

[0013] In this specification and the like, notations such as "first", "second", "third", etc. are attached to identify components, and do not necessarily limit numbers or order.

Example

[0014] FIG. 1 is a diagram showing a configuration example of the system of Example 1. FIG. 2 is a diagram showing a configuration example of the computer constituting the update support system of Example 1.

[0015] The system of Example 1 is composed of a user terminal 100, a construction system 101, a base 102, a construction code management system 103, and an update support system 104. The user terminal 100, the construction system 101, the base 102, the construction code management system 103, and the update support system 104 are connected to each other via a network 105. The network 105 is, for example, a WAN (Wide Area Network) and a LAN (Local Area Network), etc. The connection method of the network 105 may be either wired or wireless.

[0016] The user terminal 100 is a terminal operated by a user who operates the business system 110. The user is, for example, an automobile company, a food company, a transportation company, etc.

[0017] The construction system 101 is a system managed by a developer who constructs, manages, etc. the business system 110.

[0018] Infrastructure 102 provides an environment for building business systems 110. Infrastructure 102 includes computers, network switches, and storage systems, etc. Infrastructure 102 is capable of building one or more business systems 110. Infrastructure 102 may be either on-premises or cloud-based. Users can use on-premises or cloud-based Infrastructure 102 as needed. They can also use on-premises and cloud-based Infrastructure 102 in combination.

[0019] Business system 110 is a system that performs various tasks such as quality control, manufacturing control, and inventory control. The present invention is not limited to the content and type of tasks performed by business system 110.

[0020] The construction code management system 103 manages the construction codes for building the business system 110. In Example 1, the construction codes for individual elements of the business system 110, such as databases, networks, and functions, are managed. The construction codes include the type of element, the setting procedure for the element, and the setting parameters. The construction code management system 103 manages a group of construction codes for multiple elements that make up a single business system 110 as a single file.

[0021] The business system 110 is built, for example, by the following procedure: The construction system 101 receives a request to build the business system 110 from a user terminal 100. The request includes the requirements for the business system 110. The developer designs the construction code based on the requirements for the business system 110. The developer can also reuse the construction code of a business system 110 with similar requirements. The construction system 101 uses the construction code to build the business system 110 on the infrastructure 102 and also registers the construction code in the construction code management system 103.

[0022] The update support system 104 assists in adding / updating functions to the business system 110. The update support system 104 consists of a computer 200, for example, as shown in Figure 2. The computer 200 has a processor 201, main memory 202, secondary memory 203, and a network interface 204. Each hardware element is connected to the others via a bus. The computer 200 may also have input and output devices.

[0023] The processor 201 executes the program stored in the main memory 202. The processor 201 functions as a functional unit (module) by executing processing according to the program. In the following explanation, when the processing is described with the functional unit as the subject, it indicates that the processor 201 is executing the program that realizes the functional unit.

[0024] The main memory 202 is a memory unit that stores the program executed by the processor 201 and the information used by the program. The main memory 202 also includes a work area that the program uses temporarily.

[0025] The secondary storage device 203 is an HDD (Hard Disk Drive) or SSD (Solid State Drive), etc., and permanently stores a large amount of data. Programs and information stored in the main memory 202 may also be stored in the secondary storage device 203. In this case, the processor 201 reads the programs and information from the secondary storage device 203 and loads them into the main memory 202. The network interface 204 communicates with external devices via the network.

[0026] The update support system 104 includes a configuration management unit 120 and an evaluation unit 121, and also maintains a requirements management DB 130 and a configuration management DB 131.

[0027] Requirements Management DB130 is a database for managing the requirements of business system 110. Configuration Management DB131 is a database for managing the configuration of business system 110.

[0028] The configuration management unit 120 manages the configuration of the business system 110. The evaluation unit 121 verifies the effects of adding / updating functions to the business system 110.

[0029] Furthermore, the functional units of the update support system 104 may be combined into a single functional unit, or a single functional unit may be divided into multiple functional units for each function. Additionally, the update support system 104 and the construction code management system 103 may be treated as a single system.

[0030] Figure 3 shows an example of the data structure of the requirements management DB130 in Example 1.

[0031] The requirements management DB130 stores, for example, a table 300 as shown in Figure 3. Table 300 stores entries that include a business system ID 301, user ID 302, infrastructure ID 303, industry 304, business category 305, link 306, and function 307. There is one entry for each business system 110. Note that the fields included in an entry are not limited to those described above.

[0032] Business system ID 301 is a field that stores the identification information of business system 110. User ID 302 is a field that stores the identification information of the user who operates business system 110. Infrastructure ID 303 is a field that stores the identification information of infrastructure 102 on which business system 110 is built.

[0033] Industry 304 is a field that stores the user's industry. Business Category 305 is a field that stores the type of business performed by the business system 110.

[0034] Link 306 is a field that stores a link (e.g., a URL) for accessing a set of codes (files) managed by the construction code management system 103. Function 307 is a field that stores information about the functions of the business system 110.

[0035] Note that the information stored in the requirements management DB130 is not limited to a table format. It may also be in data formats such as CSV or XML.

[0036] Figures 4A, 4B, and 4C show an example of the data structure of the configuration management DB131 in Example 1.

[0037] The configuration management DB131 stores table 400 shown in Figure 4A, table 410 shown in Figure 4B, and table 420 shown in Figure 4C.

[0038] Table 400, shown in Figure 4A, contains information for managing the elements of business system 110. Table 400 includes business system ID 401, element 402, evaluation list 403, and usage record list 404. There is one entry for each business system 110. Note that the fields included in the entry are not limited to those described above.

[0039] Business system ID 401 is the same field as business system ID 301. Element 402 is a field that stores an overview of the elements that make up business system 110.

[0040] Evaluation list 403 is a field that stores identification information for data (entries in table 410) that stores the results of verifying the effectiveness of applying the added / updated functions to other business systems 110.

[0041] Usage record list 404 is a field that stores identification information for data (entries in table 420) that stores the usage record of added / updated functions in other business systems 110.

[0042] Table 410, shown in Figure 4B, contains information for managing the results of effectiveness verification. Table 410 stores entries that include evaluation ID 411, business system ID 412, element 413, and result 414. There is one entry for each effectiveness verification result. Note that the fields included in the entries are not limited to those described above.

[0043] Evaluation ID 411 is a field that stores identification information for the effectiveness verification result. Business system ID 412 is a field that stores identification information for the business system 110 on which the effectiveness verification was performed. Element 413 is a field that stores information for the verified element (function). Result 414 is a field that stores the effectiveness verification result.

[0044] In Example 1, various effects are verified depending on the tasks performed by the business system 110 and the functions to be verified. For example, throughput is measured, profit amounts are calculated, and CO2 reduction amounts are calculated.

[0045] Table 420, shown in Figure 4C, contains information for managing usage records. Table 420 stores entries that include a usage record ID 421, a business system ID 422, and a usage element 423. There is one entry for each usage record. Note that the fields included in an entry are not limited to those described above.

[0046] Usage record ID 421 is a field that stores identification information for usage records. Business system ID 422 is a field that stores identification information for business system 110 on which functions were added / updated based on the results of effectiveness verification. Usage element 423 is a field that stores information about the added / updated elements (functions).

[0047] Tables 400, 410, and 420 may be managed as a single table. Furthermore, the information stored in the configuration management DB131 is not limited to a table format; it may also be in data formats such as CSV or XML.

[0048] Figure 5 is a flowchart illustrating an example of the process performed by the update support system 104 in Example 1. Figure 6 is a diagram showing an example of the construction code for Example 1.

[0049] The update support system 104 receives input of information (business system information) for the newly constructed business system 110 from the construction system 101 (step S101).

[0050] The business system information includes identification information for business system 110, user identification information, industry, business category, identification information for the infrastructure 102 on which business system 110 was generated, a link to the file containing the construction code for business system 110, and information regarding its functions.

[0051] The update support system 104 updates the requirements management DB 130 based on the business system information (step S102).

[0052] Specifically, the configuration management unit 120 of the update support system 104 adds an entry to the requirements management DB 130 and sets values ​​for each field of the added entry based on the business system information.

[0053] Note that the business system information does not necessarily have to include information about functions. In this case, the configuration management unit 120 acquires the code group (file) managed by the construction code management system 103 and identifies the function by analyzing the code group. The construction code is, for example, data like that shown in Figure 6.

[0054] The update support system 104 performs configuration analysis processing and updates the configuration management DB 131 based on the analysis results (step S103). Specifically, the following processes are performed.

[0055] (S103-1) The configuration management unit 120 acquires the code set managed by the construction code management system 103 and identifies the set of elements that constitute the business system 110 by analyzing the code set.

[0056] (S103-2) The configuration management unit 120 adds an entry to table 400 and sets the identification information of business system 110 in business system ID 401. The configuration management unit 120 sets the information of the specified group of elements in element 402 of the added entry. At this point, evaluation list 403 and usage record list 404 are blank.

[0057] Figure 7 is a flowchart illustrating an example of the process performed by the update support system 104 in Example 1. Figure 8 is a diagram showing an example of the screen displayed on the user terminal 100 in Example 1.

[0058] The update support system 104 receives a function addition notification from the construction system 101, which includes information about functions added / updated to the business system 110 (step S201). The function addition notification includes identification information for the business system 110 and information about the added / updated functions (function information). The function information includes, for example, the name of the application that implements the function. Hereinafter, the business system 110 with added / updated functions will be referred to as the updated business system 110. The added / updated functions will also be referred to as new functions.

[0059] The feature addition notification may be sent when a function is added to or updated in the update business system 110, or it may be sent after verifying the effectiveness of the updated business system 110 with the added or updated function. For example, a feature addition notification could be sent when an improvement in throughput is confirmed. This would allow the insights gained from the update business system 110 to be used when considering updates to other business systems 110.

[0060] The update support system 104 identifies a business system 110 similar to the update business system 110 (step S202). Specifically, the following processes are executed.

[0061] (S202-1) The evaluation unit 121 refers to the table 300 stored in the requirements management DB 130 and searches for an entry corresponding to the updated business system 110 based on the identification information of the business system 110 included in the function addition notification. Hereinafter, the searched entry will be referred to as the target entry.

[0062] (S202-2) The evaluation unit 121 selects one entry from table 300. Hereafter, the selected entry will be referred to as the comparison entry. The business system 110 corresponding to the comparison entry will be referred to as the comparison business system 110. Note that the target entry is not included in the selection.

[0063] (S202-3) The evaluation unit 121 determines whether the business category 305 values ​​of the target entry and the comparison entry match. If the business category 305 values ​​of the target entry and the comparison entry do not match, the evaluation unit 121 proceeds to S202-8.

[0064] Even if the industries are different, if the business operations are the same, it is expected that the introduction of new functions will yield the same effects as the updated business system 110. Therefore, the evaluation unit 121 performs the following processing on business systems 110 whose operations are the same.

[0065] (S202-4) If the values ​​of business category 305 for the target entry and the comparison entry match, the evaluation unit 121 refers to table 400 in the configuration management DB 131 and searches for entries corresponding to the update business system 110 and the comparison business system 110.

[0066] (S202-5) The evaluation unit 121 counts the number of duplicate elements based on the elements 402 of the searched entry and calculates the similarity score based on that number.

[0067] The method for calculating similarity is not limited to those described above. For example, the evaluation unit 121 may obtain a group of construction codes from the construction code management system 103 based on the link 306 between the target entry and the comparison entry, compare the groups of construction codes, and calculate the similarity. Alternatively, the evaluation unit 121 may calculate the number of overlapping functions based on the functions 307 of the target entry and the comparison entry, and calculate the similarity based on that number. Furthermore, the evaluation unit 121 may consider the similarity of the data structures handled by the two business systems 110. In addition, the methods described above may be combined.

[0068] (S202-6) The evaluation unit 121 determines whether the similarity is greater than or equal to the threshold. If the similarity is less than or equal to the threshold, the evaluation unit 121 proceeds to S202-8.

[0069] (S202-7) If the similarity is greater than the threshold, the evaluation unit 121 determines that the update system 110 and the comparison system 110 are similar and registers the identification information of the comparison system 110 in the list. Hereinafter, the comparison system 110 registered in the list will be referred to as the similar system 110.

[0070] (S202-8) The evaluation unit 121 determines whether processing has been completed for all entries in table 300. If processing has not been completed for all entries in table 300, the evaluation unit 121 returns to S202-2. If processing has been completed for all entries in table 300, the evaluation unit 121 terminates the processing in step S202.

[0071] The update system 110 starts loop processing of similar business systems 110 (step S203). Specifically, the evaluation unit 121 selects one similar business system 110 from the list.

[0072] The update support system 104 determines whether or not it is necessary to verify the effectiveness of the new function in relation to the similar business system 110 (step S204).

[0073] Specifically, the evaluation unit 121 refers to table 400 of the configuration management DB 131 and searches for an entry corresponding to the similar business system 110. Based on the link 306 of the searched entry, the evaluation unit 121 obtains a set of construction codes from the construction code management system 103. By analyzing the set of construction codes, the evaluation unit 121 determines whether the similar business system 110 has implemented the same functionality as the new functionality. For example, if the similar business system 110 contains elements with the same name and version as the application that implements the new functionality, it is determined that the similar business system 110 has implemented the same functionality as the new functionality. If the similar business system 110 does not have implemented the same functionality as the new functionality, the evaluation unit 121 determines that it is necessary to verify the effectiveness of the new functionality for the similar business system 110.

[0074] Furthermore, applications that are different but have the same functionality may be considered to have the same functionality implemented.

[0075] If it is not necessary to verify the effectiveness of the new function against the similar business system 110, the update support system 104 proceeds to step S209.

[0076] If it is necessary to verify the effectiveness of the new function against the similar business system 110, the update support system 104 generates a set of evaluation codes (step S205). Specifically, the following processes are executed.

[0077] (S205-1) The evaluation unit 121 obtains the respective construction code sets for the update business system 110 and the similar business system 110 from the construction code management system 103.

[0078] (S205-2) The evaluation unit 121 identifies the construction code for the new function by analyzing the construction code group of the update business system 110 based on the function addition notification.

[0079] (S205-3) The evaluation unit 121 generates construction code for the new function by modifying, adding, and deleting parameters of the construction code for the new function based on the construction code group of the similar business system 110. At this time, the evaluation unit 121 modifies, adds, and deletes a part of the construction code group of the similar business system 110 in order to adjust the interfaces and protocols necessary for the operation of the new function. For example, the network address of the virtual machine on which the application runs is changed. The evaluation unit 121 outputs the construction code for the new function and the construction code group of the similar business system 110 as an evaluation code group.

[0080] The update support system 104 performs an effectiveness verification process using the evaluation code set (step S206).

[0081] Specifically, the evaluation unit 121 constructs an evaluation business system 110 using a set of evaluation codes and measures the behavior of the evaluation business system 110. The infrastructure 102 on which the business system 110 is constructed may be selected randomly or based on arbitrary rules. Alternatively, a verification infrastructure 102 may be prepared in advance.

[0082] For example, if the new function is a search function, the evaluation unit 121 inputs a search query into the evaluation business system 110 and observes the response to the search query (search speed, search results, etc.).

[0083] The update support system 104 updates the configuration management DB 131 based on the results of the effectiveness verification process (step S207). Specifically, the following processes are executed.

[0084] (S207-1) The evaluation unit 121 adds an entry to table 410 of the configuration management DB 131 and sets identification information in the evaluation ID 411 of the added entry. The evaluation unit 121 sets the identification information of the similar business system 110 in the business system ID 412 of the added entry. The evaluation unit 121 sets elements related to the new function in element 413 based on the evaluation code group for the new function. The evaluation unit 121 sets the result of the effectiveness verification process in the result 414 of the added entry.

[0085] (S207-2) The evaluation unit 121 refers to table 400 of the configuration management DB 131 and searches for an entry corresponding to the update business system 110. The evaluation unit 121 sets the identification information set as evaluation ID 411 in S207-1 in the evaluation list 403 of the searched entry.

[0086] The update support system 104 generates display information to present the results of the effectiveness verification process to the similar business system 110 (step S208), and then proceeds to step S209. The update support system 104 may present the information directly to the user terminal 100, or it may present the information to the user terminal 100 via the construction system 101. The display information may also include the number of identification information set in the usage record list 404 of table 400.

[0087] In step S209, the update support system 104 determines whether processing has been completed for all similar business systems 110 registered in the list (step S209).

[0088] If processing is not complete for all similar business systems 110 registered in the list, the update support system 104 returns to step S203. If processing is complete for all similar business systems 110 registered in the list, the update support system 104 terminates processing.

[0089] The user terminal 100 displays a screen 800, for example, as shown in Figure 8. The screen 800 includes a display field 801, a display field 802, a details button 803, a display field 804, an execute button 805, and an inquiry button 806.

[0090] Display field 801 displays information about the function and information about adding / updating the function. Display field 802 displays an overview of the effectiveness verification results. The details button 803 is an operation button to display details of the effectiveness verification results. When the details button 803 is operated, for example, a graph of throughput before and after the introduction of the new function, the increase in profit, the amount of cost reduction, etc., will be displayed. Display field 804 displays the number of similar business systems 110 to which the new function has been introduced (number of usage records). If there are many business systems 110 that have introduced the function, it can be inferred that the function is useful. Therefore, the number of usage records is displayed on screen 800.

[0091] The execute button 805 is an operation button used to instruct the introduction of a new function into the business system 110. When the execute button 805 is pressed, the construction system 101 obtains the construction code for the new function generated by the update support system 104 and uses this construction code to introduce the new function into the business system 110. This reduces the cost of generating the construction code for the new function. Developers can modify the construction code for the new function as needed.

[0092] The inquiry button 806 is an operation button for making inquiries regarding the introduction of a new feature. When the inquiry button 806 is operated, an inquiry regarding the introduction of the new feature is made between the user and the developer. Based on the response to the inquiry, the user may operate the execute button 805.

[0093] When the execute button 805 is pressed, the update support system 104 updates the configuration management DB 131. Specifically, the evaluation unit 121 adds an entry to table 420 and sets identification information in the usage history ID 421 of the added entry.
