BACKGROUND OF THE INVENTION
The present invention relates to a computer system that is easy to maintain.
[0002]
BACKGROUND OF THE INVENTION
A computer system that receives various operations directly from a user and performs various processes can be divided into a part related to a user interface and a business process logic related to a specific business process.
[0003]
The user interface design standard has various factors such as the impression that the appearance gives to the user, and operability. Therefore, a high degree of freedom is required for user interface design. Also, the user interface may change frequently for a variety of reasons.
[0004]
On the other hand, the business process logic does not need to be changed with the change of the user interface. Rather, it is inconvenient if the business processing logic has to be changed every time the user interface is changed.
[0005]
Therefore, an object of the present invention is to provide a computer system or the like that can independently change a user interface and a business processing logic.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention performs the following processing. That is, the first storage unit that stores screen data for displaying a screen for receiving an input operation from the user, information indicating the correspondence between the input operation that can be received by the screen and a processing request for another system. In a computer system including a second storage unit that stores data, the first storage unit is referred to, and the screen is displayed on a display device based on the screen data. When an input operation for the displayed screen is accepted, the second storage unit is referred to generate and output information for requesting the processing corresponding to the input operation.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0008]
FIG. 1 shows the overall configuration of a business processing system to which the present invention is applied. The system includes a terminal 10, a front end system 20, and a back end system 30. A plurality of terminals 10 and back-end systems 30 may be provided. The front end system 20 is connected to each terminal 10 and each back end system 30. The system can also include a plurality of front end systems 20. In that case, the contents of the data store 220 (to be described later) may be synchronized between the front-end systems 20 and the terminals 10, or the data store 220 is provided outside the front-end system 20, and each front-end system 20 The system 20 may share the data store 220.
[0009]
The terminal 10 includes an input device and a display device (not shown), displays information for the user, and accepts input thereto. The front end system 20 functions as an interface system between the terminal 10 and the back end system 30. That is, a business process request from a user is received via the terminal 10 and a business process request is output to any one or more back-end systems 30 accordingly. Further, the front end system 20 receives the business process result from each back end system 30. Each of the back-end systems 30 receives a business process request from the front-end system 20 and performs a predetermined process. The processing result is returned to the front end system 20. Further, information corresponding to the processing result is returned from the front end system 20 to the terminal 10.
[0010]
The terminal 10, the front end system 20, and the back end system 30 are all configured by a computer system. Each configuration or each function described below is realized, for example, by executing a computer program.
[0011]
FIG. 2 shows the configuration of the front-end system 20. The front-end system 20 includes a screen data storage unit 21, a screen transition definition storage unit 22, a data store definition storage unit 23, a transaction conversion definition storage unit 24, a data conversion definition storage unit 25, and a message definition storage unit 26. A screen controller 210, a data store 220, a data converter 230, and a connector 250.
[0012]
The screen data storage unit 21 stores screen data to be displayed on the display device of the terminal 10. The screen data is created in advance in, for example, an HTML (Hyper Text Markup Language) format. The screen displayed based on each screen data receives an input operation from the user, and the screen control unit 210 calls a front transaction according to the operation content.
[0013]
For example, FIG. 8 shows an example when the screen data of the search input screen 100 is displayed on the terminal 10. The search input screen 100 includes a store code input area 110 and a search button 120. When the search button 120 is pressed, the front transaction Search is called. That is, the image data includes data for displaying the screen shown in FIG. 8 and calling a front transaction.
[0014]
The screen transition definition storage unit 22 defines the order of screen transition. For example, a screen that transitions according to a response to a front transaction that each screen calls is defined. An example of the contents stored in the screen transition definition storage unit 22 is shown in FIG. Here, the input information 221, the business process 222, and the next screen 223 are associated with each other. The input information 221 further includes a screen 221a and an input action 221b. The business process 222 further includes a front transaction 222a and a processing result 222b. The next screen 223 further includes a screen 223a and its file name 223b.
[0015]
In the example shown here, the following is defined. That is, when the screen 221a (search input screen 100) is displayed and the user receives an operation corresponding to the input action 221b (click on the search button 120 on the screen), the front transaction 222a (Search) is called. Is done. A screen 223a indicates which screen is to be changed according to the result 222b of the front transaction. The file name 223b is the file name of the screen 223a.
[0016]
The screen control unit 210 controls the screen displayed on the terminal 10. For example, the screen control unit 210 acquires screen data stored in the screen data storage unit 21 and outputs the screen data to the terminal 10. Further, the screen control unit 210 accepts data input to an input area (for example, the store code input area 110) of the display screen displayed on the terminal 10 and stores the data in the data store 220. Further, data is acquired from the data store 220 and output to the terminal 10 together with the screen data for display on the display screen.
[0017]
In addition, the screen control unit 210 receives a return value indicating the processing result of the front transaction. Then, the screen control unit 210 makes a transition to a screen defined in the screen transition definition storage unit 22 according to the return value.
[0018]
The data store definition storage unit 23 defines the data format of each data stored in the data store 220. That is, the data items of the data store definition include, as shown in FIG. 4, for example, an input / output item 231, a data type 232, a Japanese name 233, an item attribute 234, and a usage screen 235 including the item. Including. The input / output item 231 is the name of the input / output area included in the display screen. The input / output item 231 is named so that it can be uniquely identified in the front-end system 20. The data type 232 indicates the type of data input / output to / from the input / output item. The Japanese name 233 is the Japanese name of the input / output item 231. The item attribute 234 indicates an attribute of data input / output to / from the input / output item 231. The usage screen 235 indicates the file name of the screen including the input / output item 231.
[0019]
The data store 220 temporarily stores data input / output on each screen for each display screen. Specifically, the data store 220 has an area for storing data input to the input area of the display screen and data to be output to the display screen for each input / output item 231. Furthermore, when storing the data, the data store 220 refers to the data store definition storage unit 23 to check, format conversion, and attribute conversion of the data with the content specified by the item attribute 234. As a result, the data attributes are converted into the designated format, so that the data can be easily handled during the subsequent processing.
[0020]
The transaction conversion definition storage unit 24 stores a conversion definition from a front transaction to a back-end system transaction. That is, the transaction conversion definition stores, for example, a front transaction 241 and a back-end transaction 242 in association with each other as shown in FIG. Each transaction 242 is a business process request for any back-end system 30. For example, when it is necessary to perform processing in a plurality of back-end systems 30 in order to execute one front transaction, a plurality of back-end transactions 242 are associated with one front transaction 241. When a plurality of back-end transactions are associated, there are a case where each transaction is executed sequentially (serially) (242a) and a case where each transaction is executed in parallel (simultaneous execution or parallel) (242b).
[0021]
The transaction conversion unit 230 refers to the transaction conversion definition storage unit 24 and converts from a front transaction to a back-end transaction. The transaction converter 230 instructs the data converter 240 to generate a transaction.
[0022]
As shown in FIG. 6, the data conversion definition storage unit 25 stores an uplink message and a downlink message used in a back-end transaction in association with each other. Specifically, the back-end transaction 251, the upstream message 252, and the downstream message 253 are stored in association with each other as the data conversion definition.
[0023]
The format of each message is stored in the message definition storage unit 26. In the example of the message definition, as shown in FIG. 7, the message name 261, the number of digits 262, the field name 263 in the message, and the input / output item 264 on the display screen are stored in association with each other. The input / output item 264 corresponds to the input / output item 231.
[0024]
The data conversion unit 240 generates and decomposes a message. For example, the data conversion unit 240 receives a back-end transaction generation instruction from the transaction conversion unit 230 and generates a necessary upstream message. Each of the generated messages is output to the corresponding connector 250.
[0025]
Specifically, the generation of the upstream message is performed as follows. The data conversion unit 240 refers to the data conversion definition storage unit 25 and acquires the upstream message 252 corresponding to the back-end transaction 251. Furthermore, the format of the message is acquired from the message definition storage unit 26. Then, the data conversion unit 240 acquires the data indicated by the input / output item 264 from the data store 220 and generates an upstream message.
[0026]
In addition, the data conversion unit 240 receives a downstream message from the connector 250, refers to the message definition storage unit 26, and extracts data from the received downstream message. Each piece of data extracted by the data conversion unit 240 is stored in the position indicated by the input / output item 264 of the data store 220.
[0027]
The connector 250 transmits and receives messages with the back-end system 30. One connector 250 exists for one back-end system 30.
[0028]
Next, in the present system having the above-described configuration, a processing procedure when the screen transitions will be described using the screen transition definition (transition from the search input screen to the store name input screen or the search error screen) shown in FIG. 3 as an example. A flowchart of the processing procedure is shown in FIG.
[0029]
The screen control unit 210 acquires the screen data of the search input screen 100 from the screen data storage unit 21 and outputs it to the terminal 10. In the terminal 10, the search input screen 100 is displayed on the display device (S110). On this screen, the user inputs the store code in the input area 110 and presses the search button 120. The screen control unit 210 takes in the data input to the input area 110 and stores it in the data store (S120).
[0030]
Since the input action when the search button 120 is pressed is “search”, the screen control unit 210 refers to the screen transition definition storage unit 22 and calls the front transaction Search (S125). The transaction conversion unit 230 refers to the transaction conversion definition storage unit 24 and instructs the data conversion unit 240 to perform a transaction corresponding to the front transaction Search (S130). The data conversion unit 240 refers to the data conversion definition storage unit 25 and determines the type of message corresponding to the received transaction. Here, since the uplink message is message 1, the data conversion unit 240 acquires the message format from the message definition storage unit 26. The data conversion unit 240 acquires necessary data from the data store 220, generates a message 1, and passes it to the connector 250. The connector 250 transmits a message to the backend system 30 (S140).
[0031]
The back-end system 30 returns a result (return value and data) of executing a predetermined process (here, search).
[0032]
When the search result is received via the connector 250, the data conversion unit 240 analyzes the message and stores the data to be stored in the data store 220 (S150). The screen control unit 210 determines a transition screen based on the return value and the screen transition definition. That is, when the return value is 2, the screen transitions to the store name input screen (S160, S170). When the return value is 1 or 0, the screen transits to the search error screen (S180, S190).
[0033]
Accordingly, the front-end system 20 can execute a business process request from the user according to each definition information. In particular, the entity of the front transaction called by the input action accepted by the screen data is determined by the transaction conversion definition. Therefore, even if the screen data is updated in order to change the screen layout or the like, there is no need to change the business process logic. That is, it is possible to separate input reception from the user and business processing, and it is possible to make corrections and changes independently of each other. As a result, the expandability and maintainability of the system are improved.
[0034]
Next, in the description of the above embodiment, the definition information stored in each storage unit has been described in the form of a table in the drawing. However, when implemented in the present embodiment, one converted into an XML (Extensible Markup Language) format is used. Hereinafter, the conversion apparatus of this definition format will be described.
[0035]
The definition format conversion apparatus 50 receives definition information described in a spreadsheet format from the spreadsheet format definition information storage unit 60 as an input, converts the definition information into an XML format, and outputs the XML format definition information storage unit 70. The configuration diagram is shown in FIG.
[0036]
The definition conversion device 50 includes a plurality of definition conversion units 51 and a selection unit 52 that selects the definition conversion unit 51. Each definition conversion unit 51 corresponds to each definition information.
[0037]
The definition format conversion apparatus 50 is configured by a computer system. Each configuration or each function described below is realized, for example, by executing a computer program.
[0038]
The spreadsheet format definition information storage unit 60 stores the definition information in the table format shown in FIGS. The definition format conversion apparatus 50 receives each spreadsheet as input. Then, the selection unit 52 determines which definition information is based on the file name of the spreadsheet. As a result of the determination, the definition conversion unit 51 corresponding to the input spreadsheet is selected. The selected definition conversion unit 51 reads the spreadsheet and converts it into the XML format based on a predetermined conversion rule. Specifically, each definition conversion unit 51 has an XML template. Then, the spreadsheet cell is read and applied to the template and converted into the XML format. The XML format definition information is stored in the XML format definition information storage unit 70.
[0039]
Thereby, the definition information created with a general spreadsheet can be converted into another expression format.
[0040]
Here, the spreadsheet format is converted to the XML format, but may be converted to another format.
[0041]
For example, if the correspondence between the input from the user and the business process (transaction conversion definition) or the correspondence between the processing result of the business process and the screen to be displayed (screen transition definition) is created as definition information in spreadsheet format, Can be easily implemented without programming.
[0042]
【The invention's effect】
