The front transaction Search is called. That is, the image data includes the data for displaying the screen shown in FIG. 8 and calling the front transaction.

The screen transition definition storage unit 22 defines the order in which screens transition. For example, a screen to be changed is defined according to a response to a front transaction called by each screen. FIG. 3 shows an example of the contents stored in the screen transition definition storage unit 22. 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 its processing result 222b. The next screen 223 further includes a screen 223a and its file name 223b.

In the example shown here, the following is defined. That is, the screen 221a (the search input screen 10)
0) is displayed, when an operation corresponding to the input action 221b (click of the search button 120 on the screen) is received from the user, the front transaction 2
22a (Search) is called. The screen 223a indicates to which screen a transition is made according to the result 222b of executing the front transaction. The file name 223b is a file name of the screen 223a.

The screen control section 210 controls a screen displayed on the terminal 10. For example, the screen control unit 210 acquires the screen data stored in the screen data storage unit 21 and outputs the screen data to the terminal 10. Also, the screen control unit 210
Data input to an input area (for example, a store code input area 110) of the display screen displayed on the terminal 10 is received and stored in the data store 220. further,
The 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.

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 the screen defined in the screen transition definition storage unit 22 according to the returned value.

The data store definition storage unit 23 defines the data format of each data stored in the data store 220. That is, as shown in FIG. 4, for example, the data item of the data store definition includes an input / output item 231 and a data type 2
32, a Japanese name 233, an item attribute 234, and a use screen 235 including the item. The input / output item 231 is a name of an input / output area included in the display screen. The input / output item 231 corresponds to the front end system 20.
Are named so that they can be uniquely identified. The data type 232 indicates the type of data input / output to 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 the input / output item 231. The use screen 235 indicates a file name of a screen including the input / output item 231.

The data store 220 is provided for each display screen.
The data input / output on each screen is temporarily stored. 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. Further, when storing the data, the data store 220 refers to the data store definition storage unit 23, checks the data with the content designated by the item attribute 234, performs format conversion, and performs attribute conversion. As a result, the attribute of the data is converted into the specified format, so that it is easy to handle the data when performing the subsequent processing.

The transaction conversion definition storage unit 24
Stores the conversion definition from the front transaction to the transaction of the back-end system. 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 processing request to one of the back-end systems 30. For example, when it is necessary to perform processing in a plurality of back-end systems 30 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 cases where each transaction is executed sequentially (serial) (242a) and cases where each transaction is executed in parallel (simultaneous execution or parallel) (242b).

The transaction conversion unit 230 refers to the transaction conversion definition storage unit 24 and converts a front transaction into a back-end transaction. Further, the transaction conversion unit 230 instructs the data conversion unit 240 to generate a transaction.

As shown in FIG. 6, the data conversion definition storage unit 25 stores an up message and a down message used in a back-end transaction in association with each other. Specifically, as the data conversion definition, a back-end transaction 251, an upstream message 252, a downstream message 253
Are stored in association with each other.

The format of each message is stored in the message definition storage unit 26. As shown in FIG. 7, examples of the message definition include a message name 261, a number of digits 262, a field name 263 in the message, and an input / output item 2 on the display screen.
64 are stored in association with each other. The input / output item 264
Corresponds to the input / output item 231.

The data converter 240 generates and decomposes a telegram. For example, the data conversion unit 240 receives a back-end transaction generation instruction from the transaction conversion unit 230, and generates a necessary uplink message. The generated messages are output to the corresponding connectors 250, respectively.

The generation of an upstream telegram is specifically performed as follows. The data conversion unit 240 refers to the data conversion definition storage unit 25 and
1 is acquired. Further, the format of the message is acquired from the message definition storage unit 26. Then, the data conversion unit 240 outputs the input / output item 264
Is acquired from the data store 220 to generate an upstream telegram.

The data conversion unit 240 is connected to the connector 2
The down message is received from 50, and the data is extracted from the received down message with reference to the message definition storage unit 26.
Each data extracted by the data conversion unit 240 is stored in the data store 220 at the position indicated by the input / output item 264.

The connector 250 sends and receives messages to and from the back-end system 30. One connector 250 exists for one back-end system 30.

Next, in the present system having the above-described configuration, the processing procedure when the screen transitions will be described with reference to the screen transition definition (transition from the search input screen to the shop name input screen or the search error screen) shown in FIG. explain. FIG. 9 shows a flowchart of the processing procedure.

The screen control unit 210 controls the screen data storage unit 2
1 to obtain screen data of the search input screen 100 and output 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 into 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).

Since the input action when the search button 120 is pressed is “search”, the screen control unit 210
A front transaction Search is called with reference to the screen transition definition storage unit 22 (S125). The transaction conversion unit 230 refers to the transaction conversion definition storage unit 24 and
The transaction corresponding to "ear" is instructed to the data conversion unit 240 (S130). Data converter 240
Refers to the data conversion definition storage unit 25 and determines the type of message corresponding to the instructed transaction.
Here, since the upstream message is the message 1, the data conversion unit 240 converts the message format into the message definition storage unit 2
From 6. The data conversion unit 240 obtains necessary data from the data store 220, generates a message 1, and transfers the message 1 to the connector 250. The connector 250 transmits a message to the back-end system 30 (S140).

The back-end system 30 returns a result (return value and data) of executing a predetermined process (here, search).

When the search result is received via the connector 250, the data conversion unit 240 analyzes the message and stores data to be stored in the data store 220 when there is data to be stored (S150). The screen control unit 210 determines a screen to be transitioned based on the return value and the screen transition definition. That is, when the return value is 2, the display transits 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, S19)
0).

Thus, the front end system 20
Can execute a business process request from a 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, in order to change the screen layout, etc.,
Even if screen data is updated, there is no need to change business process logic. In other words, upon receiving input from the user,
Business processes can be separated from each other, and each can be independently modified or changed. As a result, expandability and maintainability of the system are improved.

Next, in the description of the above-described embodiment, the definition information stored in each storage unit is described in the form of a table in the drawing. However, when implemented in the present embodiment, XML
(Extensible Markup Langua
ge) format. Hereinafter, a conversion device having this definition format will be described.

The definition format conversion device 50 receives, as an input, definition information described in a spreadsheet format in a table from the definition information storage unit 60 in spreadsheet format,
The data is converted into the L format and output to the XML format definition information storage unit 70. FIG. 10 shows the configuration diagram.

The definition conversion device 50 includes a plurality of definition conversion units 5
1 and a selection unit 52 for selecting the definition conversion unit 51. Each definition conversion unit 51 corresponds to each definition information.

The definition format converter 50 is constituted by a computer system. Each configuration or each function described below is realized, for example, by executing a computer program.

Definition information storage section 6 in spreadsheet format
0 stores definition information in the form of a table shown in FIGS. 3 to 7 created by a spreadsheet. The definition format conversion device 50 receives each spreadsheet as an 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
The spreadsheet is read and converted 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 to convert the spreadsheet into XML format. The definition information in XML format is
It is stored in the XML format definition information storage unit 70.

Thus, the definition information created by a general spreadsheet can be converted into another expression format.

Although the spreadsheet format has been converted to the XML format here, it may be converted to another format.

For example, 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)
Can be easily implemented without programming if it is created as definition information in a spreadsheet format.
