  Next, the best mode for carrying out the invention will be described in detail with reference to the drawings. FIG. 1 shows a configuration of an automatic software generation apparatus 1 according to an embodiment of the present invention. FIG. 1 also shows a business system 2 that executes software created by the automatic software generation apparatus 1.

  Referring to FIG. 1, an automatic software generation apparatus 1 according to the present invention is an information processing apparatus that operates under program control, and includes a specification definition unit 12, a software generation unit 13, and a distribution unit 14 in a data processing unit 11, and a storage unit 15 holds software information 17. The storage unit 15 also stores a plurality of specification definition tables 16-1 to 16-4 and generated software 18.

  The data processing unit 11 includes a CPU, a main memory, an input device such as a keyboard, and a display device (not shown) as hardware. The storage unit 15 is a non-volatile auxiliary storage device such as a magnetic disk device and stores files.

  The specification definition means 12 is a table creation software or a spreadsheet software, and creates specification definition tables 16-1 to 16-4. As shown in FIG. 2, each of the specification definition tables 16-1 to 16-4 includes a processing content description line 111, a common parameter description line 112, an execution parameter description line 113, a line type description column 114, a process A content description column 115 is included. A broken line in the execution parameter description area indicates that the block is a combination of individual cells.

  The software generation unit 13 reads the specification definition table 16-1, generates corresponding software while sequentially scanning the cells of the table, generates software corresponding to the specification definition table 16-4 in the same manner, and The software information 17 that is predefined software including the standard function is combined, and the generated software 18 is stored in the storage unit 15.

  The distribution unit 14 distributes the generated software 18 to the software execution device 21 through the network 100 such as a LAN.

  The software execution device 21 is an information processing device such as a server, and provides services related to reference and update of the database 22 to a terminal 23 such as a personal computer under the control of distributed software. Service is performed through the network 101.

  Next, the details of the specification definition tables 16-1 to 16-4 and the generation software 18 and the schematic operation of each means of the software automatic generation apparatus 1 will be described. Each of the specification definition tables 16-1 to 16-4 is tabular document data that defines the specifications of the business system 2. As shown in FIG. 2, the processing content description line 111, the common parameter description line 112, and the execution are executed. The parameter description line 113 is divided into three types of lines and arranged in this order.

  In the horizontal direction, the row type description column 114 and the processing content description column 115 are divided into two types of columns, which are arranged in this order.

  In the line type description column 114, a keyword for identifying the line type is automatically described by the specification defining means 12. That is, “action” indicating the processing content description line 111, “common” indicating the common parameter description line 112, and “pattern” indicating the execution parameter description line 113 are described.

  The specification defining unit 12 describes the following contents in the processing content description column 115 in accordance with the instruction input. The processing content description line 111 describes a keyword indicating the processing content or the name of software (module) corresponding to any of the other specification definition tables 16-2 to 16-4.

  In the common parameter description line 112, parameters are described as necessary for each process. In the example of FIG. 2, “layer”, “sheet”, “event”, and “var1” that are variable names are described as parameters for the processes “case” and “set” that take the variable names as parameters. For processes “VCMAP” and “C” that take a column as a parameter, character strings “HHHH” and “EEEE” are described as parameters.

  Some variables are automatically assigned values by the system. For example, “layer” is the name of the table currently being processed, “sheet” is the name of the currently displayed screen, and “event” is the user name. The name of the operation performed by is automatically substituted.

  The meaning of the contents described in the execution parameter description line 113 changes as follows depending on the contents of the processing contents description line 111 in the same column.

  When the keyword “case” indicating a conditional branch is entered in the execution parameter description line 113, a condition value that determines whether or not the line is executed is described. When a keyword other than the keyword “case” is entered in the execution parameter description line 113, whether or not to execute the processing content indicated by the keyword and the parameters for execution are described.

  The software generation unit 13 reads the specification definition table 16-1 and generates the generation software 18 while scanning the cells in the table in order. In the generation, first, the processing content description line 111, the common parameter description line 112, and the execution parameter description line 113 are identified from the contents (keywords) of the line type description column 114.

  Next, the software generation unit 13 adds processing instructions to the generation software 18 while scanning all the cells in the processing content description column 115 of the execution parameter description row 113. Scanning starts from the scanning start position 116, which is the upper left corner of the execution parameter area. From the left to the right, and after reaching the right end, the scanning is performed in the order of the left end of the next line in the execution parameter area. Continue to the bottom of line 113.

  At this time, a blank cell is ignored if it is not a cell combined with a cell having a parameter value and the parameter value is a null cell (for example, cell 117), and proceeds to the next cell. The processing instruction added in each cell is determined by the content of the processing content description line 111 in the same column as that cell. When the content of the processing content description line 111 is a keyword “case” indicating a conditional branch, a control structure indicating a conditional branch is added as a processing instruction. For example, in the case of C language, an “if” sentence is added. At this time, the control structure in the upper row may be continued, so that the conditional branch control structure is appropriately completed.

  If the content of the processing content description line 111 is a keyword indicating a predefined processing command, a processing command corresponding to the keyword is added to the generation software 18. When the content of the processing content description line 111 is not a processing command corresponding to a predefined keyword, a function (callable) for calling a software module generated from another specification definition table is added to the generation software 18.

  Thereafter, the software generation unit 13 reads the specification definition table 16-2, generates the software in the same manner, and adds to or combines with the generation software 18. After processing up to the specification definition table 16-4, finally, the software included in the software information 17 is added to the generation software 18, and the generation of the software is completed.

  The software information 17 includes software for executing a predefined process such as a standard function, and also includes a function such as “calltable” defined in advance by a user of the software automatic generation apparatus.

  The generated software 18 is software generated by the software generating unit 13, and operates as a system when receiving a download request and distributing the distribution unit 14 to the software execution device 21.

Next, the operation of the best mode for carrying out the present invention will be described using specific examples.
First, a description will be given of a first embodiment in which the content of the created specification definition table is as shown in FIG. FIG. 3 is a flowchart showing the operation of the software generation means 13.

  The specification definition means 12 is used to input the screen transition table of the specification information, and the specification definition table 16-1 of FIG. 2 is created. Here, the first column of the specification definition table 16-1 in FIG. 2 is based on the premise that the table being processed is V (screen processing). Next, other specification definition tables are created in the same manner.

  Here, each file of the specification definition tables 16-1 to 16-4 corresponds to a table size (row identification maximum value and column identification maximum value) and a grid position (row identification and column identification). The content is set to a valid value (such as a character string) or null. In addition, information related to the combination of the cells (identification of the positions of a plurality of cells constituting the block) is also set.

  The operation of the first embodiment will be described in detail below with reference to FIG. When the software generation means 13 is started, first, as initialization processing, each file in the specification definition tables 16-1 to 16-4 is made readable, and the area for the generated software 18 is initialized and writable. (Step 201).

  Next, a value indicating the scanning start position 116 is set in the variable “current grid” (step 202). Next, a processing instruction for starting processing is written in the generation software 18. For example, in the case of generating C language, it is a function definition declaration or the like (step 203).

  Next, 0 is set to the variable “final branch level” indicating the number of stages of the control structure of the conditional branch up to the previous line (step 204). Next, in order to scan all the lines included in the execution parameter description line 113, the process up to step 221 is repeated while moving the variable “current grid” downward line by line (step 205).

  Next, 0 is set to the variable “branch level” indicating the number of stages of the control structure of the conditional branch in the row (step 206). Next, in order to scan all the columns included in the processing content description column 115, the processing up to step 220 is repeated while moving the variable “current grid” to the right by one column. At the end of the repetition, the column position of the variable “current cell” is returned to the original position (step 207).

  Next, the contents of the cell pointed by “current cell” are referred to. If the cell is blank (the cell value is null), the process proceeds to step 216 (step 208).

  Next, the processing contents are branched. Therefore, the processing content written in the processing content description line 111 in the same column as the “current cell” is referred to, and the process branches in each of the following cases.

  If the referred keyword is the character string “case” (step 209), in order to complete the control structure of the conditional branch that is being written to the generation software 18, the number of times is (the final branch level−the branch level). The branch end processing instruction is written in the generation software 18. The branch end processing instruction is, for example, “return;}” when generating C language (step 210).

  Next, the control structure instruction for the conditional branch is written into the generation software 18. At this time, the determination condition is generated using the contents of the “current cell” and the content of the common parameter description line 112 in the same column as the “current cell”. For example, when the C language is generated, “if (“ + content of common parameter description line 112 + “==” + content of “current cell” + “) {” is obtained (step 211). Here, “+” indicates a combination of character strings.

  Next, 1 is added to the variable “branch level” indicating the number of stages of the control structure of the conditional branch (step 212). Next, the contents of the variable “branch level” are substituted into the variable “final branch level” so that the control structure of the conditional branch can be completed in the next line and thereafter (step 213).

  If the referenced keyword is one of the defined keywords (step 209), a processing instruction corresponding to the keyword is written in the generation software 18 (step 214). Here, the predefined keyword is a name indicating an instruction prepared in advance as the software automatic generation apparatus 1, and a processing instruction corresponding to the keyword is determined in advance. As an example of a predefined keyword, “set” indicating assignment to a variable is prepared.

  If the referenced keyword is not a defined keyword (step 209), it is a case where a module generated by another specification definition table is called, and a processing instruction for calling a module generated by another specification definition table is generated. Write to software 18.

  At this time, a processing instruction is generated so that the content of the processing content description line 111, the content of the common parameter description line 112, and the content of “current grid” can be transmitted to the call destination. For example, when generating the C language, “calltable (“ + contents of the processing content description line 111 + “,” + contents of the common parameter description line 112 + “,” + contents of “current cell” + “);” (Step 215).

  If the cell is blank in step 208, if the cell is combined with the cell in the previous row (step 216), the cell is written in the processing content description line 111 in the same column as the “current cell”. With reference to the processing content, if the keyword is the character string “case” (step 217), 1 is added to the variable “branch level” indicating the number of stages in the control structure of the conditional branch (step 218).

  If the processing content description is not “case” in step 217, the execution parameter value is set as the execution parameter value of the binding source cell, and the process proceeds to step 209 (step 219). In step 216, if the cell is not a combined cell, do nothing (ignore) and proceed to the next cell.

  If the “current grid” is not the last column of the row being processed, the process proceeds to step 207, and if it is the last column, the process proceeds to step 221 (step 220). If the “current grid” is not the last line, the process proceeds to step 205, and if it is the last line, the process proceeds to step 222 (step 221).

  Next, in order to complete the control structure of the conditional branch that is being written to the generation software 18, a branch end processing instruction is written in the generation software 18 as many times as (final branch level−branch level) (step 222). ).

  Next, a processing instruction for finishing the processing is written in the generation software 18 (step 223). If all the specification definition tables have not been processed (step 224), the process proceeds to step 202, the next specification definition table 16-2 is processed, and if all the specification definition tables are processed (step 224), the process proceeds to post-processing. As post-processing, processing for enabling the software execution device 21 to read the generated software 18 is performed. For example, standard function software included in the software information 17 is added to the generated software 18 (step 225).

  This completes the operation of the first embodiment of the present invention.

  When a specification definition table having a form close to a screen transition table is created as in this embodiment, software for a business system is generated.

  Next, a second embodiment of the present invention will be described. As the specification information, a state transition table and a data correspondence table are created. An example of creating a specification definition table from these and generating a program corresponding to the specification definition table will be described.

  First, when the state transition table receives the access request (REQ) in the “initial” state, the user attribute is acquired, and when the response (REPLY) is received in the “acquire screen” state, the acquired user attribute (gender and age) is acquired. It is described that the product information group corresponding to the layer is provided and the purchase screen (PUR-REQ) is received in the “provision screen” state, and the application screen is transmitted and transitions to the “application screen” state. .

  Before providing the product information group here, it is necessary to determine the group (group) number according to the gender and age group of the user, the data correspondence table is the user attribute (gender and age group) data and "provided product The correspondence of “group designation information of information group” data is shown.

  FIG. 6 shows a specification definition table created by the specification definition means 12 by inputting the state transition table as it is. In the first column, the processing content description is “case”, the common parameter is “layer” (table being processed), and the execution parameter is “S” (higher state transition management layer).

  In the second column, the processing content description is “case”, the common parameter is “sheet”, and each state value of the state transition table is set in each row of the execution parameter. In the third column, the processing content description is “case”, the common parameter is “event”, and each transition condition of the state transition table is set in each row of the execution parameter. In the eighth column, the processing content description is “chsheet” (standard function name to update and display the screen), the common parameter is “sheet” (screen section variable), and the state value (new) that transitions to each line of the execution parameter Set the status value. Here, the state value is a text value, but this may be a number.

  The first line of the execution parameter in FIG. 6 displays the acquisition screen with the first access request (instructing the chsheet function to display the income screen). The acquisition screen includes two input fields for “sex input value” and “age input value” and a “response” button. The character strings entered in the input field when the “response” button is pressed are automatically entered in the “sex input value” and “age input value”, respectively.

The second line of the execution parameter in FIG. 6 copies the input values to the variables of sex and age when receiving a response. Call the KETTEI table. (The system sets the table name “KETTEI” to the variable layer, and scans all the tables again, thereby calling the KETTEI table.)
According to the KETTEI table of FIG. 8, grp is determined from set and age and set. Returning to the table of “S” in FIG. 6, set grp to the variable “product display value”. Next, a “provision screen” is displayed (instructed to the chsheet function). The value of the variable “product display value” is automatically displayed in the product display column when the “providing screen” is displayed.

  The software generation unit 13 generates software in the same manner as in the first embodiment. FIG. 7 shows the generation software 18 generated from the specification definition table of FIG.

  Here, the specification definition table of FIG. 8 is created from the data correspondence table. The attribute data contents of the data correspondence table are embedded in the third and fourth columns of the specification definition table of FIG. That is, the processing content description in the third column is “case”, the common variable is sex, and “1” (male) and “0” (female) are entered in each block of the execution parameter. The processing content description in the fourth column is “case”, the common variable is “age”, and each block corresponding to “'1” (male) ”and“ “0” (female) ”in the execution parameter area has an age. Layers “˜20”, “20-40”, “40˜” are set.
