Abstract

PURPOSE:To improve the (problem analysis diagram) (PAD) generation efficiency by analyzing PAD description language and generating a PAD, when a symbol used in the PAD and a processing name described in the symbol are inputted by a document format (PAD description language). CONSTITUTION:The device is constituted of a PAD description language storage part 1, a monitor 2, a keyboard 3, a PAD converting part 4, a PAD storage part 5, and a printer 6. In such a state, when a symbol for constituting a PAD, and a processing name in its symbol are inputted by a document format, its document information is analyzed, and the PAD is generated automatically. Accordingly, it is unnecessary to plot directly the PAD on the monitor 2, and also, in the case of executing a correction, as well, it can be executed by a document format. In such a way, the time required for generating the PAD and user's labor spent therefor can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application This invention relates to specifications created in the process of developing computer software, and in particular to PAD (Proble+SAN), which expresses the processing structure of software in a diagram format.
It relates to a device for creating an lysis diagram (translated as a problem analysis diagram).

B. Prior Art When describing the specifications of software, drawings called PAD have recently come to be used as a means to express the processing structure of the software in an easy-to-understand diagram format. An example of this PAD is shown in FIG. 5. The PAD in FIG. 5 is an example of a processing procedure for software development.

In the figure, numerals 1 to 4 refer to symbols used in PAD, K1 is a symbol that represents the start or end of processing, and 2 is a symbol that represents loop processing (repetitive processing). The processing symbol that continues to the right of the symbol indicates that the process 3 is repeated until the condition written in the symbol is satisfied. 4 is a symbol that represents branch processing, and the number of folds on the right side of the symbol corresponds to the number of branches, and depending on the conditions described in the symbol,
This represents the execution of the process connected to the end of the fold.

As a method for creating such a PAD, methods using the following two types of devices are known.

■Document creation bag W (word processor) with graphic creation function,
A PAD is created using a computer equipped with graphic creation software.

■Create a PAD on your computer using PAD creation software. This PAD creation software stores symbols as shown in Figure 5 in advance as basic shapes, and has a function to display and edit symbols specified by the user on the monitor display. .

Problems to be Solved by the C0 Invention However, the above-mentioned conventional device has the following problems.

To create a PAD using the device described in (2), the process of creating a symbol as shown in Figure 5 using its graphic creation function, and then writing the process name in the created symbol. It is necessary to go through. For this reason, there was a drawback that it took a considerable amount of time and effort to create.

In the case of the device shown in ■, the symbol is registered in advance, so
Although it is possible to save the trouble of creating symbols, PAD
It is necessary to learn how to use the creation software, that is, dedicated software, and a certain amount of time and effort is spent on learning it.

Also, in both ■ and ■, when modifying (delete, move and insert) a PAD, the already created PAD is read out and displayed on the monitor display, and the PAD can be edited directly on the display screen.
It was necessary to re-edit and draw D, which was also time-consuming.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a PAD creation device that can improve the work efficiency of creating and modifying a PAD.

Means for Solving Process D1 The present invention has the following configuration to achieve the above object.

That is, the present invention provides a PAD creation device that creates a PAD that represents the processing structure of computer software in a diagram form, and provides various graphical symbols (symbols) used in the PAD and descriptions in the symbols. an input means for inputting a PAD description language in which a process name is expressed in a document format; and a PA for storing the input PAD description language.
D description language storage unit and the PAD description language are analyzed and PA
PAD converting means for creating D, and the created PAD
The invention is characterized by comprising a PAD storage means for storing the PAD, and an output means for outputting the created PAD to the outside.

80 Effects According to this invention, when the input means inputs a symbol used in PAD and a process name described in the symbol in a document format (PAD description language), the PAD conversion means analyzes the PAD description language. Create a PAD.

Also, when modifying a PAD that has been created, the PAD
The PAD description language stored in the description language storage section is read out and output to a monitor which is one of the output means. The user makes corrections in the language while looking at the monitor screen,
Update the PAD description language storage unit with the corrected PAD description language. The PAD conversion means analyzes the modified PAD description language and creates a new PAD.

Therefore, there is no need to draw or modify the PAD directly on the monitor as in the past, which saves time and effort.

The PAD generated in this manner is stored in the PAD storage section, and is outputted to the outside from the PAD output means as necessary.

F. Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram schematically showing the configuration of an embodiment of the present invention.

The PAD description language storage unit 1 is a storage unit that stores the PAD description language input by the user via the monitor 2 and keyboard 3 (the monitor 2 and the keyboard 3 correspond to input means, and the monitor 2 serves as output means). is also used)
.

In this PAD description language storage unit 1, a PAD description language for one PAD is stored as one document file. The PAD description language uses character strings (Ll
) and a string (
This is document information in which ``L2'' and ``L2'' are recorded line by line.

An example of this PAD description language is P in the 0-side diagram shown in Figure 2.
The AD description language indicates the language input when creating the PAD shown in FIG.

The rstart J in the first line is the character string Ll that represents the symbol for starting the process that is created first (Kl in Figure 5). This is the character string L2 representing.

runtil J on the second line is a character string L1 representing the loop processing symbol (2 in Figure 5), and is ".

What is written in the "..." portion is a character string L2 representing the process name. In other words, this second line "completes the specification"
This is a description of a loop process that repeats the following process until the process is executed.What is written in the next line (third line) is the description language for the process to be looped. At the beginning of that line is a ", (period)", and the number of periods represents the number of levels, and py in FIG. 5 is the "0" level and the number of levels from there. This instruction code indicates that a process with one period should be created at the next level (one level to the right in the drawing), and a process with two periods should be created at the next level (two levels to the right in the drawing).

As in the 4th and 5th lines, the simple "°..." J represents a processing symbol (3 in Figure 5).
Similarly, "..." is a character string L2 representing the process name.

"rselect" on the 6th line is the branch processing symbol (3rd
In the character string L1 representing 4) in the figure, the part "...pa" is a character string L2 representing the process name. In other words, the 6th line makes a decision on the branch process, ``Is there a missing r (PAD)?'', and what is written in the next line is the branch condition statement. In this example, it is written that if [No] is selected, that is, there is an omission, the process moves to the next line.

As shown in item 2, the PAD description language defined in this embodiment allows the character string Ll representing a symbol to have the meaning of that symbol, so that relatively simple input can be performed.

Returning to FIG. 1, reference numeral 4 is a PAD conversion unit that analyzes the PAD description language and creates a PAD, and 5 is a PA that stores the created PAD data file.
D is a PAD storage section as a storage means, 6 is a printer as an output means, and 7 is an interface.

Next, the PAD creation operation (PADAD converter operation) will be explained with reference to the flowchart of FIG.

In step Sl, it is determined whether or not the analysis of all the languages in one PAD description language file stored in the PAD description language storage unit 1 has been completed. Read the PAD description language for the line, and let L be the read PAD description language.

In step S3, a character string L1 representing a symbol and a character string L2 representing a process name are extracted from the PAD description language.

In step S4, the coordinate values of the four corners of the display area H of the extracted L2 are calculated.

The display area H is a square area that includes the character string L2, and the display screen of the monitor 2 is arranged in the X-Y coordinate system (horizontal direction is
The four corners of the display area H correspond to Y) in the vertical direction.
l values H1 to H4 (see FIG. 4(a)) are calculated.

In the processes of steps 85 to 7, the type of character string L1 is determined, and the process proceeds to processes corresponding to various character strings L1'.

That is, if the character string L1 is rstart' J, the process moves to steps 38 to 9 and the character string L1 is rstart' J.
If the character string L1 is "until J", the process moves to steps Sho~13; if the character string L1 is "rselect", the process moves to steps 314~17; if the character string L1 is not the above three characters, Step 3
The process moves to steps 18 and 19.

The processing of each character string Ll will be explained individually.

(a) If the character string L1 is rstart J, in step S8, a processing start symbol (Kl in FIG. 5) is created according to the position and size of the display area H.

That is, the processing start symbol Kl is created by generating line segment data between the coordinate values of H1→H2 and H3→H4 of the display area H, and arc data between the coordinates of H1→H3 and H2→H4 ( (See Figure 4 (b)).

In step S9, the character string L is added to the created symbol Kl.
Output the graphic data with 2 inserted to the output file. This output file becomes a PAD data file stored in the PAD drawing storage section 5 of FIG.

(b) When the character string L1 is runtil J, in step 510, a loop processing symbol (2 in FIG. 5) is created according to the position and size of the display area H.

In other words, graphic data of a square surrounding each coordinate value H1 to H4 of the display area H is created, and a tiny square 2' (see Fig. 4 (C)) is added to the right side of the square. Create the loop processing symbol as 2.

In step Sll, graphic data in which the character string L2 is inserted into 2 in the created symbol is output to an output file.

In step S12, the data of the line segment lx whose starting point is the center position coordinates of the oldest side of 2' is output to a minute square (the fourth
(See figure (C)), this is because the symbol of the next process (process to be looped) is always written on the right side of the loop processing symbol, and the line segment lx is the connecting line that connects these symbols. In the next step S13, a PAD for the processing portion to be looped is created.

In step S13, first, the read address is counted up by one (L+1→L) and the PAD description language written in the next line is read.

The read PAD description language is decomposed into character strings L1 and L2, and graphic data in which the character string L2 is inserted into the symbol indicated by the character string Ll is output to the end point position of the line segment lx.

As shown in this loop processing part, the symbol that continues on the right side of PAD is expressed by adding a "period" to the beginning in the PAD description language, so from now on, the figure for the line to which "period" is added will be expressed. create data,
Output in order.

When the analysis of the document starting with a "period" is completed, the PAD of the loop processing part is completed.

(c) When the character string L1 is rselectJ, in step S14, first, the number of conditional statements written in the line following rselectJ, that is, the number of [...] is counted. This means that the shape of the branching symbol (4 in Figure 5) differs depending on the number of conditional statements (the number of folds changes).
However, the number of "folds" is at least two.

Then, 4 is created as a branch symbol having a "fold" portion corresponding to the count number. In Figure 4(d), the branch symbol is 4.
In this figure, the number of pleats J is the lowest, two.

In step S15, the character string L2 is inserted into 4 in the created branch symbol, and the conditional statement, that is, the characters [...bow...] is inserted into the "fold" part. Output to.

In step S16, a line segment l whose starting point is the tip of the "fold"
Output × to the output file according to the number of conditional statements. This is a connection line that connects the process that follows the branch with 4 to the branch symbol (see FIG. 4(d)), and in the next step 517, the PAD of the process after the branch is created.

The process in step S17 is similar to the process in step S13, and the document written in the next line of each conditional statement (the document starting with "period") is analyzed, the graphic data is created, and the output file is created. Output.

(d) If the character string Ll is not one of the characters (a) to (c), that is, if it is simply a character string starting with "゛...pa J," in step 31B, the display area H is A rectangular processing symbol (3 in FIG. 5) surrounding each coordinate value H1 to H4 is created.

In step S19, the graphic data obtained by inserting the character string L2 into 3 in the created processing symbol is output to an output file (see FIG. 4(e)).

As described above, instead of registering the graphic data of symbols corresponding to various character strings L1 in advance, we created them according to the size of the character string L2, so that they match processing names of any size. A symbol is created.

After creating symbols corresponding to various character strings L1 and writing them into the output file, in step 320, the line segment 1y is output to the output file. This is a connection line for vertically connecting each symbol, and is shown in FIG.

In step S21, the read address of the PAD description language is counted up by one, and the process returns to step S1 to repeat the above processing.

An example of the operation of each step described above is shown in FIG.
To explain part of the D description language, '5t in the first line
The art “Software Development” is loaded, and the display area H that includes the character string “Software Development” is displayed.
The coordinate values of the four corners of are calculated. 1 is created as a processing start symbol surrounding the coordinate value, and the graphic data in which "software development" is inserted in the symbol Kl and the line segment zy are written to the output file. And 'until' on the second line
'...' is read, and in the same way, 2 is created at the end position of the line segment zy in the loop symbol into which the character string 'Completion of specifications' is inserted. Then, the next line ``Create/modify specifications'' is read and created on the right side of 2 in the loop symbol. From the third line onward, the graphic data of each symbol is written to the output file in the same way, and when all the PAD description languages in one document file are written, the output file is stored as a PAD data file in the PAD storage unit 5. is stored in

The stored drawing data of the PAD is displayed on the monitor 2, and then output as printed matter from the printer 6 as required.

Note that the operation of the PAD converter 4 described above, that is, the method of creating the PAD description language, is not limited to the one described above, and other creating methods can be considered and applied.

Next, modify (move, delete) the PAD you created.

(insertion, etc.), read the document file of the corresponding PAD description language from the PAD description language storage unit I,
Make corrections on the PAD description language using keyboard 3,
In other words, instead of directly modifying PAD,
Since corrections are made using the AD description language, corrections can be made quickly without specifying the position of each symbol to be corrected and moving or deleting it.

Then, the document file is updated with the modified PAD description language. The PAD conversion unit 4 analyzes the PAD description language in the updated document file as described above, creates corrected PAD data, and converts the PAD data in the PAD storage unit 5.
D Update the data file. The updated PAD data is displayed on the monitor 2 and output from the printer 6 as necessary.

Effects of the G0 invention As is clear from the above explanation, the PAD according to this invention
The creation device is configured to analyze the document information and automatically create a PAD by inputting the symbols that make up the PAD and the process name within the symbol in a document format, so it does not work as before. Since there is no need to draw the PAD directly on the monitor, and corrections can be made in document format, the time required to create the PAD and the user's effort can be significantly reduced. Ta.

Therefore, the process of creating specifications (including PAD), which is a computer software development process, can be carried out efficiently, contributing to the efficiency of the software development process.
