Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an object-oriented analysis / design support apparatus for supporting analysis and design by an object-oriented analysis / design method in software development.

[0002]

2. Description of the Related Art In general, object-oriented is a concept of developing software by using "things (objects)" in the real world as constituent units, and various variations of object-oriented analysis and design methods have recently been proposed (for example, , References: [1] J. Rumbaugh et al (Translated by Hanyuda): Object-Oriented Methodology OMT, Toppan, 1992, [2] S.Shlaer, SJMellor (Translated by Hoichida, Toru Yamaguchi): Object-Oriented Systems Analysis, Kei Gaku Shuppan, 1992, etc.).

At this stage, the words used in each analysis and design method are slightly different, so the terms used in this specification will be defined first. First, in the present specification, the word "object" is hereinafter referred to as "object-oriented".
It will be used only in the form. Individual "things" in the real world are called "instances", and the concept that each "instance" has in common is called a "class." Further, in the software world, what corresponds to individual data is called an “instance”, and information (called “attribute”) and operation (called “method”) that each “instance” has in common is described. The model of an instance is called a "class".

A software program developed on the basis of the object-oriented analysis and design method is composed of classes. The class describes the data that the instances of the class have in common and the operations that can be performed on the instance of the class. When the program is executed, instances of each class are created and possible operations are performed on those instances. There can be multiple instances of one class.

For example, in an online system of a financial institution, there is a class "account" on the program,
There are attributes (account number, balance, etc.) that each account has in common and methods (depositing operation, withdrawing operation, etc.)
Is described. An "account" instance is an individual account that actually exists when the system is operating. Each “account” instance has the value of the attribute declared in the “account” class as data, and can be operated by the method described in the “account” class.

By the way, even in most of the object-oriented analysis and design methods, software analysis and design are carried out using several types of diagrams unique to the method (referred to as "analysis design diagrams" in this specification). The analytical blueprint is
Although there are small differences for each method variation, for example, a class relation diagram, a state transition diagram, a data flow diagram, etc. Even if there are several types of diagrams, the structure of software is complicated, so that a large number of analysis design diagrams are often used in actual analysis design. In addition, the analysis design diagrams are closely related to each other, and maintaining the consistency is a great burden on software development.

Therefore, a number of object-oriented analysis / design support apparatuses have been proposed in the past as apparatuses for supporting object-oriented analysis / design. The object-oriented analysis design support device has an editor for editing an analysis design drawing, and has a high level of integrity such as maintaining consistency between a plurality of analysis design drawings and automatic generation of a program based on the analysis design drawing. There are also those that perform processing.

[0008] One of the major characteristics of object orientation is that, when new software is developed, partial reuse of the software in units of classes becomes easy and software development becomes efficient. Further, in recent years, not only the reuse at the program level but also the reuse of the class at the analysis and design stage is required. And the analysis design drawing obtained by the analysis design of the past software is
In the object-oriented analysis design support device, since it exists as analysis design information that represents the contents of the analysis design drawing, if this analysis design information is saved, reuse of the analysis design drawing is also possible conceptually. Becomes

[0009]

On the other hand, in the conventional object-oriented analysis and design support device, it was not possible to select or extract information from the stored information in class units. Was difficult to reuse. In other words, object-oriented software will eventually be configured on a class-by-class basis, but each analysis blueprint represents one aspect of an object, and information about a single class is also included. At the analysis and design stage, these several types of analysis and design drawings are distributed. Also, it is often the case that one class has a relationship with another. Therefore, in order to obtain complete information on a certain class from the stored information, it is necessary to comprehensively collect all the information on the class from the information distributed in these several types of figures.

In this respect, in the conventional object-oriented analysis and design support apparatus, information on a certain class distributed in several types of analysis design drawings is extracted all at once, or information on a certain class is extracted. It was not possible to selectively retrieve what was needed from the stored information and reuse it. As a result, there is a problem that it is difficult to reuse the stored information in units of classes.

Certainly, some conventional object-oriented analysis and design support apparatuses can copy all or part of the analysis design drawing, and it is conceivable that the stored information can be reused by this function. However, such a copy is mechanical as in a conventional general-purpose graphic editor, and in order to extract information on a class-by-class basis, the user needs to search through a large amount of stored information, A huge amount of work was required to judge the information and copy it individually.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and an object thereof is to provide an object-oriented analysis and design support device that facilitates reuse of stored information in class units. Is to provide. Another object of the present invention is to provide an object-oriented analysis and design support device in which it is easy to select a class included in reuse of stored information. Still another object of the present invention is to
An object of the present invention is to provide an object-oriented analysis and design support device that effectively utilizes a resource of stored information.

In order to achieve the above object, the object-oriented analysis and design support apparatus according to claim 1 is
Analysis design drawing input means for inputting an analysis design drawing that is a plurality of types of drawings used for object-oriented analysis design of software, and analysis design information representing the contents of the analysis design drawing as saved information for reuse. Included in the save information is storage information storage means for storing each type of the analysis design drawing, target information storage means for storing target information that is information indicating the content of the analysis design drawing related to new software. Of the classes, a class selecting means for selecting a selected class which is a class to be reused in the analysis design of the new software, and the new one of the types of the analysis design drawing related to the storage information. From range selection means for selecting a selection range of the type to be reused in software analysis design, and the saved information, Reuse processing means for reusing the saved information by extracting the reuse information that is the saved information related to the selected class and the selected range, and adding this reuse information to the target information. It is characterized by

According to a second aspect of the present invention, in the object-oriented analysis design support apparatus according to the first aspect, among the classes included in the saved information, another class having a predetermined relationship with the selected class is related. It has a related class selection means for selecting a class as the selected class.

According to a third aspect of the present invention, in the object-oriented analysis design support apparatus according to the first aspect, the reuse processing means copies the reuse information to the target information as a mode of the reuse. It is configured such that a first mode for performing the above and a second mode for adding predetermined data referring to the reuse information to the target information can be selected.

[0016]

The present invention having the above structure has the following functions. That is, in the invention of claim 1, the input analysis design information of the analysis design drawing is stored in the storage information storage means as storage information. When reusing this stored information in analysis and design of new software, the user selects the selected class by the class selection means,
The selection range is selected by the range selection means. The reuse processing means extracts the reuse information, which is the save information related to the selected class and the selection range, from the save information, and reuses the save information by adding the reuse information to the target information. As described above, according to the first aspect of the invention, if the desired class and range are selected, the corresponding saved information is added to the target information, so that the saved information can be reused easily.

Further, in the invention of claim 2, the related class selecting means can select the related class which is another class having a predetermined relationship with the selected class as the selected class, so that the related class can be reused easily. .

According to the third aspect of the present invention, the reuse mode can be selected. According to the first mode, the reuse information is copied and added to the target information. The original saved information will not be lost even if is changed. Further, according to the second aspect, since the predetermined data referencing the reuse information is added to the target information, the reuse information in the stored information is only changed and the reuse information is referred to. The change can be reflected in the analysis and design information of all software. As described above, according to the third aspect of the present invention, since the reuse mode suitable for the property of the saved information to be reused can be selected, the resource of the saved information can be effectively utilized.

(2) Operation and effect of the embodiment [1. Analytical design] The analytical design of software in this apparatus is performed by editing and inputting an analytical design drawing and various processes for the analytical design drawing.

[1-1. Analysis Design Drawing] Here, the analysis design drawing in this apparatus is unique to the object-oriented analysis design method supported by this apparatus. Specifically, these analysis design diagrams are a class relation diagram, a data flow diagram, and a state transition diagram. The user can input these figures to the input / output unit 1
And input using the analysis design drawing input unit 2. Here, FIGS. 2, 3 and 4 are examples of a class relation diagram, a data flow diagram, and a state transition diagram, respectively.

Although not shown, incidental information of each figure (for example, method argument type) may be input together with each figure from the input / output unit 1 and the analysis design drawing input unit 2.

[1-1-1. Class Relation Diagram] Among the analysis design diagrams in this apparatus, the class relation diagram is a list in which the classes extracted at the time of analysis design are listed and the relation between them is described ( (Fig. 2). In FIG. 2, three classes, class1, class2, and class3, are represented by squares with rounded corners. The letters in each rectangle represent the class name, the attribute name included in the class, and the method name included in the class from the top. For example, class1 has one attribute (attr11) and two.
It has two methods (meth11, meth12). The attribute means the data of the instance of the class, and the method means the function of the instance of the class.

Relationship lines are shown between the classes according to the relationships between the classes. For example, there is an is_a relationship between class1 and class2, and in FIG. 2, a relationship line (arrow) labeled as “is_a” is shown. this is,
class2 indicates that it is a subclass of class1.
Although not shown, detailed specifications of the class (for example,
Attributes and method types) may also be input from the input / output unit 1 and the analysis design drawing input unit 2.

[1-1-2. Data Flow Diagram] The data flow diagram describes the data flow between the instances (FIG. 3). In Figure 3, the instance of class1 "ins
t1 ”, instance of class2“ inst2 ”, class3
3 instances of “inst3” are represented, and each instance is labeled as “instance name.class name”.

Further, in FIG. 3, message flows inside and outside the instance and data accompanying them are described. For example, meth11 from inst1 to meth from inst2
The directed line to 21 represents the message transfer from meth11 to meth21. Also, meth12 to meth in inst1
The directed line to 11 represents message transfer from meth12 to meth11 in inst1. Although not shown, the data sent with these messages may be input from the input / output unit 1 and the analysis design drawing input unit 2.

[1-1-3. State Transition Diagram] The state transition diagram is described one for each class and represents the behavior of an instance of the class (FIG. 4). FIG. 4 is a state transition diagram of class1 and includes two states, state1 and state2. That is, the instance of class1 is
When the event called th11 is received, the state changes to state2, and when the event called meth12 is received in state2, stat
The status changes to e1. Although not shown in the drawing, the operation performed in association with these transitions and the conditions for causing the transitions may be input from the input / output unit 1 and the analysis design drawing input unit 2.

Here, it is assumed that the software analysis design is performed using the analysis design diagrams of FIGS. 2 to 4. FIG. 5 collectively shows the analysis design drawing used for this analysis design. These analysis blueprints consist of one class relationship diagram, one data flow diagram, and the number of classes (ie 3
It is a state transition diagram of (sheet).

In these analysis design drawings, for example, class1
Information about class1 is scattered in class1 of the class relation diagram and other related classes, instances of class1 in the data flow diagram and instances of other classes that exchange messages with them, state transition diagram of class1.

[1-2. Analytical Design Information] The analytical design diagrams shown in FIGS. 2 to 5 are displayed as figures and characters on the CRT of the input / output unit 1, but in the internal representation of this device, each analytical design is shown. It is the analysis design information showing the contents of the figure. Then, during the analysis design, the analysis design information is stored in the target information storage unit 5 as the target information, but when one analysis design is completed, the storage information is stored as the storage information with a predetermined group name. Stored in section 4. The analysis design information is data in a predetermined form, and specifically, class information indicating the contents of the class relation diagram, class relation diagram information, data flow diagram information indicating the contents of the data flow diagram, contents of the state transition diagram. State transition diagram information is included. Further, the data includes graphic position information of each analysis design drawing.

These class information, class relation diagram information, data flow diagram information, state transition diagram information, and graphic position information are as follows:
After the analysis and design are completed, they are stored separately and independently in a predetermined area in the storage information storage unit 4. It should be noted that when the user performs a predetermined operation, the program generation unit 9 automatically generates a program in a predetermined programming language from these analysis design information (hereinafter, the program automatically generated in this way is referred to as an "automatic generation program"). The automatic generation program is stored in the target information storage unit 5 and the storage information storage unit 4 as information according to the analysis design information. Next, the specific content of the analysis design information will be described.

[1-2-1. Class Information] First, the class information is information about attributes and methods of each class. Specifically, for each class in the class relation diagram, the class name,
It represents attribute names, method names, and their types. An example of class information corresponding to the class relation diagram of FIG. 2 is shown below.

[0038]

[1-2-2. Class Relationship Diagram Information] The class relationship diagram information represents the relationships between the classes described in the class relationship diagram, and corresponds to the class relationship diagram of FIG. An example of diagram information is shown below.

Is_a (class1, class2); has_a (class1, class3);

This example means that "class1 and class2 have an is_a relationship" and "class1 and class3 have a has_a relationship". The position of the graphic of the class in the class relation diagram is represented by graphic position information described later.

[1-2-3. Data Flow Diagram Information] Next, the data flow diagram information represents the message flow in the data flow diagram and the data sent with it.
Specifically, the information in the instances existing in the data flow diagram is listed first for each instance, and then the message flows between the instances are listed. An example of data flow diagram information corresponding to the data flow diagram of FIG. 3 is shown below.

[0043]

In this data flow diagram information, first in
The message flow in st1 is represented. In this item, first, the attributes and methods existing in inst1 are expressed including relative position information in the instance, and then the message flow in the instance is expressed. For example, the second line indicates that the attribute attr11 exists at the relative position (5, 10), and the fifth line sends a message from the attribute attr11 to meth12. It is shown that the data of () flows.

After all the message flows in the instance are enumerated in this way, the message flow flowing between the instances is represented. For example, on lines 12 to 13, meth11 in class inst1 to inst in class2
A message is sent to meth21 of 2 and the integer type is accompanied.
It shows that the data of (int) flows. The position of the instance in the data flow diagram is represented by graphic position information described later.

[1-2-4. State Transition Diagram Information] The state transition diagram information represents the information described in the state transition diagram for each class.
An example of the state transition diagram information corresponding to the state transition diagram of FIG. 4 is shown below.

[0047]

In this state transition diagram information, the state name and the position of the rectangle representing the state are listed first, and then the transitions between the states are listed. Information such as an operation performed in accordance with a transition and a condition for the transition to occur is also represented in the state transition diagram information, but it is omitted here because it is not directly related to the description of reuse on a class-by-class basis.

[1-2-5. Graphic Position Information] The graphic position information is
Represents the position of a class or instance in the class relationship diagram and data flow diagram. An example of graphic position information corresponding to each of FIGS. 2 and 3 is shown below.

[0050]

That is, crd represents the graphic position of the class in the class relation diagram, and dfd represents the graphic position of the instance in the data flow diagram. Since such position information is not directly used for reuse, it is thus stored separately from other analysis design drawings.

[1-2-6. Automatically generated program] By the way,
A part of the automatic generation program generated based on the analysis design information as described above will be illustrated below.

[0053]

The user can make appropriate modifications to this program to obtain the final program. In addition,
The specific procedure of the automatic program generation is not directly related to the present invention and there are many known techniques, so the description thereof will be omitted here.

The analysis design information as described above is shown in FIG. That is, as a result of the analysis design up to the generation of the automatic generation program, the information as shown in FIG. 6 is stored in the target information storage unit 5, and if the analysis design drawing and the automatic generation program are collectively shown, as shown in FIG. Become.

[2. Class Reuse] The user can reuse the stored information in units of classes by using the class selecting unit 6, range selecting unit 7, and reuse processing unit 8. In addition,
The analysis design information, which is stored information, represents not the image information itself of the analysis design drawing but the logical content described in the analysis design drawing. The analysis design information includes C of the input / output unit 1.
Sufficient information is included in the RT to reproduce the analytical design drawing. From the user's point of view, the reuse of the class is the reuse of the class represented in the analysis design drawing, but it is not the image information itself that is actually reused inside the object-oriented analysis design support device, but the analysis design. Information.

Here, the analysis design information illustrated up to FIG. 7 is regarded as the storage information, and the reuse of the storage information at the time of a new analysis design will be described.

Thereafter, in this embodiment, the storage information is changed to "old_
Label as "data". The content of this saved information is
As shown in FIG. 6 and FIG. 7, the program includes an automatic generation program, and is stored in the saved information storage unit 4 when the analysis design of the program (software) is completed.

On the other hand, FIG. 8 is an analysis design drawing related to the new software. In this analysis design drawing, one class class4 exists in the class relational drawing, and an instance inst4 of class4 exists in the data flow drawing.
The state transition diagram has not been described yet. The program has not been generated yet. This new software analysis design information is stored in the target information storage unit 5 as target information as shown in FIG.

Next, FIG. 10 is a flow chart showing the procedure of reuse. That is, in this procedure, the user first selects a group of stored information through the class selection unit 6 (step 101) and also selects a selected class to be reused from the group (step 10).
2). Subsequently, the user selects the type of analysis design drawing to be reused in the selected class as the selection range (step 103), and further selects and instructs the reuse processing unit 8 (step 104). The processing unit 8 adds the reuse information related to the selected class and the selected range of the stored information to the target information.

[2-1. Group Selection] First, the user
One of the analysis design information to be reused is selected from the plurality of groups of stored information. Here, the input / output unit 1 is a multi-window man-machine interface system equipped with input / output devices such as a CRT, a mouse and a keyboard, and the class selection unit 6 is a class reuse window as illustrated in FIG. Is displayed on the CRT of the input / output unit 1. This window also serves as an input panel. Specifically, you can select a group by clicking the "Analysis design information selection" button with the mouse cursor. Similarly, the "related class selection" button and the "reuse range selection" button can also be selected in the class selection section. 6 and the function of the range selection unit 7 are supported. Further, the “copy” button and the “reference” button indicate the reuse mode as the reuse processing unit 8
Used to instruct. The user makes input for reuse through this window.

For example, when the "analysis design information selection" button in the window is clicked, a list of groups of save information stored in the save information storage unit 4 at that time is displayed on the CRT.
Is displayed like a menu, and the user selects one of them and clicks it. When the group of saved information to be reused is selected in this way, the class relation diagram is displayed on the window.

[2-2. Class Selection] After selecting a group, the user uses the class selecting unit 6 to select a class to be reused. This selection can be performed by clicking the desired class among the classes displayed in the window. A plurality of classes can be selected, and the classes may be directly selected one by one, but another class related to the directly selected class may be selected by clicking the "related class selection button" in the window. Here, as the content of the relation, various kinds such as "all classes having direct is_a relationship" and "recursively all classes having has_a relationship" are conceivable, and may be set freely.

Here, as an example, class1 is first selected, and then "all classes that have a direct is_a relationship" with class1 are selected. As a result, class2 is also selected. As a result, classes class1 and class2 are reused classes. Shall be selected as.

[2-3. Selection of range] In the storage information, as information related to each class, a class declaration (class name and attribute or method declaration) and an instance of the class in the data flow diagram are related. Information, the state transition diagram of the class, and the information related to the class exist in the automatic generation program of the class. Therefore, the user then further specifies the range of information to be reused for each class by the type of these figures and the type of programs.

Of these, the user cannot select the first "class declaration". When reusing a class, at least the class declaration is reused. The user can freely select whether or not to reuse the three items other than the “class declaration”. In other words, the information about the instance of the class in the data flow diagram, the state transition diagram of the class, and the information related to the class in the automatic generation program of the class, the data for each class to be reused. The user chooses whether to reuse the flow diagram information.

Here, the data flow diagrams of both class1 and class2 will be reused. Then, for each class to be reused, the user selects whether to also reuse the state transition diagram information. Here, only the state transition diagram of class1 will be reused. Further, for each class to be reused, the user selects whether to also reuse the information of the automatically generated program at the same time. This automatic generation program is a program corrected by the user to the program automatically generated by the program generation unit 25. Here class1
Only the automatically generated program of will be reused. The combination of the selection class and the selection range selected as described above is collectively shown in FIG.

[2-4. Reuse Processing] When the selection of the class and the range is completed and the user instructs a reuse mode (described later), the reuse processing section 8 selects the selected class and selection from the stored information. The saved information is reused by extracting the reuse information that is the saved information related to the range and adding this reuse information to the target information. That is, the analysis design drawing is stored separately for each type of information, and the analysis design information of each type is also stored for each class or including a description about the class. Therefore, in order to capture the information of the class and range, search the analysis design information based on the selected class and the selected range, read the corresponding information, and add the read information to the storage area of the current analysis design information. do it.

For example, in the analysis design information (FIG. 10) of the new software corresponding to the analysis design drawing of FIG. 8, and in the storage information (FIG. 6) corresponding to the analysis design drawing of FIG. 7, the portion shown in FIG. When reused and added, the analysis design drawing immediately after reuse has the contents collectively shown in FIG.

That is, in FIG. 13, first, in the class relation diagram, the class to be reused is arranged at the right end of the diagram. Also, in the data flow diagram, an instance of the class to be reused is placed at the right end of the diagram. Also, in the state transition diagram, the state transition diagram of the class to be reused was added as it is. Moreover, in the automatic generation program, the automatic generation program of the class to be reused is added as it is.

[2-5. Mode of Reuse] By the way, two modes of copying and reference can be selected as modes of reusing the stored information. This mode can be selected by clicking the "copy" button or "reference" on the window (FIG. 11). In any of the modes, the contents of the analysis design drawing immediately after reuse are the same, but the contents of the target information immediately after reuse differ depending on the mode. Here, FIG. 14 and FIG. 15 are diagrams showing the contents of the target information in the case of copying and referencing, respectively, and refer indicates reference.

[2-5-1. Copy] That is, in "copy",
The reuse information in the stored information is copied and added to the target information as independent of the original information. Therefore, the reused part of the target information can be modified in the target information without limitation regardless of the original, and the content of the modification does not affect the original at all. For this reason, the past information is general and general, and the target information does not lose the original even when part of the reuse information is batched (corrected) or optimized (optimized). There are advantages.

[2-5-2. Reference] On the other hand, in “Reference”, the reuse information is not copied, and only the predetermined data indicating the reuse information is added to the target information. .
Then, every time the content of the target information is displayed or the analysis and design are performed, the reuse information is read from the stored information and used. Therefore, the reuse part is only projected on the target information, and there is a limitation that the original cannot be modified in the analysis design for the target information. However, if the stored information itself is corrected, the correction is automatically reflected on all other software that refers to the stored information, so that there is an advantage that the software can be easily modified.

That is, FIG. 14 shows the target information obtained by copying, and in comparison with the storage information (FIG. 6), in the five types of information other than the graphic position information, the reuse information is copied and added to the target information. There is. Note that the figure position information indicates that the diagram to be reused has been moved in parallel to the right so as to be located at the right end in the class relation diagram and the data flow diagram.

On the other hand, FIG. 15 shows the target information by reference, and in comparison with the storage information (FIG. 6), the reuse information itself is not included in the target information, and only the data refer indicating the reference and the target description are included. include. For example, in the fifth line of the class information in FIG. 15, refer old_data. c
It is described as "lass1;". This description indicates that the class1 of the class information of the storage information "old_data" is referenced. In this way, 5 other than the figure position information
In the type information, the information to be reused is “referenced”. As the figure position information, the figure to be reused is shown to be moved in parallel to the right so as to be located at the right end in the class relation diagram and the data flow diagram.

(3) Other Embodiments The present invention is not limited to the above embodiments,
The following other examples are also included. For example, since the specific type of the analysis design drawing differs depending on the object-oriented analysis design method supported by the object-oriented analysis design support device, the information to be reused accompanying the type or class of the analysis design drawing in the present invention is used. Are not limited to the types such as the data flow diagram and the state transition diagram in the above embodiment. That is, in the object-oriented analysis and design support apparatus that supports other object-oriented analysis and design methods, it is possible to use other analysis and design drawings such as an instance configuration diagram. In that case, information to be reused accompanying a class is used. The range of can be changed accordingly.

The storage information is stored for each type of analysis design drawing, but "by type" is sufficient if the information can be read out by distinguishing it by type, and is not necessarily a separate file or separate file. It need not be stored in storage. Further, the range of analysis design information to be reused may be determined not only by class and type but also by other criteria. For example, more detailed information, such as the specifications of each method, may be selected as independent of the reuse of the analytical blueprint itself. Also, the expression format of the analysis design information is free, and in the above-mentioned embodiment, it is expressed by a character string such as a keyword expressing the content, but it is expressed by a predetermined data such as a code indicating an element or meaning between elements. May be. Also,
It is of course possible to treat a character string such as a source code by treating it as an analysis design drawing or analysis design information.

Further, in the above embodiment, “copy” and “reference” are premised on selecting all kinds of information at once, but the objects of reuse are individually selected according to the kind of analysis design drawing. You may make it selectable. For example, refer to the state transition diagram, but copy the automatically generated program,
Selection such as is also possible.

Although the object-oriented analysis and design support apparatus of the above embodiment is implemented on a computer, some of its functions may be implemented on a dedicated electronic circuit.

Although the stored information in the present invention can be reused, the stored information storage means may store the analysis design information as the stored information just for recording. Further, the storage information storage means and the target information storage means in the present invention may be respectively configured on an external storage device such as a hard disk or on an internal storage device (memory). The save information storage means and the target information storage means may be configured on the same storage device in terms of hardware, and the save information stored in the save information storage means may be stored in the target information storage means. It is also possible to call it as target information and configure it so that analysis design can be performed again.
