Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a CASE tool, and more particularly to a technique for assigning data names such as class methods in a database of an object-oriented environment.

[0002]

2. Description of the Related Art In recent years, for the purpose of constructing an integrated database, attempts have been made for standardization for giving data item names and the like according to terms used. As a standardization method for such data item names, terms to be used are classified into three types of "main words", "partition words", and "modifiers", and the names of data items are expressed by a combination of the classified terms. The “Durell naming convention” is widely known. In this case, the "main term" is a term indicating the object to be managed, the "partition word" is a term indicating the type of value, and the "modifier" is a term for classifying the content of the target term. Is a term. According to Durell's naming rule, based on these categorized terms, the occurrence of synonyms and homonyms related to the assignment of names is suppressed.

[0003] The naming rule of Durell is extended to include not only data items but also, for example, DOA (Data Oriented Appr.).
There is also known a naming method applied to elements such as entities, attributes, domains, etc. in Oach), that is, object-oriented concepts. In this method, for example, the names of data items are standardized based on “subjects”, “partitions”, and “modifiers” defined as the divisions of terms that form the names of entities, attributes, and domains. The data item name can be automatically given by determining the entity and the domain by focusing on the fact that the data item exists at the position of the direct product of the entity and the domain name.

Further, for example, a predetermined ER model (Entity
-The above-mentioned method is applied to a CASE tool that supports the upper trend such as requirements analysis based on the -Relationship Model) and the basic design process, and there are also software that implements a mechanism to convert logical names to physical names in a straight line. Exists.
These methods are described in detail in “Automation of Data Item Naming by Extending Durell Naming Rules”, Masaki Kato, 49th Annual Convention of IPSJ, 3V-07.

[0005]

By the way, in the above-mentioned conventional method, the target range in standardizing data names is D
Only elements of entities, attributes, and domains handled by OA are included, and "methods", which are elements of an object-oriented approach, are outside the scope of name standardization. The term categories defined in the DOA are “main term”, “partition term”, and “modifier”.
And there is no term category for expressing the method name. For this reason, there is no unified assignment rule of the name to be assigned to the method name in the object orientation. There is a problem that the maintainability of the system is impaired.

For example, in software in which a mechanism for automatically converting a data name from a logical name such as a Japanese name to a physical name such as a code name is implemented, the logical name of the method name is changed to the physical name as it is. When the conversion is performed, the conversion is performed based on the Japanese expression, so that there is a problem that the function name in the program becomes an unnatural expression.

Such a problem can be solved by standardizing a method in the object orientation, that is, a data name formed including an operation word indicating an operation for a specific target event.

It is an object of the present invention to provide a data naming method which enables a regular naming of a data name formed including an operation word representing an operation for a specific target event. It is in. Another object of the present invention is to provide a data naming apparatus suitable for implementing the naming method. It is another object of the present invention to provide a recording medium suitable for realizing the above-mentioned naming method and apparatus on a general-purpose computer device.

[0009]

According to the data naming method of the present invention, which solves the above-mentioned problems, term information relating to data name forming terms for forming a name of a data group is constructed, and, for example, an external name is provided. A data logical name according to the assignment request is generated based on preset name assignment information and the term information, and a data physical name corresponding to the generated data logic name is generated based on the name assignment information and term information. And updating the data group by reflecting the generated data logical name and physical name, and defining the data logical name and physical name based on the term information and the name assignment information. It is characteristically and uniformly provided.

The naming information comprises, for example, a predetermined combination of an operation word representing an operation for a specific event and the data name forming term, and is used as information for standardizing the data logical name and physical name. Alternatively, for converting the data logical name based on a Japanese expression in which the object precedes the predicate verb into the data physical name based on an English expression in which the predicate verb precedes the object. Information.

According to the data naming apparatus of the present invention, information relating to a predetermined data name forming term for forming a name of a data group is in accordance with a predetermined name naming request and a term dictionary constructed in the form of, for example, a database. A logical name generating means for generating a data logical name based on preset name assignment information and the term dictionary, and a data physical name corresponding to the generated data logical name based on the name assignment information and the term dictionary Physical name generating means for updating the data group by reflecting the generated data logical name and physical name. If necessary, the term dictionary is constructed to be sharable with other devices.

[0012] For example, when the data corresponding to the name assignment request already exists,
The data logical name for the data is generated based on the name assignment information and the term dictionary. Alternatively, the data logical name according to the name assignment request is divided into the data name forming term units based on the term dictionary, and each of the divided data name forming terms is replaced with the corresponding standard term. Generating the data logical name.

The physical name generation means generates the data physical name by replacing the standard term group forming the generated data logical name with the corresponding physical name, based on the term dictionary, for example. . When the generated data logical name is formed including an operation word representing an operation for a specific event, the physical name corresponding to the standard term group forming the data logical name based on the term dictionary. To generate a first data physical name, and, based on the naming information, move a physical name corresponding to the operation word to a head position of the first data physical name to change the data physical name. Generate.

[0014] If the update means does not exist corresponding to the name assignment request, the update means newly saves the data comprising the generated data logical name and physical name.

The data naming apparatus applies a predetermined data item naming rule to an object-oriented concept, and generates a data logical name and a physical name related to an object-oriented method including an operation word representing an operation for a specific event. It can also be configured to be applied. When generating a data logical name related to the method, based on the predetermined data item naming rule, a class name including one or more qualifiers and at least one principal word, or at least one or more qualifiers and Identify an attribute name consisting of one principal word or one or more modifiers and at least one terminator,
It is configured to generate a data logical name corresponding to a method name composed of a combination of the specified class name or attribute name and the operation word. When a data logical name and a physical name related to the specific method are assigned, the data logical name and the physical name in the related attribute are sequentially generated and assigned to the method.

The data naming apparatus of the present invention can be used for software development support. In this case, for example, a data logical name including an abstract data model name expressed in Japanese during a software development trend is converted to a data physical name including a code name expressed in English during a software development trend. It is constituted so that.

According to the present invention, there is also provided a recording apparatus which stores a program code readable by a computer device having a term dictionary constructed to include information on predetermined data name forming terms for forming data group names. A medium is also provided. The program code is a process for generating a data logical name in accordance with an external naming request, based on preset naming information and the term dictionary, and a data physical name corresponding to the generated data logical name. And a process of generating the data group based on the name assignment information and the term dictionary, and a process of updating the data group by reflecting the generated data logical name and physical name.

[0018]

Embodiments of the present invention will be described below in detail with reference to the drawings. (First Embodiment) FIG. 1 is a functional block diagram showing an embodiment of a data naming apparatus to which the present invention is applied. The data naming apparatus 1 is formed by reading and executing a database 15 (hereinafter, DB15) and a term dictionary 16 built in an internal or external storage device of the computer device and a predetermined program code by the computer device. The database control unit 11 (hereinafter, referred to as
DB control unit 11), logical name assignment processing unit 12, physical name assignment processing unit 13, and name assignment information holding unit 14.

The program code is usually stored in an internal or external storage device of the computer, and is read and executed as needed. However, the present invention can be implemented as long as the above functional blocks can be formed in a computer device. For example, a portable recording medium such as a CD-ROM or an FD, which can be separated from the computer device, or connected to a network. The program may be recorded in a program server or the like, read at the time of use, installed in the computer device or in an external storage device, and provided for execution at any time.
Note that the functional blocks may be realized by substituting a part of an operating system (OS) installed in a computer device or using a part of the function of the OS.

The DB 15 is, for example, a predetermined object-oriented database constructed including an object-oriented concept. The term dictionary 16 is constructed to include definition information on data name forming terms (hereinafter abbreviated as “terms”) forming data names given to data groups in the DB 15. In particular,
Information on "standard terms", "physical names", "general terms", and "term categories" are constructed in association with each other, and "standard terms" are used as standard in term groups. A unique term group, that is, a defined data logical name group for name standardization is described, and a "physical name" describes a data physical name group such as a code name corresponding to each standard term. Things. Also,
The “general term” is a group term that describes one or more synonymous vocabularies generally used in a naming request or the like, and the “term category” includes “modifier”, “headword” , "Partition word", and "operation word" are described. The term type will be described later.

The DB control unit 11 receives a name assignment request for a data group in the DB 15 made by an operator or the like via an input interface (not shown), and acquires and updates data in the DB 15 based on the request. It is.

The logical name assignment processing unit 12 is a DB control unit 1
In response to a name assignment request from No. 1, a corresponding data logical name is generated based on the name assignment information held in the name assignment information holding unit 14 and the term dictionary 16. Further, the generated data logical name is reflected and added to the data group in the DB 15 via the DB control unit 11.

The physical name assignment processing unit 13 stores the data physical name corresponding to the data logical name generated by the logical name assignment processing unit 12 in the name assignment information and term dictionary 16 held in the name assignment information holding unit 14. It is generated based on this. Further, the generated data physical name is reflected and given to the data group in the DB 15 via the DB control unit 11.

The name assignment information holding unit 14 holds information including rules for assigning data logical names and physical names to data groups in the DB 15. Details regarding the name assignment information will be described later.

Next, the details of the present embodiment will be specifically described. First, the data naming method according to the present invention relates to, for example, standardization of method names in object orientation. “Method” means an operation on a specific object or an attribute included in the specific object.
Therefore, in the present invention, the naming standard in the method is “object name + operation word” or “attribute name + operation word”. The “operation word” in this case is a term expressing an operation for a specific target event, and is, for example, a verb such as “acquire”, “set”, “calculate”, and the like. The word "acquisition",
It is defined by terms such as “setting” and “calculation”.

FIG. 2 is a conceptual diagram showing a naming standard in a method. In the example in the figure, “new_customer_registration” and “new_customer_phone_number_
The term "acquisition" is used to represent a group of terms. Also,
The class name is formed from a combination of the terms "arbitrary" which can be specified arbitrarily and the "subject" which is required in the singular. It is formed by a combination of the terms "main word" essential for singular designation, "modifier" that can be arbitrarily designated plural, and "partition word" essential for singular designation. The class name in (a) in the figure is “new_customer”, and the attribute name in (b) in the figure is “new_customer”.
Customer_telephone_number ".

Looking at the above in terms of combinations of terms,
The method name can be any multiple “modifier” that can be specified, the “main word” that is required for singular, and the “operation word” that is required for singular.
Combination or any of the plural qualifiers that can be specified, the singular designation of the "main word", the plural qualifiers that can be specified, the singular designation of the "partition word", and the singular designation Is formed from a combination of the terms "operation word" which is indispensable. The types of these terms are based on, for example, the well-known Durell data item naming rules.

In a method of assigning a data physical name corresponding to a data logical name, generally, a data physical name is often expressed in English such as a code name. The order of “+ verbs” is reversed. For example, when the method name of “name_setting” is translated into English, it becomes “Set_name”. Furthermore, since it is often more natural to express the operation words in English, when replacing the Japanese data logical name with the data physical name, the operation word is moved to the top to form the data physical name. And

Therefore, in the present embodiment, information such as the above-mentioned naming standard is held in the naming information holding unit 14, and a data logical name and a physical name according to the naming request are given based on the information. Things.

Next, a processing procedure in the data naming apparatus 1 shown in FIG. 3 will be described with reference to a schematic diagram in the naming processing of FIG. The operator or the like inputs a name assignment request including a data name to be standardized through an input interface (not shown) (step S101).
The name assignment request in this case is, for example, designation information such as a function name related to a method in the object orientation.
The DB control unit 11 acquires the name assignment request, and retrieves and acquires corresponding data from the DB 15 (step S102). In the example of FIG. 4, a request for giving a method name “acquire new employee name” is made.

The logical name assignment processing unit 12 includes a term dictionary 16
It is determined whether or not the naming request acquired by the DB control unit 11 is formed from the vocabulary in the term dictionary 16 based on (step S103). If the vocabulary that does not exist in the term dictionary 16 is included in the name assignment request (step S103: No), for example, an error message is output, and the process is appropriately terminated (step S104). On the other hand, the name assignment request is sent to the term dictionary 16
(Step S103: Yes), the naming request is divided into predetermined terms based on the term dictionary 16 (step S105).
Specifically, the method name is looped by the character string of the method name, and the method name is divided into predetermined term units with reference to the term dictionary 16. In the example of FIG. Is divided into term units of “new_employee_name_acquisition”.

Further, the logical name assignment processing unit 12 derives a data logical name from the sequence of terms in the term assignment request divided into terms based on the term assignment information held in the term dictionary 16 and the name assignment information holding unit 14. It is generated (step S106). Specifically, the order of the terms is checked by looping over the number of terms forming the method name, and if each term is a general term, the general term is replaced with a standard term based on the term dictionary 16. . In the example of FIG. 4, "new_employee_name_acquisition" divided into term units is replaced with a standard name of "new_employee_name_acquisition". By this replacement, a standardized data logical name is generated. Further, when the arrangement order of terms contrary to the naming information in the naming information holding unit 14 is detected, for example, an error message or the like may be output and the processing may be terminated.

Next, the physical name assignment processing unit 13 generates a data physical name for the data logical name generated in step S106 based on the term dictionary 16 (step S107). Specifically, a loop is performed for the number of terms forming the method name, and the physical name corresponding to each standard term is acquired by referring to the term dictionary 16 to generate a data physical name. In the example of FIG. 4, the data logical name “new_
"New_Emp_Nam" corresponding to "Employee_Name_Acquisition"
A data physical name “e_Get” has been generated.
Further, the physical name assignment processing unit 13 rearranges terms in the generated data physical name based on the name assignment information held in the name assignment information holding unit 14 to generate a final data physical name. In the example of FIG. 4, by moving the operation word at the end of the method physical name to the head of the physical name, “New_Emp_Name_Ge
From the data physical name “t”, “Get_New_E”
mp_Name ”has been updated to the data physical name.

Next, the DB control unit 11 reflects the data logical name generated in step S106 and the data physical name generated in step S107 on the DB 15, reflecting the name, and updates the DB 15. (Step S108). In the example of FIG. 4, the method logical name after the name standardization is “new employee_name_name_acquisition”, and the method physical name is “Get_New_Em”.
p_Name ”. In the process of step S109, when a name assignment request for new data to be assigned a name is input (step S109:
Yes), returning to step S101 and repeating the processing.

In the above processing procedure diagram, a case has been described where data to be given a name is retrieved from the DB 15 and a data logical name and a physical name are given.
In the case where a data logical name and a physical name in accordance with the name assignment request for data that does not exist in No. 5 are assigned, the data logical name and the physical name are based on the input name assignment request without performing step S102. The data may be reflected in the DB 15 by newly generating it.

When the name assignment request relates to a method name in the object orientation, for example, the data logical name and the physical name of the method generated in the process in steps S101 to S107 are related to the method. The data logical name and the physical name in the attribute (attribute) may be sequentially generated and assigned so that the standardized method name spreads.

In the present embodiment, a pair of the DB 15 and the corresponding term dictionary 16 has been described. However, the present invention is not limited to the above-described embodiment. For example, a plurality of databases may be constructed and correspond to each database. A plurality of term dictionaries 16 may be provided. In this case, each term dictionary 16 may be configured to be sharable in each database so that it can be applied to other than a specific database. Furthermore, by constructing the term dictionary 16 itself in the form of a database, for example, a highly convenient embodiment is realized.

The above-mentioned data naming apparatus 1 can be configured as a software development support apparatus adapted to function as a CASE tool for supporting software development, for example. In this case, for example, a data logical name including an abstract data model name such as a class name expressed in Japanese during a software development trend is replaced with a data name including a code name expressed in English during a software development trend. What is necessary is just to comprise so that it may be converted into a physical name.

As described above, in the data naming apparatus 1 of the present embodiment, the naming information for standardizing the data name such as the method name formed by including the operation word representing the operation for the specific target event is used. Based on this, it is possible to assign a regular name to “methods” which are object-oriented elements that are not subject to name standardization in the conventional method.

Further, based on the naming information and the term dictionary 16, it is possible to automatically convert a data logical name such as a code name from a data logical name such as a Japanese name in a method or the like.
"Calculation" is changed to the data physical name "Calc_Balance"
As described above, it is possible to convert a Japanese expression in which the order of terms is "object + predicate verb" to a natural English expression in which the unnaturalness of "predicate verb + object" is eliminated.

An operator, such as a system administrator, changes information in the term dictionary 16 so that the DB 15
All the method names in can be automatically renamed.

For example, by constructing the term dictionary 16 in the form of a database so that it can be shared by a plurality of systems or the like, the reusability of the defined terms is enhanced.

When this embodiment is applied to an object-oriented software development system or the like,
Since it is possible to automatically replace the function names of the methods owned by the class with standardized data names,
In the development system, method names are unified without duplication, and the maintainability and productivity of the system are greatly improved.

[0044]

As is apparent from the above description, according to the present invention, it is possible to give a regular name relating to a data name formed including an operation word representing an operation for a specific target event. There is an effect. Further, when the present invention is applied to an object-oriented concept, there is a specific effect that a regular name can be given to a method in the object orientation.
