Abstract

PURPOSE:To keep the reliability of the specifications having the data of the same contents among specifications (assembly data) which are used for development of the software using a computer. CONSTITUTION:A related file 5 shows the contents data included in the specifications in response to the name of specifications. An exclusive information file 6 shows the exclusive control state of each contents data. When an access is given to some specifications, the file 6 corresponding to all contents data shown by the file 5 is updated into an 'exclusive control mode'. Then other accesses are inhibited to other assembly data of the same contents.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to an exclusive control method in an information processing system, and in particular, in the development of computer-based software, it is possible to efficiently perform exclusive control over shared data, and to create a repository for managing information related to software development. The present invention relates to an exclusive control method suitable for improving reliability.

2. Description of the Related Art Conventionally, in data processing systems, exclusive control has been performed on a table-by-table or record-by-record basis. For example, if a record being updated by a certain task is processed by another task, the updated record will be destroyed. For this reason, when a certain program is processing data, it must be interlocked (locked) and
Updates by other programs are prohibited. After the process was completed, it was unlocked (released) and allowed to be used by other programs that had been kept waiting.

[0003] Further, as a conventional technique for performing exclusive control in a wider range than the table or record units, there is a technique described in, for example, Japanese Patent Laid-Open No. 62-282337. This technology classifies data that requires exclusive control into sets and then hierarchizes the sets. When accessing a certain set, you can access data in all sets that are lower in hierarchy than that set. This made it possible to prohibit the

On the other hand, currently, computer-based software development technology has made it possible to perform software development work that was traditionally done with paper and pencil in an interactive manner on the screen of a workstation. ing. In this case, all data related to software development, such as definition information, design results, the program itself, and test results, is stored in an information database called a "repository" so that it can be shared between each software development process. I have to. This makes it possible to significantly improve the efficiency of software development.

[0005] Specifications created in the design process such as software development include data with the same content and data that are expressed differently but are related to each other, and there are many cases in which the data are related to each other. However, in conventional systems that use workstations to create these specifications, exclusive control over data written in one specification and the same data written in another specification is not possible. There wasn't. This is because conventional exclusive control allows the system to exclusively and exclusively use the data being accessed, and although the content is the same as that data,
This is because it was not possible to prevent other users from accessing data that existed in other specifications.

[0006] Also, in the technique described in Japanese Patent Laid-Open Publication No. 62-28337, data is classified into a plurality of sets, and these sets are hierarchized to perform exclusive control on a layer-by-layer basis. It does not take into account the fact that there are also data that are expressed differently and interrelated data.

[0007]

The problem to be solved is that exclusive control over data used in computer-based software development cannot be exercised over a plurality of specifications. The purpose of the present invention is to provide an exclusive control method that solves the problems of these conventional techniques, increases the reliability of data used in computer-based software development, and makes it possible to improve the performance and reliability of a software development system. It is.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the exclusive control method of the present invention provides: (1) Based on an input access request, from a plurality of data stored in a storage medium,

[Operation] In the present invention, related information between the specifications (collective data) used for computer-based software development and the content data described in this specification (data included in the aggregate data) is held in related files. do. Also,
The exclusion information file holds information indicating the exclusion status of each content data unit. When accessing a certain specification, each content data described in this specification is detected from related files, and the exclusive information file corresponding to each content data is searched. At this time, the exclusive information file is under exclusive control, that is, one of the searched content data is also described in other specifications, and this other specification has already been written by another user. If used, access to this specification is prohibited. In this way, it is possible to exclude even other specifications containing the same content data. This makes it possible to prevent simultaneous modification of multiple specifications containing the same content, to protect the specifications written in the specifications from inconsistencies, and to guarantee the validity of the written contents of the specifications.

[0018]

Embodiments Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the configuration of an information processing system according to the present invention.

In the information processing system of this embodiment, the user interactively develops software, and the display unit 1 displays specifications, block diagrams, etc. used for software development, and the screen of the display unit 1 an input unit 2 where the user inputs data while referring to the data input unit 2, a data processing unit 3 which performs data processing such as arithmetic processing and image processing based on the data input by the user, and an operation control program for the data processing unit 3. It is composed of a storage section 4 that stores the following information.

[0021] The storage unit 4 stores a related file 5 and an exclusive information file 6 having information related to the present invention. This related file 5 contains a specification name ID (Identifier) indicating each specification name (collection data identifier).
fier, identifier) 7 and a content data ID 8 indicating the content data name (identifier of data included in the aggregate data) described in each specification document are registered. for example,
The specification name ID “SDF (1)” includes “parts management” and “
Two content data "Delivery Management" are described, and the specification name ID "SFL (3)" contains the content data name "DS
R2103" is written. The exclusive information file 6 also includes a content data ID 9 indicating the name of each content data, an exclusive flag 10 indicating whether or not each content data is under exclusive control, and
A setter ID 11 indicating the user who performed exclusive control is registered. For example, the content data ID "Parts management" and "Delivery processing" have an exclusive flag of "0", indicating that exclusive control is not set, and the content data ID "DSR2103" indicates that exclusive control is not set.
” has an exclusive flag of “1” and a setter ID of “TARO(
12)" indicates that exclusive control has been set by the user.

[0022] The data processing unit 3 is a CPU (not shown).
(Central Processing Uni
a central processing control unit 12 that controls the operation of the entire information processing system based on the operation of the central processing unit (t, central processing unit); and
The user uses FDD (Flexible Disk D)
An exclusive control unit 14 that performs exclusive control of data access according to the present invention uses a related file 5 and an exclusive information file 6 for a tool 13 used via a drive unit, floppy disk device, etc. It is configured.

[0023]The exclusive control unit 14 according to the present invention includes a tool request receiving unit 15 that receives requests for access to specifications from the tool 13, and content data described in the specifications received by the tool request receiving unit 15. , related file 5
Exclusive information that searches the exclusive information file 6 based on the content data searched by the related search unit 16 and checks whether or not this content data is under exclusive control. As a result of the check by the search unit 17 and the exclusive information search unit 17, if the content data is under exclusive control, access sends a message to the tool 13 that exclusive processing has already been set for this specification. If the result of the check by the unacceptable message response unit 18 and the exclusive information search unit 17 is that no exclusive processing is set for any of the content data, the exclusive information file 6 is updated and exclusive information is added to these content data. An exclusive control completion message response that sends a message to the tool 13 that the exclusive information setting unit 19 has finished updating all content data subject to exclusive control in the exclusive information file 6. 20.

With this configuration, the information processing system of this embodiment can perform exclusive control over not only content data but also specifications in software development, and can verify the validity of the written contents of specifications. can be guaranteed.

That is, the tool request accepting unit 15 accepts a request for exclusive control from the tool 13 to a specification document using the user name ID and specification name ID making the request, for example, "SD
F(1)” is accepted. The related search unit 16 searches the related file 5 using this specification name ID "SDF (1)" as a search key, and searches for the content data ID described in this specification.
8, first obtain "parts management". The exclusive information search unit 17 searches the exclusive information file 6 using the content data ID 8 "parts management" described in this specification as a key, and sets the exclusive flag for the content data ID 9 "parts management". Whether or not it is set, and the setter ID1
1 is the same as the user ID requesting access to the specification "SDF(1)". In the exclusive information file 6, the exclusive flag 10 for the content data ID "parts management" is "0", and no exclusion flag is set for this content data ID "parts management". Here, the exclusive information setting unit 19 may set the exclusive flag of the exclusive flag 10 for "parts management" of the exclusive information file 6 to "1", but in order to improve processing efficiency, The exclusive flag setting process to the exclusive flag 10 by the information setting unit 19 is performed by setting exclusive flags and setter I for all content data in the specification.
Do this after checking D.

[0026] Similarly, the related search unit 16 searches the related files 5, and then selects the "delivery process" from the content data ID8 described in "SDF (1)" of the specification name ID7.
, and the exclusive information search unit 17 searches the exclusive information file 6 using the "delivery process" of the content data ID8 as a key. In this way, after acquiring the information that all the content data described in the specification "SDF (1)" is not under exclusive control, the exclusive information setting unit 19 sets the content data of the exclusive information file 6. Set the exclusive flag 10 for "Parts management" and "Delivery processing" of ID9 to "
1”. The exclusive control completion message response unit 20 responds to the tool 13 with a message such as "exclusive control settings have been completed for all content data described in the specification."

On the other hand, the request for exclusive control of the specification from the tool 13 is, for example,
” and the specification name ID “SFL (3)”, the content data ID 8 to be searched by the related search unit 16 is “DSR2103
”. Then, in the exclusive information file 6 searched by the exclusive information search unit 17, “DSR21
The exclusive flag 10 corresponding to "03" is set to "1", and the setter ID 11 that set this exclusive flag is "
TARO (12)". In this way, the setter ID 11 (“TARO (12)”) of the exclusive information file 6
) is the user ID “
JIRO (11)", the access prohibition message response unit 18 informs the tool 13 that "the content data described in the specification for which access was requested has already been set for exclusive processing by another user. It responds with a message such as "This is being done."

As described above, according to the information processing system of this embodiment, simultaneous modification of multiple specifications containing the same content can be prevented. Next, the processing operation of the information processing system of this embodiment according to the present invention will be explained using a flowchart.

FIG. 2 is a flowchart showing an embodiment of the processing operation of the information processing system shown in FIG. 1 according to the present invention.

In particular, it shows the operation of each part of the exclusive control unit 14 in FIG. 1. First, the tool request receiving unit 15 in FIG.
is the user ID requesting exclusive control over the specifications.
, the specification name ID is received, and this information is passed to the related search unit 16 in FIG. 1 (step 201). Related search section 1 in Figure 1
6 uses the received specification name ID as a search key to search for the content data ID described in this specification stored in the related file 5 (step 202), and sends the content data ID of the search result and the access request. The current user ID is passed to the exclusive information search unit 17 in FIG. 1 (step 203). The exclusive information search unit 17 in FIG.
Using as a search key, search for whether or not the exclusive flag 10 is set in the content data ID 9 stored in the exclusive information file 6 of FIG. 1, and the setter ID 11 that set the exclusive flag (step 204). From this search result (step 205), it is determined whether an exclusive flag is set to the content data ID (step 206).

[0031] If the exclusive flag is set,
It is determined whether the setter ID that set the exclusive flag and the user ID attempting to access are the same ID (step 207). The setting presence/absence information of the exclusive flag 10 in the exclusive information file 6 in FIG. 1 is set to "1" when exclusive control is performed, and "0" when exclusive control is not performed.
" is set. Hereinafter, the case of "1" under exclusive control will be abbreviated as "locked state", and the case of "0" that is not under exclusive control will be abbreviated as "locked state".
” is abbreviated as “no lock state.”

Now, the search result is a locked state,
In addition, if the setter ID who set the exclusive flag and the user ID who attempts to access are different, then
The access not allowed message response 307 indicates that the content data ID described in this specification is already locked and cannot be accessed by the tool 13 in FIG.
(step 208). Until all the content data IDs described in this specification are obtained, the setter I who set this exclusive flag will
If D and the user ID are the same, confirmation of the exclusive control setting state of the content data is repeatedly processed (step 209).

[0033] Once all content data IDs have been obtained,
The exclusive information set 308 in FIG. 1 updates the exclusive flag 10 of the content data ID 9 of the exclusive information file 6 in FIG. (Step 211). The process is repeated for all the content data described in the specification until the locked state is updated (step 212). When this process is completed, the exclusive control completion message response 309 in FIG. 1 sends a message to the tool 13 that the exclusive control has been completed (step 213).
.

In this way, according to the first embodiment, exclusive control can be applied to other specifications having at least one of the same content data, and the same Consistency of content data can be maintained.

[0035] In the above-described embodiment, when another specification that includes at least one piece of content data that is the same as the content data included in the specification,
Although exclusive control is performed, the present invention can also be applied to exclusive control of data that is in a dependent relationship with content data included in a specification. The dependent relationship here refers to a relationship in which, although the data are not the same, if the content data is changed, the consistency of the content is no longer established, and other content data must also be changed. This can be achieved by providing a dependent relationship file that defines the dependent relationship between content data, and a function to search for the dependent relationship based on this dependent relationship file and obtain content data in the dependent relationship. Exclusive control over content data of such a dependent relationship will be explained below.

FIG. 3 is a block diagram showing a second embodiment of the configuration of an information processing system according to the present invention.

The information processing system of this embodiment is an application of the information processing system shown in FIG. 1 to a system for recording and managing subordinate related information. and the exclusive control unit 14 includes a dependent related file 32 and this dependent related file 32.
, a dependent relation search section 31 that performs a search for , a newly provided storage section 33 , an exclusive control section 34 , and a data processing section 30 . The other components below are the same as those explained in FIG. 1, and to avoid redundant explanation,
Only the parts characteristic of the embodiment will be explained.

In the exclusive control unit 34, the related search unit 16
contains the content data ID which is the search result of related file 5.
A function is added to pass the information and the user ID making the access request to the dependent relation search unit 31. Then, the subordinate related search unit 31 receives the content data I from the related search unit 16.
Using D as a search key and the dependent related file 32,
A search is performed for the content data ID that is in a dependent relationship with the content data, and the search results are obtained. In order to distinguish between the content data ID described in the specification and the content data ID that is in a dependent relationship with the content data, the latter will be referred to as the dependency relationship data ID from now on.

In the storage unit 33, the dependent related file 3
2 is content data ID 35 described in the specification and dependency relationship data ID 36 that is in a dependent relationship with the content data.
This is a file that maintains the relationship with. The operation of the information processing system of the second embodiment will be described below based on the flowchart.

FIGS. 4 and 5 are flowcharts showing an embodiment of the processing operation of the information processing system shown in FIG. 3 according to the present invention.

[0041] Steps 201 to 20 in the figure
9 and steps 210 to 213 are exactly the same as the processing shown in FIG. The operation of the characteristic parts of this embodiment will be explained.

When the related search unit 16 and exclusive information search unit 17 in FIG. 3 complete the search process for all content data in the specifications based on the related file 5 and exclusive information file 6 in FIG. Step 20
9) The dependent relation search unit 31 in FIG. 3 receives the user ID making the access request to the specification and information on all the content data IDs described in this specification, and searches the content data IDs. As a search key, the dependent related file 32 in FIG.
The dependency relationship data ID 36 stored in the file ID 36 is searched (step 401). Then, the dependency relationship data ID of the search result
and passes the user ID making the access request to the specification to the exclusive information search unit 17 in FIG. 3 (step 402).
. The exclusive information search unit 17 in FIG.
Based on D, the exclusive information file 6 in FIG. 3 is searched (step 403), and exclusive information data is acquired (step 4).
04), determining whether or not the exclusive flag is set (step 4)
05), confirmation of exclusive flag setter ID (step 406)
) is performed on all the dependency relationship data related to the content data (step 407). If all of the dependency relationship data is not under exclusive control, an exclusive flag is set for all of the dependency relationship data and the process ends (steps 210 to 213).

In this way, according to the second embodiment, it is possible to perform exclusive control of data that is in a dependent relationship with the content data included in the specification. In other words, the content data of specifications generated in the design process such as software development are mutually related throughout the entire specification, and there are many expressions with different levels of detail. Accordingly, the consistency of mutually related content data is not destroyed.

Next, the information processing system of the present invention allows the user to select, for example, whether to perform exclusive control in units of conventional files or exclusive control in units of content data described in the specifications. You can also. In this case, this can be achieved by having a function that accepts requests for which exclusive control should be used and distributes them to the respective exclusive control processes. An information processing system that performs such processing operations will be described below.

FIG. 6 is a block diagram showing a third embodiment of the configuration of an information processing system according to the present invention.

The information processing system of this embodiment is an application of the information processing system shown in FIG. 1 to a system in which the user can select the unit of exclusive control. A data processing section 5 includes an exclusive control section 54 that includes a specification exclusive information search section 52, and a specification exclusive information set section 53 in the exclusive control section 14 of FIG.
0 and a specification exclusive information file 55 (set data exclusive information file) are newly provided in the storage section 56 in the storage section 4 of FIG. Hereinafter, other constituent parts are the same as those explained in FIG. 1, and only the parts characteristic of the third embodiment will be explained to avoid redundant explanation.

The specification exclusive information file 55 includes a specification name ID 57 and an exclusive flag 58 for this specification.
The ID 59 of the person who set this exclusion flag 58 is stored. Based on the identifier input by the user through the input unit 2, the exclusive format request receiving unit 51 determines whether the user's request is for conventional exclusive control on a per-file basis or for content data described in the specifications. It accepts requests for exclusive control on a unit basis, and switches the exclusive control processing method according to this request. Specification exclusive information search unit 52
searches the specification exclusive information file 55 using the specification name ID 57 as a search key, determines whether or not the exclusive flag 58 is set for this specification, and determines whether the exclusive flag 58 is set for this specification.
A check is made to see if the setter ID 59 that has been set to 8 is the same as the user ID that is requesting access to this specification. The specification exclusion information setting unit 53 sets the specification exclusion information file 55 to the specification when the exclusion flag is not set for the specification, or when the exclusion flag is set, person ID and
When the user ID making the specification access request is the same, the exclusive flag 58 of the specification exclusive information file 55
is set to "1", and the record of the setter ID 59 is updated. The operation of the information processing system of the third embodiment having such a configuration will be described below using a flowchart.

FIGS. 7 and 8 are flowcharts showing an embodiment of the processing operation of the information processing system shown in FIG. 6 according to the present invention.

Note that the processing in step 201 and steps 202 to 213 in the figure is exactly the same as the processing shown in FIG. will be omitted, and the operation of the characteristic parts of the information processing system in FIG. 6 will be explained.

When the tool request reception unit 15 in FIG. 6 receives the user ID and specification name ID that are requesting exclusive control over the specification (step 201), the tool request reception unit 15 receives these user ID and specification name ID. , the exclusive format request reception unit 51 in FIG.
pass it on to The exclusive format request accepting unit 51 in FIG. 6 accepts a user's request for exclusive control on a conventional file basis or exclusive control on a content data basis described in the specifications (step 601). ), according to this request,
The exclusive control processing method is switched (step 602). At this time, information on the user ID requesting access to the specification and the specification name ID is passed to the related search unit 16 in FIG. 6 or the specification exclusive information search unit 52 in FIG.

[0051] When the user's request for exclusive control is in units of content data described in the specifications, the processes after the related file search shown in FIG. 2 (steps 202 to 213) are performed.
is the same as On the other hand, when the user's request for exclusive control is in file units, the specification exclusive information search unit 52 in FIG. 6 uses the received specification name ID as a search key to store information stored in the specification exclusive information file 55 in FIG. Search for whether or not the exclusive flag 58 is set for the specified specification name ID 57 and the setter ID 59 that set this exclusive flag 58 (step 603), and from the information in the search results (step 604), search for this specification. It is determined whether an exclusive flag is set to the book title ID (step 605). If the exclusive flag is set, the setter ID who set this exclusive flag
It is determined whether or not the user IDs attempting to make access are the same ID (step 606). If the search result is a locked state and the setter ID that set this exclusive flag is different from the user ID that is trying to set a new exclusive flag, access is disabled as shown in Figure 6. The message response unit 18 sends a message to the tool 13 in FIG. 6 that this specification is already locked and cannot be accessed (step 208). on the other hand,
Even if the search result is a lock-free state or a lock state, if the setter ID and user ID are the same, the specification exclusive information set unit 53 in FIG. 6 sets the specification exclusive information file 55 in FIG. The exclusive flag 58 of the specification name ID 57 is updated to a locked state (step 607), and the setter ID that set the exclusive flag is updated (step 608). When these processes are completed, the exclusive control completion message response unit 20 in FIG. 6 sends a message to the tool 13 in FIG. 6 that exclusive control has been completed (step 213), and ends the process.

This embodiment is effective when creating specifications during a trial software design process. For example, when creating an alternative specification when the specifications cannot be determined in one way, or when creating the contents of a specification for private purposes,
Also, when you want to record the history of specifications in the design process, you can free yourself from the constraint that the content must be consistent with existing content data, and you can freely design and record specifications. can.

In this embodiment, the exclusive control selection by the user of the exclusive format request accepting unit 51 shown in FIG. 6 is not input from the user, but is made from the tool 13 shown in FIG. It is also possible to give information that exclusive control is applied to the described content data unit.

[0054] Furthermore, by combining the third embodiment and the first embodiment, specifications for all set data having updated data can be created based on the update of the exclusive information file in the first embodiment. It is also possible to set the exclusive flag of the exclusive information file to "1". This makes it possible to quickly obtain the result of the access determination process.

[0055] Next, in such an information processing system, it is also useful to provide a function that allows only reference to specifications that are under exclusive control. That is,
If a user has exclusive control over a specification for updating, it is possible to allow another user who attempts to access the specification to only view this specification. , the user is notified by a message that even if they edit, they cannot be recorded in a file, and the user can choose whether or not to obtain access to this specification as information only for reference. In this case, upon receiving the access denied message, the user will be notified of the message,
