First, assuming that the database 100 has the structure shown in FIG. 2, the search key header 102 has the values shown in (Table 1), the search key header 103 has the values shown in (Table 2), and the information element 110 has the (table It is assumed that the values shown in 3) are stored.

[0020]

[Table 1]

[0021]

[Table 2]

[0022]

[Table 3]

Further, the contents shown in (Table 4) are stored in the user database 301.

[0024]

[Table 4]

A user who wants to obtain the information stored in the database 100 first inputs his user ID from the ID input section 302. The authentication unit 303 uses the user ID stored in the user database 301 in advance and the I
The user ID input by the D input unit 302 is collated, and the group ID of the group to which the user belongs is acquired. For example, when the user ID “Nakamura” is input from the ID input unit 302, “group 1” is acquired as the group ID.

Next, the user inputs the search key added to the information to be acquired from the search key input unit 201, and instructs the operation instruction button 202 to perform the "acquisition process".

When the acquisition section 402 is instructed to perform the "acquisition process" from the operation instruction button 202, the acquisition section 402 requests the search section 401 to acquire the search key header of the operation target information. Upon receiving the request from the acquisition unit 402, the search unit 401 sequentially compares the search key input by the search key input unit 201 with the search key header stored in the search key table 101,
The search key header with the matching search key is acquired, and the acquisition unit 4
02 to provide. For example, when “questionnaire 1” is input as a search key in the search key input unit 201, the search key header 102 is acquired.

The acquisition unit 402 acquires the storage location of the first information element from the link information of the search key header acquired from the search unit 401, acquires the information element through the search unit 401, and adds it to the access right header of the acquired information element. It is determined whether or not the group ID stored in the included read access right includes the group ID acquired by the authentication unit 303. If the group ID is included, the data unit of the acquired information element is stored in the information processing unit 203. To do. If it is not included, it is considered that there is no access right, the link information of the acquired information element is referred to, the next information element is acquired, and the verification of the access right is repeated. If there is no access right to any information element, the information acquisition process fails.

For example, when the user ID is "Nakamura", the belonging group is "group 1", and this group ID
Is included in the read access right of the information element 110, the content of the data section 112 is stored in the information processing section 203, and the user can refer to the content. When the user ID is “Mitani”, the group ID is “group 2”, and this group ID is information element 1
The search key header 1 is not included in the read access right of 10.
No other information element is associated with 02, so acquisition of information fails.

As a result, a user having “Nakamura” or “Okauchi” as the user ID can obtain the data section 112 because the group ID is “group 1”, but a user having “Mitani” or “Mitsuda” can obtain the group ID. The data part 112 cannot be acquired because is “group 2”.

A user who wants to update the information stored in the database 100 first inputs his user ID from the ID input section 302. The authentication unit 303 uses the user ID stored in the user database 301 in advance and the I
The user ID input by the D input unit 302 is collated, and the group ID of the group to which the user belongs is acquired. For example, when the user ID “Nakamura” is input from the ID input unit 302, “group 1” is acquired as the group ID.

Next, the user inputs the search key added to the information to be updated from the search key input section 201, and instructs the operation instruction button 202 to perform the "update process".

When the update instruction is given from the operation instruction button 202, the update section 403 requests the search section 401 to acquire the search key header of the operation target information. Upon receiving the request from the update unit 403, the search unit 401 sequentially compares the search key input in the search key input unit 201 with the search key header stored in the search key table 101, and the search key headers in which the search keys match Is obtained and provided to the updating unit 403. For example, when “questionnaire 1” is input as a search key in the search key input unit 201, the search key header 102 is acquired.

The updating unit 403 acquires the storage location of the first information element from the link information of the search key header acquired from the searching unit 401, acquires the information element through the searching unit 401, and accesses the acquired access right of the information element. For the group IDs listed in the write access right included in the header, the group I acquired by the authentication unit 303
It is determined whether or not D is included, and if it is included, the content of the information processing unit 203 is stored in the data portion of the information element acquired earlier in the database 100 through the search unit 401. If it is not included, it is considered that there is no access right, the link information of the acquired information element is referred to, the next information element is acquired, and the verification of the access right is repeated. If there is no access right to any of the information elements, the information update process fails.

For example, when the user ID is "Nakamura", the group ID is "group 1".
Since D is included in the write access right of the information element 110, the contents of the information processing unit 203 are stored in the data unit 112, and the user can update the contents. When the user ID is "Mitani", the group ID is "group 2", and this group ID is information element 1
Since it is not included in the write access right of 10, the information update fails.

As a result, the user having the user ID "Nakamura" or "Okauchi" can update the data section 112 because the group ID is "group 1", but "Mitani"
Alternatively, the user having “Mitsuda” cannot update the data part 112 because the group ID is “group 2”.

A user who wants to stamp the information stored in the database 100 first inputs his user ID from the ID input section 302. The authentication unit 303 is a user ID stored in advance in the user database 301.
And the user ID input by the ID input unit 302 are collated, and the group ID of the group to which the user belongs is acquired. For example, when the user ID “Nakamura” is input from the ID input unit 302, “group 1” is acquired as the group ID.

Next, the user inputs the search key added to the information to be stamped from the search key input unit 201, and instructs the operation instruction button 202 to perform the "marking process".

When the "marking process" is instructed from the operation instruction button 202, the stamping unit 404 requests the search unit 401 to obtain the search key header of the operation target information. Upon receiving the request from the seal stamp unit 404, the search unit 401 sequentially compares the search key input by the search key input unit 301 with the search key header stored in the search key table 101,
The search key header with the matching search key is acquired, and the stamping unit 4
04 to provide. For example, when “questionnaire 1” is input as a search key in the search key input unit 201, the search key header 102 is acquired.

The stamping unit 404 sequentially refers to the stamping information contained in the acquired search key header, and the stamping state is "not yet executed".
Find what is. If the stamping information with the stamping status of "not performed" is not found, the stamping process fails because all stamping has been performed. If the stamp information with the stamp status of “not yet performed” is found, the user ID stored in the stamp user of the stamp information and the user I input by the ID input unit 302
D is compared, and if they match, it is assumed that the stamp processing authority is given, the corresponding stamping status is set to "executed", and if they do not match, the stamp processing authority is not given, and the stamping processing fails.

When it is determined that the user has the authority to perform the stamping process, the stamping unit 404 obtains the storage location of the first information element from the link information of the search key header obtained from the search unit 401, and the information element is retrieved through the search unit 401. Group I of all groups that get and have read access to it
Store D, erase the contents of the write access right, and store it in its original location in the database. In addition, the storage location in the database of the information element is stored in the link information of the acquired information element, the stamp information included in the search key header is referred to again in order, and next, the one whose stamp status is "not executed" is checked. look for. When the stamp information with the stamp status "unexecuted" is found, the read access right and the write access right of the acquired information element store the group ID of the group to which the user who presses the next stamp belongs, and a database as a new information element. To store. Also, the storage location of the newly stored information element is stored in the acquired link information of the search key header, and the corresponding search key header in the database is updated.

For example, when the user ID is "Nakamura" and "questionnaire 1" is specified as the search key to perform the stamping process, the search key header 102 is acquired. Since the stamped information 1 of the search key header 102 has a stamped state of “not performed” and the stamped user is “Nakamura”, it is determined that the user has the authority to perform the stamping process. Then, the information element 110 that is first linked to the search key header 102 is acquired. In the read access right of the acquired information element 110, "group 1" and "group 2" are stored as the group IDs of all groups, and the contents of the write access right are deleted and stored in the database 100 as the information element 110. To do. Further, the storage location of the information element 110 is stored in the acquired link information of the information element 110, the stamp information included in the search key header 102 is referred to again in order, and the next stamp state is the stamp information of “unexecuted”. Discover the stamp information 2. Since the stamped user of the stamped information 2 is “Mitani”, the group ID “group 2” of the group to which “Mitani” belongs is passed through the authentication unit 303 to the user database 30.
1 and stores it in the read access right and the write access right, and the database 1 as the new information element 140.
Stored in 00. Finally, the storage location of the information element 140 is stored in the link information of the search key header 102, and the stamping process is completed. As a result, the content of the database 100 has the structure shown in FIG. 6, the content of the search key header 102 is the value shown in (Table 5), the content of the information element 110 is the value shown in (Table 6), and the content of the information element 140 is ( (Table 7)
It becomes the value shown in.

[Table 7]

In this state, when the update process is executed with the user ID "Mitani" and the search key "Questionnaire 1", the search key header 102 is acquired, and the access right information 141 of the first information element 140 is obtained by tracing the link information. Is inspected. Since "group 2" to which "Mitani" belongs is stored in the write access right of the access right information 141, it is considered that there is an access right, and the contents stored in the information processing unit 203 are stored in the data unit 142. It is stored and the update process is performed.

In this state, the user ID is "Nakamura",
If you execute the acquisition process with the search key as "Questionnaire 1",
The search key header 102 is acquired, the access right information 141 of the first information element 140 is inspected by following the link information, and the group I of the group to which "Nakamura" belongs
Since D "group 1" is not stored in the read access right, the access right header 111 of the next information element 110 is checked by following the link information. Since “group 1” is stored in the access right header 111, it is considered that there is an access right, and the contents of the data section 112 are stored in the information processing section 203.

That is, in this state, when "Nakamura" and "Okauchi" belonging to the group of "Group 1" perform the information acquisition process for the search key "Questionnaire 1",
The data section 112, which is the data at the time when the stamp processing is performed by "Nakamura", can be acquired, and the update processing cannot be executed because the corresponding information element does not have the write access right. Also, "Mitani" and "Mitsuda" belonging to the "Group 2" group
When the information acquisition process is performed for the search key “questionnaire 1”, the data part 142 that is the data updated by “Mitani” can be acquired, and the update process is similarly performed for the data part 142. Can be carried out.

As described above, according to the present embodiment, with respect to the information before the stamping process, the access right to the acquisition process and the update process is given only to the user group to which the user who performs the stamping belongs next, and the stamping process is performed. For the processed information, the access right can be given to the acquisition processing for all groups.
