Abstract

PROBLEM TO BE SOLVED: To provide a menu information generator which quickly displays the same menu for every user from each client in a network environment. SOLUTION: When a user inputs log-in information from a client 1, a menu display request is transmitted from the client 1 to a server 2. In the server 2, a user discrimination part 21 checks log-in information. When it is correct, a menu generation flag in a user access right information file 3 is checked to discriminate whether menu generation is necessary or not; and if it is necessary, a user display menu generation part 24 generates a user display menu information file 6 based on user and group access keys in the file 3 and a group access right information file 4 and the access right of a hierachized menu in a menu structure information file 5 and transmits it to the client 1. In the client 1, a menu display expansion part 12 expands this data to menu display data and displays it on a display device 13.

In the figure, 1 is a client connected to a network such as a LAN, 2 is a server connected to the client 1 via the LAN, 3 is a user access connected to the server 2 and storing the access right of each user. Right information file, 4 is a group access right information file which is connected to the server 2 and stores the access right of the group,
5 is a menu structure information file connected to the server 2,
Reference numeral 6 is a user display menu information file connected to the server 2.

Next, the configuration of the client 1 will be described.
Reference numeral 11 is an input unit that accepts input of a login name and password from the user, 12 is a menu display expansion unit that expands the display information of the menu based on the user display menu information file 6, and 13 displays the output of the menu display expansion unit 12. Display device.

Next, the configuration of the server 2 will be described. Reference numeral 21 is a user identification unit that checks the validity of the login requested by the client 1, checks the access key corresponding to the menu to be displayed, and determines whether or not the menu information to be displayed has been created, and 22 is a user and group. An access right management unit that manages access right information about a menu structure 23, a menu structure management unit 23 that manages menu structure information 24,
Is a user display menu creation unit that creates a menu for each user based on the access key acquired from the user access right information file.

In order to display the menu, the server 2 has a user access right information file 3, a group access right information file 4, a menu structure information file 5, and a user display menu information file 6.

As shown in FIG. 2, the user access right information file 3 stores items of login name and password, belonging group name, access key, menu creation flag, and user display menu information file name. FIG.
The access key of the user indicated by a decimal number is managed by bits. That is, access key = "1" is bit 0, access key = "2" is bit 1, access key = "4".
Is bit 2, access key = “8” is bit 3, access key = “16” is bit 4, access key = “32”
Means bit 5

The group access right information file 4
Holds the group name and access key items as shown in FIG. The access key of the group represented by a decimal number in FIG. 3 is also managed by bits. That is, the access key
= “64” means bit 6, access key = “128” means bit 7, access key = “256” means bit 8, access key = “512” means bit 9.

As shown in FIG. 4, the menu structure information file 5 includes the menu name, the record number of the parent menu if there is a parent menu that is hierarchical and the record number of the child menu if there is a child menu, and the child menu. If does not exist, it stores the name of the executable file and each item of access right that specifies the user who can display the menu.

The user display menu information file 6
Is a file that exists for each logged-in user and stores menu information to be displayed. As shown in FIG. 5, data to be displayed is selected and stored from the menu data of FIG. The menu data of the user display menu information file 6 is transmitted to the logged-in client 1 and is displayed by the client 1 on the display device 13 as shown in FIG.

7 and 8 are flowcharts showing the flow of the operation of the menu information creating apparatus according to the present invention.

Next, the operation of the menu information creating apparatus shown in FIG. 1 will be described with reference to the flowcharts shown in FIGS. 2 to 6 and 7 to 8. Here, for example, the login name will be described as << A >>. The user inputs the login name << A >> and the password << xxx >> from the input unit 11 (eg keyboard) of the client 1 (step S1).
When requesting a connection to the network, the client 1 sends the login name and password to the server 2 (step S2). The user identification unit 21 of the server 2 searches the user access right information file 3 shown in FIG. 2 based on the login name and password (step S3) received from the client 1 to determine whether or not the corresponding record exists. Is determined (step S4).

If there is no corresponding record, it is regarded as an access by an unauthorized user and an error is transmitted to the client 1 (step S6). If the corresponding record exists, the access key of the record is acquired (step S5), and it is determined whether the menu creation flag is 1 (step S7). If the menu creation flag is 1, it means that there is a created user display menu 6 corresponding to the user display menu information file name. Therefore, referring to the access right information file 3 and the menu structure information file 5, etc. The data of the created user display menu information file 6 is directly transmitted to the client 1 without creating the display menu information file 6 (step S8).

In step S7, when the user display menu information file 6 does not exist, or when the menu creation flag is 0, the user display menu information file 6 is created. And if there is a group name (step S
9) Get the group name.

In this example, as shown in FIG. 2, by reading the record with the login name << A >>, "1" is acquired as the user's access key, and the menu creation flag is "0", so the group name " MMM ”is acquired.

Next, based on this group name "MMM", the corresponding record is read from the group access right information file 4 shown in FIG. 3 and the access key of the group is acquired (step S10). In this example, "128" is acquired as the group access key.

Next, the access key of the user and the access key of the group are ORed to obtain the access key.
(Step S11). For example, since the access key of the user << A >> is the logical sum of "1" and "128", "12"
9 "(FIGS. 2 and 3).

Next, the user display menu creating section 24
Create user display menu information (step S1)
2). In this case, first, the top record of the menu structure information file 5 shown in FIG. 4 is read (step S13). For example, in this example, the first record is the most parent menu information.

Next, the record indicated by the child menu record number is read from the menu structure information file 5 to obtain the access right. This access right is ANDed with the acquired access key (step S14), and it is checked whether the bit corresponding to the access key is true (step S15). If true, the user display menu information file User display menu information file 6 to create 6
If there is an execution path, the menu name is described in (step S16), and the process jumps to step S16. If the bit corresponding to the access key is false, no processing is performed and the process jumps to step S16.

In the case of hierarchization, the corresponding record is read up to the point where NULL is written in the child menu record number, the menu name and execution path are obtained, and the user display menu information file 6 is described. (Step S17). Even when the child record number of the first record of the menu structure information file 5 is plural, the above processing is performed similarly (step S18).

For example, the creation of the user display menu information file 6 for the user << A >> will be described. In FIG. 4, record numbers 2, 3, 4, 5, 6, and 7, that is, menu 1, menu 2, menu 3, program A, program B, and program C exist as child menus of the main menu. Since the access key of the user << A >> is "129", as a result of the logical product of the access right and the access key, the bit corresponding to the access key becomes true is the menu 1 of the above menus.
Menu 2, program A and program B.

Next, as a child menu of menu 1, menu 11, menu 12, menu 13, program X
And the program Y exists, but the bit corresponding to the access key becomes true as a result of the logical product of the access key of the user << A >> and the access right, the menu 11, the menu 12, the program X, and the program Y are Become. Similarly, if the child menu record number is NULL, the user display menu information file 6 shown in FIG. 5 is created.

In creating the user display menu information file 6, if the record indicated by the child menu record number does not exist in the menu structure information file 5, error information is transmitted to the client.

When the creation is completed, the data of the created user menu information file 6 is transmitted to the client,
Set the menu creation flag of the corresponding record in the user access right information file to "1" (indicating creation)
(Step S19).

The client 1 is based on the user display menu information file 6 transmitted from the server 2 as shown in FIG.
Create a menu in the menu display expansion unit 12 shown in,
The menu shown in FIG. 6 is displayed on the display device 13 (step S20).

As described above, when the menu creation flag is 1, the user display menu information file 6 is directly copied to the client 1 without referring to the information file relating to the menu.
Since it is transmitted to, the menu display can be performed quickly.

Further, by adopting the method of transmitting from the server 2 to the client 1, the administrator can store the menu data and programs in the server 2 in a lump and send them to the client 1 when necessary. Since it is sufficient, each user does not need to store the menu data and the program in each client 1.

Next, a user access key and a group access key will be described. As described above, the logical sum of the access key of the user and the access key of the group becomes the access key. However, if the user belongs to a certain group, the access key of the user does not need to be specified. In that case, The access key of the group becomes the access key.

Therefore, even if the number of users increases, if the management is performed on a group basis, the management will not be complicated and the user management can be performed efficiently.

For example, previously user A has group 1,
It is assumed that the user B belongs to the group 2 and the user C belongs to the group 3, but that all three users belong to the group 3 due to the organizational reorganization. In the case of management on an individual basis, the access right of each record of the menu structure information file 5 must be changed for three users. On the other hand, in group-based management, it is only necessary to change the group to which the three users belong to the user access right information file 3. The user can also belong to a plurality of groups, and the access key in that case can be obtained by the logical sum of the access keys of the plurality of groups and the user's access key.

On the other hand, when the administrator instructs registration, modification, and deletion of users and groups by a terminal (not shown) on the server, the access right management unit 22 on the server causes the user access right information file 3 and the group access right. The contents of the information file 4 are rewritten according to the instruction. Further, in the case of registration or change, the menu creation flag of the user access right information file 3 is initialized to 0 (meaning that a new display menu information file needs to be created).
The menu structure management unit 23 on the server 2 rewrites the menu structure information file 5 associated with the registration, change, and deletion of users and groups.

Therefore, since the user cannot arbitrarily add or change the menu from the client, the management becomes easy.

In the case of registering or changing a user or a group, the access right of the menu structure information file 5 is updated according to the instruction of the administrator. When deleting a user or a group, the access right to the deleted user or group in each record of the menu structure information file 5 is cleared. When the menu registration, change, or deletion is instructed, the menu structure management unit updates the access right information of the menu structure information file 5, and the access right management unit sets the menu creation flag of the user access right information file 3. Initialize to 0.

[0048]

As described above, according to the present invention, the server is provided with the user access right information file storing the login information for each user and the information for specifying the menu to be displayed, and the client is the login for the user. Since the input means for accepting the input of the name and password and transmitting to the server, and the menu expansion display means for receiving the user display menu information from the server and expanding and displaying the menu are used by each user for the server. By storing the menu data and programs, the user can display the menu for each user without storing the data and programs used by each user in the computer of each client. The same menu can be displayed from any client, which has the effect of improving workability.

Further, according to the present invention, the menu structure management means changes the user menu information file and then transmits the user menu information file to the client, or directly changes the user menu information file to the client without changing the user menu information file. Since it is determined whether to send to the client, the menu display can be performed quickly by directly sending the created user menu information file to the client unless the menu structure is changed, so that the operability is improved.

Further, according to the present invention, the user access right information file, the user display menu information file, the user display menu creating means, and the menu display expanding means provided in the client are provided in accordance with the user's right. Since the menu is displayed on the client by the user, it is possible to prevent the user from arbitrarily changing the menu data and the program on the server, and it is possible to easily perform the menu management.

Further, according to the present invention, since the menu to be displayed in the group access right information file provided in the server is set for each group in which a plurality of users are combined into one, user management is performed even if the number of users increases. Has an effect that it can be easily performed without being complicated.
