To do. The input data is subjected to journal processing and the like in accordance with predetermined accounting rules, and various form data such as a journal diary, a general ledger, a trial balance, and an income statement are generated. For example, payment processing by sales, withdrawal processing by spending expenses, transfer processing by salary payment, etc. that occur daily in various departments are sequentially input from the user terminal of each department connected to the network, and the data processing means The processing of these input data is executed according to a preset program to generate various book table data. Furthermore, it performs closing processing and settlement processing of accounting processing for each predetermined accounting period such as monthly or yearly, and outputs various forms, summary tables, etc.

【0005】

These accounting data are stored in the database, but if all networked users are allowed to access, write, correct, etc. all the data files in the database, the data protection will be incomplete. Furthermore, accounting processing data often includes data that should be kept confidential to general users, such as information specific to the head office or branch office of a company, or management data of the accounting department, and general users to these confidential data. It is necessary to have a configuration that prohibits or restricts access to.

It has an accessible configuration.

【0020】

FIG. 2 shows an example of a system configuration in which the data access control device and the data access control method of the present invention are applied as an accounting system. The example shown in FIG. 2 is a network-type accounting system in which the input / output devices 101, 102, 103, the application server 104, and the database server 105 are connected via the network 106.

【0021】

The data access control device and the data access control method of the present invention are applicable not only to accounting systems but also to various database systems. Basically, it is applicable as long as it has a database configuration that can be accessed by multiple users connected by the network shown in Fig. 1, and various data access such as document management database and personnel information management database. It can be applied in the control device. Hereinafter, an example applied to the network-type accounting system shown in FIG. 2 will be described as a specific example of the data access control device and the data access control method of the present invention.

【0022】

The user terminals 11, 12, and 13 in FIG. 1 correspond to the input / output devices 101, 102, 103 in FIG. 2, and the access management server in FIG. 1 is the server 1051 in the database server 105 in FIG. 2 or the server 1041 in the application server 104. , 1042, and the information file database 50, user master database 51, and menu master database 52 in FIG. 1 correspond to the database 1052 in FIG.

【0023】

Hereinafter, the details of the data access control device and the data access control method of the present invention will be described by taking the network-type accounting system shown in FIG. 2 as an example. The input / output devices 101, 102, 103 are user terminal devices that use the accounting processing system, and the user inputs predetermined accounting data. For example, input accounting data generated at a business establishment, department, individual, etc. where each input / output device is arranged, such as input of a deposit slip related to sales and input of a withdrawal slip due to transportation expenses. Each of the input / output devices 101, 102, and 103 is a device assigned to a predetermined unit such as each business establishment unit, each department unit, or a user unit, and the accounting processing data generated in each assigned range is generated. Entered. The input / output devices 101, 102, 103 are described on behalf of the input / output device 103, but have a GUI function, and can output various data input screens and data display screens on the display as described later, and are displayed. You can enter accounting data on the screen.

【0024】

These input / output devices 101, 102, 103 are connected to the application server 104 and the database server 105 via the network 106.

【0025】

The application server 104 has servers 1041 and 1042 configured by, for example, a PC server as hardware, and executes various accounting processes according to the application programs in the servers 1041 and 1042. The database server 105 has a server 1051 and a database 1052. The server 1051 is composed of, for example, a UNIX machine or a PC server. The database 1052 stores the data input by the input / output devices 101, 102, 103, and the data processed by the application server 104 and the database server 105. The database 1052 further stores a user master table that stores user information and a menu master table that stores file information, which will be described in detail later.

【0026】

The application server 104 and the database server 105 execute various accounting processes such as input data processing, that is, journalizing processing of each input data, recording in each accounting book, and posting processing in the general ledger. The application server 104 mainly executes the processing according to each application program, and the database server 105 mainly executes the batch processing of the processing data by the application server 104, for example, the batch processing of the data on a daily basis.

【0027】

In order for the users of the input / output devices 101, 102, 103 to access the data files stored in the database 1052, the user ID and password unique to the user are entered in the input / output devices that execute the access. The login screen is shown in Fig. 3. As shown in FIG. 3, the user inputs the user ID and the setting password given to each user in advance on the screen.

【0028】

These entered user IDs and passwords are transferred over the network 106 to a server that performs access control. In Figure 2, server 1051 is assumed to be the server that performs access control. The server 1051 receives the user ID and input password from the user over the network.

【0029】

The server 1051 that receives the user ID and the input password from the user executes the determination of the user based on the user master table shown in FIG. 4 stored in the database 1052. As shown in FIG. 4, the user master table is a table that defines identification information, access authority, etc. of individual users. Company code, user ID, use start, end date, user name, user password, etc. are set as input information for each user. Based on these table information, matching with the user input ID and password is executed.

【0030】

Furthermore, in the user master table shown in Fig. 4, in items 8 to 11 such as "8. Temporary tightening period input possible classification" and "9. Input system authority classification", input, inquiry, and registration for the period or data file , A field for determining whether or not to modify is provided, and a predetermined value is input for each user. Further, item 12 is provided with a field indicating a menu ID. This menu ID is an ID indicating a hierarchical data menu of a plurality of data files that can be accessed by individual users, and will be described in detail later.

【0031】

Figure 5 shows an example of the data generated according to the user master table. As shown in FIG. 5, the data of each item in the user master table is set for each user, and is stored in the database 1052 in the network accounting processing system of FIG. In the system configuration example of FIG. 1, the user master table storing user data is stored in the user master database 51.

【0032】

In the example of the network-type accounting system shown in FIG. 2, the database 1052 further holds a menu master table. Figure 6 shows the data contents of the menu master table. The menu master table is a table that defines the unique information of each data file of a plurality of data files held in the database. In the example of the accounting processing system shown in FIG. 2, a plurality of accounting data held in the database 1052. It is organized as a table that defines the unique information corresponding to each accounting data file in the file.

【0033】

FIG. 6 is a diagram for explaining the data contents of the menu master table, and FIG. 7 is a diagram showing an example of sample data of the menu master table. FIG. 8 is a diagram showing an example of displaying a hierarchical data structure of a plurality of data files stored in the database 1052, that is, a hierarchically structured data structure stored in the database 1052.

【0034】

As can be seen from FIG. 6, the menu master table is set with individual data file specific information of a plurality of data files stored in the database 1052. For example, unique information corresponding to each data file such as a company code, a menu ID, and a menu item is set as an input item. The fields (items) shown in FIG. 6 indicate typical fields, and various fields other than the fields shown in FIG. 6 are set in the actual table.

【0035】

The menu master table of FIG. 6 will be described with reference to FIGS. 7 and 8 with actual examples. As shown in Fig. 8, the multiple data files stored in the database 1052 are hierarchically structured. FIG. 8 is a hierarchical structure data menu in which the name of the data file stored in the database 1052 is used as the data file identifier and the data file structure in the database 1052 is expressed in a hierarchical structure. In FIG. 8, for example, there are five data files under the file "general account": the files "balance inquiry", "organization input", "consumption tax", "others", and "source input". In addition, there are three files under the file "Balance Inquiry": the files "Account Ledger Inquiry", "Holding Ledger Inquiry", and "Journal Inquiry".

【0036】

Each item of the menu master table is set for each of these individual data files. Figure 7 shows an example of sample data for the menu master table. Similar to FIG. 6, the items shown in FIG. 7 show typical items, and various items other than the items shown in FIG. 7 are set in the actual table.

【0037】

As can be understood from FIG. 7, for example, in the data file whose menu display name is "Balance Inquiry", the menu ID is "ACM0000", the menu item is "1100", the parent item is "1000", and the menu division is "". 1 "is set. Furthermore, "ACM0000" is set as the menu ID, "1101" is set as the menu item, "1100" is set as the parent item, and "2" is set as the menu category in "Balance ledger inquiry" which is a lower file of "Balance inquiry". .. Note that the sample data example in FIG. 7 is simply described, and not all of the items shown in FIG. 6 are described.

【0038】

In FIGS. 6 and 7, the menu item ID is an identifier unique to each data file, and is an identifier uniquely assigned to each of all the data files forming the hierarchical structure of the hierarchical structure data menu shown in FIG. is there. The "parent item ID" indicates the "menu item ID" of the data file that is higher in the hierarchical structure shown in FIG. For example, the upper file of the file "Balance Ledger Inquiry" is "Balance Inquiry", and the "Menu Item ID" of "Balance Inquiry" is "1100", so the "Parent Item ID" of the file "Balance Ledger Inquiry" is "Parent Item ID". 1100 ". The "menu division" is used as an identifier that distinguishes between a data file in which a program should be started and a submenu in which a unique program does not need to be started, as described in FIG.

【0039】

The "menu ID" will be described. The menu ID is, for example, an identifier indicating the hierarchical structure data menu structure shown in FIG. In Fig. 8, "Plenary rights menu" is written at the top. This indicates that all accessible data in the database is shown as a hierarchical structure. The identifier of the hierarchical structure data structure corresponding to this plenipotentiary menu is, for example, menu ID: ACM0000.

【0040】

FIG. 9 shows a hierarchical structure data menu having a structure different from that of the hierarchical structure data menu shown in FIG. For example, the source input file, which is a subordinate file of the file general account shown in FIG. 8, is not shown in FIG. For example, the identifier of the hierarchical structure data menu structure shown in FIG. 9 is menu ID: ACM0001.

【0041】

Further, FIG. 10 shows a hierarchical structure data menu structure having a structure different from the hierarchical structure shown in FIGS. 8 and 9. For example, each file of "organization input", "consumption tax", "others", and "source input", which are subordinate files of the file "general account" shown in FIG. 8, is not shown in FIG. The identifier of the hierarchical data menu structure shown in FIG. 10 is defined as menu ID: ACM0002. FIG. 11 is similar to the hierarchical data menu structure shown in FIG. 10, and is shown by expanding the file Employee Management.

【0042】

Returning to FIG. 7, the correspondence with FIGS. 8 to 10 will be described. In FIG. 7, "ACM0000", "ACM0001", or "ACM0002" is set in the item "Menu ID" column. These indicate which menu ID is specified for each data file to be displayed as a hierarchical structure as shown in FIGS. 8 to 10.

【0043】

As shown in FIGS. 4 and 5, the item menu ID is set for each user. That is, the menu ID is uniquely determined based on the user ID of each user. For example, in the sample example shown in Fig. 5, Mr. Sato with the user ID "ABCAB" has ACM0000 set as the menu ID, and is composed of a data file with the menu ID "ACM0000" set in the menu master sample shown in Fig. 7. The hierarchical data menu is displayed. This is the plenipotentiary menu shown in FIG.

【0044】

Mr. Sato of the user ID "ABCAB" uses any of the input / output devices 101 to 103 shown in Fig. 2 to enter the user ID and user password and send them to the database server 1051 so that the database server 1051 becomes a user. The ID and the user password are identified, the user is confirmed using the user master table described in FIGS. 4 and 5, and the menu ID set in the user master table is determined.

【0045】

Further, the database server 1051 extracts a data file having the same menu ID as the discriminated menu ID from the menu master table described in FIGS. 6 and 7 based on the discriminated menu ID, and the extracted data file is used, for example, in the figure. Generate the hierarchical structure data menu shown in 8 ~ 10. These hierarchical data menus are generated based on the menu display name, parent item data, etc. set in the menu master table.

【0046】

For example, the hierarchical data menu shown in FIGS. 8 to 10 shows the data file name of each data file, the icon of each data file, the connection indicating the upper and lower file relations, and the existence of the lower file in the file. It is composed of + "symbols and symbols such as"-"indicating that there are no subordinate files in the file, but the information for generating these hierarchical structure data menus is basically obtained from the menu master table.

【0047】

In the above example, the database server 1051 selects a data file from the menu master table based on the menu ID and generates a hierarchical structure data menu based on the selected data file. However, a plurality of menu IDs are used in advance. A plurality of hierarchical structure data menus corresponding to the above may be registered in an independent hierarchical structure data menu table. With such a configuration, based on the menu ID sent from the user and identified by the user master table, the hierarchical data menu corresponding to the identification menu ID is immediately selected from the hierarchical data menu table of the user. It can be displayed on the input / output device. Therefore, it is possible to omit the step of searching the menu master table and generating the hierarchical structure data menu based on the search result.

【0048】

When the user receives, for example, the hierarchical structure data menu display shown in FIG. 8 in the input / output devices 101 to 103, the user determines the file to be opened from the displayed hierarchical structure data menu based on the hierarchical structure data menu shown in FIG. The file can be opened by specifying the pointing device of, for example, by clicking the mouse. Note that writing, deleting, etc. of data in each file is further set by input authority, inquiry authority, etc. as shown in FIGS. 4 and 5, and processing is controlled according to the set data.

【0049】

Returning to FIGS. 4 to 6, various authority control configurations such as input authority will be described. Fields 8 to 11 of the user master table in FIG. 4 are fields for setting various privileges corresponding to individual users. For example, "9. Input authority classification" is configured to set whether to input in company-wide units, accounting units, and department units, as described in the details column, and "10. Inquiry authority classification". "Is configured to set whether or not to make inquiries on a company-wide basis, accounting unit, or departmental basis.

【0050】

Field 7 "Startup permission check classification" of the menu master table in Fig. 6 is a field in which the start conditions of each data file are set corresponding to the various permissions set in fields 8 to 11 of the user master table in Fig. 4 above. is there. The details are as described in the "Details" column of FIG. 6. For example, if "N" is set in the field 7 of the menu master table of FIG. 6, the field "9: NKENKNBN" of the user master table is set. If ": Input system authority classification" is blank, this data file will not be started.

【0051】

For example, "9: NKEKNBN: Input system authority classification" is set in the menu master table corresponding to each of all the data files displayed in the hierarchical structure data menu shown in Fig. 8, and corresponds to each user. It is configured to allow input restrictions such as registration, modification, and deletion, and inquiry restrictions.

【0052】

For example, Mr. Suzuki of the user ID "KLMKN" shown in FIG. 5 has "ACM0001" set as the menu ID, and is composed of a data file in which the menu ID "ACM0001" is set in the menu master sample of FIG. The hierarchical data menu is displayed. This is menu 001 shown in FIG.

【0053】

Mr. Tanaka of the user ID "PQRFD" shown in FIG. 5 has "ACM0002" set as the menu ID, and is composed of data files in which "ACM0002" is set as the menu ID in the menu master sample of FIG. The structure data menu is displayed. This is menu 002 shown in FIG.

【0054】

When opening the required files from each displayed hierarchical structure data menu and executing data inquiry, data entry, data registration, etc., input each file set in the user master table and menu master table as described above. Whether or not processing is possible is determined based on various permissions such as permissions, and the user can perform processing within the permitted permissions.

【0055】

As described above, since the data access control device of the present invention is associated with the menu ID in which the hierarchical structure data menu to be displayed corresponding to each user is set, the user identification based on the user ID or the like is executed once. Then, all the files that the user can access can be displayed on the terminal used by the user as a hierarchically structured data menu, and the access permission processing for each data file can be performed as in the conventional database system. There is no need to execute it, complicated processing is alleviated, and processing time can be shortened. The user can also list the data structures available to the user, which helps the user understand the database structure and facilitates the use of data files. Further, for a confidential data file, not only the file name but also the existence itself in the database is not shown to the user who does not have the access right, so that the protection of confidentiality can be strengthened.

【0056】

12 and 13 show a setting screen for setting individual user information in the user master table in the data access control device of the present invention. FIG. 12 shows a basic information input screen for each user, and FIG. 13 shows a security information input screen.

【0057】

On the setting screen shown in FIG. 12, the company name, user ID, start and end date of use, user name, and department to which the user belongs are registered as basic user information. Regarding the password, each user executes communication with the database management server at an appropriate timing, inputs the password together with the user ID, and the password is registered and changed.

【0058】

On the security information input screen of FIG. 13, a menu ID that determines the hierarchical structure of accessible data files is set, and data entry, inquiry, and other privileges for accessible files are set. The data set in FIGS. 12 and 13 are registered in the user master table described in FIGS. 4 and 5.

【0059】

In the system configuration example of the data access control device shown in FIG. 1, the user information set in FIGS. 12 and 13 is registered in the user master database 51. When the access management server 30 receives the user ID and password set from the user terminals 11 to 13 via the network 20, the data in which the corresponding user ID is registered is extracted from the user master database 51 and the corresponding menu ID is extracted. , The menu master table is searched from the menu master database 52 based on the extracted menu ID, the data file having the corresponding menu ID is extracted, the hierarchical structure data menu is generated, and the data file is sent to the user terminal in which the access request is made.

【0060】

The present invention has been described in detail with reference to the specific examples. However, it is self-evident that a person skilled in the art can modify or substitute the embodiment without departing from the gist of the present invention. That is, the present invention has been disclosed in the form of an example, and should not be construed in a limited manner. In order to judge the gist of the present invention, the column of claims described at the beginning should be taken into consideration.

【0061】

[Effect of the invention]

As described above, according to the data access control device and the data access control method of the present invention, the hierarchical structure data menu to be displayed for each user is set according to the user ID unique to the user. Therefore, by identifying the user ID, it is possible to present the entire accessible data range to the user as a hierarchical structure data menu, which eliminates the need for access approval / disapproval processing for each file and shortens the processing time.

【0062】

Further, according to the data access control device and the data access control method of the present invention, the data files that can be used by the user can be listed as a hierarchical structure at the start of access, which helps the user to understand the database configuration and uses the data files. Simplification is achieved. Further, for a confidential data file, not only the file name but also the existence itself in the database is not shown to the user who does not have the access right, so that the protection of confidentiality can be strengthened.
