DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input / output device for inputting / outputting data from / to a database for maintaining the database, and more particularly to an item input system for inputting a plurality of items. The term “item” here means that, assuming a database relating to personnel management of a company, for example, “name”, “post”, “age”, “number of days off” and the like shown in FIG. 7 are each one item. To tell.

[0002]

2. Description of the Related Art In some of these items, a selection value is determined. For example, the item name "post" shown in FIG.
So, there are three choices: "President", "Senior Managing", "Manager" ...
Are predetermined and registered in, for example, the selection value data file 8 in FIG. 1 and when the item "post" is input, the selection value is displayed in the selection value display means 3 (FIG. 1) as shown in FIG. When the item "post" is input using the interactive input device, the input operation of the input operator is facilitated.

In some items, when an input operator makes an erroneous input, the input is checked and an error signal is displayed. For example, the item “number of days off” shown in FIG.
Must be 0 ≦ (number of days off) ≦ 50, and when an input operator enters a number outside this range, the device checks this and outputs an error signal. Have been.

[0004]

In the conventional data input / output device as described above, these selection values and check values are described in a program body or a simple language body, and it is necessary to change these values. When this occurs, there is a problem in that it cannot be easily changed by the input operator.

For example, the "data processing method" disclosed in Japanese Patent Laid-Open No. Hei 4-236662 is an invention which should be regarded as one of the prior arts of the present invention.

According to the present invention, according to the present invention, the system designer defines a selection item to be selected at the time of execution in an item group by an item name, and at the time of execution, the operator defines and displays this item. By directly instructing the required item name from among the selected item names, the selection process can be executed. "The operator cannot change the selected value. After the check value is also determined by the system designer, the check is usually performed by a method unknown to the operator.

That is, in the conventional item input method, when a selection value or a check value corresponding to an input item is changed, a business program or a simple language must be corrected for the change, and the program is compiled. Or reevaluation work. Also, when checking the input items, the operator does not know the check value,
The operator needs to confirm this with a manual or the like. The present invention has been made to solve such a problem.

[0007]

According to a data input / output device according to the present invention, a selection value is registered in a selection value data file, and a check value is registered in a check value data file. Allows the operator who updates the data of the item to display the selected value or check value corresponding to the item to be entered, and to freely update the contents of the selected value data file and the contents of the check value data file when necessary. did. In other words, updating the selection value (add /
By adding a selection value registration unit for performing (correction / deletion) and a check value registration unit for updating the check value, the operator who updates the data in the database can select the selection value,
Check value can be updated freely.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram functionally showing one embodiment of the present invention, in which a selection value registration means 1, a check value registration means 2,
The selection value display unit 3, the check value display unit 4, the item input unit 5, the input value check unit 6, and the control unit 7 are configured by computer program control. The selection value registered by the selection value registration unit 1 is The item name corresponding to the selected value is stored in the selected value data file 8 as a pointer, and the check value registered by the check value registering means 2 is stored in the check value data file 9 using the item name corresponding to the check value as a pointer. Is done.

The business data file 10 shown in FIG. 1 is a file storing a database to be updated. The business data file 10 is updated by the item input means 5. Each block shown in FIG. 1 is a block classified according to a function. For example, the item input means 5 is usually constituted by an interactive input means. Both the means 1 and the check value registration means 2 can be used as they are. Also,
This interactive input means has a display device such as a cathode ray tube as an interface for the operator, and this display device can be used as the selection value display means 3 and the check value display means 4 as they are.

Hereinafter, the operation of the apparatus shown in FIG. 1 will be described. 2 is a flowchart for explaining the operation of the apparatus shown in FIG. 1, FIG. 3 is an explanatory diagram showing an example of selection value data, FIG. 4 is an explanatory diagram showing an example of check value data, FIG.
6 is an explanatory diagram showing a display example of the selection value display means 3, FIG. 6 is an explanatory diagram showing a display example of the check value display means 4, and FIG. 7 is an explanatory diagram showing an example of a part of the business data file 10. In FIG. 2, S0 to S18 indicate each program step of the data processing.

In S2, S3, S11 and S16, an inquiry (input request) is made to the operator via the display device.
When the operator inputs a reply of YES or NO through the key, the program branches. When an input item is determined in S1, an inquiry in S2 is displayed for the determined input item. If the determined input item is "name", the data type is character and the number of digits is 10 from FIG. 3, there is no selection value or check value, and this is well known by the input operator. Therefore, NO is input in S2 and S3, the process proceeds to S4, and the "name" is input using a character of 10 digits or less from the keyboard. Data file 10
Is stored in

Next, the input item determined in S1 is "post".
If the answer is YES in response to the inquiry in S2, the program proceeds to S10, and the selection values stored in the selection value data file 8 corresponding to the item "post" are displayed as shown in FIG. You. If the displayed selection value is acceptable, NO is input for S11,
The program proceeds to S14, and an item is input. In this case, instead of inputting "management" from the keyboard, a numerical value 2 of the selection value may be input. Further, it is also possible to design so that the input key is pressed by setting the cursor on the selection value display means 3 to "2.

If there is no "management" in the "post" selection value displayed as shown in FIG. 5 and it is present in the actual post, and it is necessary to add the selection value, YES is returned in S11. Then, in S12, "Management" is added to the selection value 3 from the keyboard, the selection value of "Manager" is corrected to 4, and the selection values below "Manager" are respectively corrected. If the content is updated, this updated value
10, the item is input by the selected value in accordance with the updated display (S10-S11 to S10).
14).

At the time of system initialization, the contents of the selected value data file 8 may be blank. For the "items" that the input operator deems more convenient to input the selected value in S14 than to input from the keyboard in S4, "YES" is input in S2 and S11 for the "item", and the contents of the sequentially selected value data file 8 Can be satisfied.
On the other hand, the contents of the check value data file 9 need to be input almost correctly at the time of system initialization. Otherwise, the result of the determination in S5 is NO, and an input error is not checked. Writing to the selection value data file 8 and the check value data file 9 at the time of system initialization may be performed by a person other than the input operator. When the input operator inputs a check value, YES is input in S3 and S16, and S1 is input.
7. Writing is performed. FIG. 6 is an explanatory diagram illustrating an example of the check value displayed in S15.

After the contents of the check value data file 9 are satisfied, the input operator may always input NO in S3. S5 is YES and S8 is NO and S
If there is an error display of No. 9, the program proceeds to S15, where the check value serving as the criterion for the error display is displayed, so that the input operator is aware of the input error or the check value is incorrect. notice. If the check value is invalid, YES is input in S16, the check value is updated in S17, the content of the check value data file 9 is updated in S18, and the check processing in S7 is performed with the updated check value. Therefore, the input data may be checked OK in the determination in S8. The result of sequentially inputting each item is as shown in FIG. 7, for example.

[0016]

As described above, according to the present invention, the input operator for updating the database can freely select the selected value to simplify the input operation, and can freely set the check value. To prevent an input error.
