Abstract

PURPOSE:To easily recognize new/old change contents of each item at the time of display of individual information and to automatically erase unnecessary information with respect to the information processor provided with the version management function. CONSTITUTION:At each time of the change of individual information, new information is stored as the updated information in an individual information storage area 13a of a RAM 13, and old information is stored there in the order of change as the history information. A CPU 11 displays individual information on a display part 16 in such form based on the updated information and history information stored in the individual information storage area 13a that new/old change contents of each item can be understood. While the period when the history information should be erased is set to an erase period storage area 13c, the CPU 11 detects a history information, which is not accessed in this designated period, to process it as the erase object.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus having a version management function, and in particular, it divides the name, family structure (organizational structure), address, telephone number, etc. into individuals and companies. The present invention relates to an information processing device and a control method for managing information on each item.

[0002]

2. Description of the Related Art Conventionally, some information processing apparatuses having a version management function store new information as update information and old information as history information when changing stored information. is there. In this case, normally, only the new information is displayed, and the history information of the designated date and time is displayed by instructing the change date and time, for example.

Further, in this type of information processing apparatus, by designating a deletion period, there is one that deletes the history information after the specified period. That is, when the history information is stored for several years, for example, if the erasing period is 3 years, the history information after 3 years has passed is detected and the history information is erased from the memory.

[0004]

In the information processing apparatus as described above, information on each item such as name, family composition (organizational composition), address, telephone number, etc. is divided into individual versions and company versions. If you manage, you can see at a glance the old and new changes such as what the maiden name was, how the family structure was changed, what the old address was, for example, by individual. Display is desired. However, in the past, the past information was only selectively displayed by instructing the date and time of the change, and thus the change could not be grasped only by the display.

In the past, when erasing information, in the past, history information after a designated period has been automatically deleted. However, some history information is required even if the designated period has elapsed. Especially in the individual information as described above,
There is a possibility that the past information may be used even after the specified period has passed, and it was extremely troublesome to erase only the information for a certain period of time.

The present invention has been made in view of the above points, and when individual information is displayed, it is possible to easily grasp the old and new change contents for each item, and to automatically display only unnecessary information. It is an object of the present invention to provide an information processing apparatus and a control method that can be erased physically.

[0007]

The present invention comprises display means for displaying individual information composed of a plurality of items, and stores new information as update information in the storage means each time the individual information is changed. , The old information is stored in the same storage means as history information in the order of change, and when history display is not instructed, the individual information is displayed in the display means based on the update information stored in the storage means. When the history display is instructed, the individual information can be identified for each item based on the update information and the history information stored in the storage means so that the old and new changes can be identified. Is displayed on the display means.

The present invention further comprises display means for displaying the individual information, and stores new information as update information in the storage means each time the individual information is changed, and
The old information is stored in the same storage means as history information in the order of change, and the history information that has not been accessed for the designated period is detected by designating a period for deleting the history information. The history information is prohibited from being displayed, and the history information whose display is prohibited is erased from the storage means at a predetermined timing.

[0009]

With the above structure, when displaying individual information,
Based on the update information and the history information stored in the storage means, the individual information is displayed on the display means in a format such that the new and old changes can be understood for each item. Therefore, the history information of the individual information can be checked against the current information, and the old and new changes can be easily grasped for each item.

Further, when the history information is erased, the history information which has not been accessed for a designated period is detected as an object to be erased, and its display is prohibited, and then the history information is erased from the storage means at a predetermined timing. Therefore, in the present invention in which the access condition is added, it is possible to delete only really unnecessary history information, as compared with the conventional method of deleting only the temporal condition. Further, for example, since the main erasure is first performed at the timing when the capacity of the storage means is full, it is possible to easily restore even the history information to be erased before the capacity is full. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a main part of an information processing apparatus having a version management function. In FIG. 1, a CPU 11 controls the entire apparatus. Here, the ROM 12 and the RAM 13 are accessed and a program according to an input instruction is activated to execute a version management control process and the like.

The ROM 12 has a program area 12a for storing a program necessary for starting the CPU 11.
Also, a font area 12b for storing font data used for display is provided.

The RAM 13 is provided with an individual information storage area 13a for storing individual information, a display type storage area 13b for storing a display type, an erase period storage area 13c for storing an erase period, and the like. There is.

The above-mentioned individual information has various kinds of information input for each item such as name, family structure (organizational structure), address, telephone number, etc. for each individual or company. In this embodiment, in the individual information area 13a, as shown in FIG. 2, new information is stored as update information and old information is stored as history information in the order of change each time the individual information is changed. There is. In addition, this individual information area 13
The creation date, the latest access date, and the temporary deletion flag are stored in a.

The above-mentioned display type indicates a type for displaying individual information, and includes display types 0 to n (n is the number of history information). The type displayed previously is stored in the display type storage area 13b.

The erasing period is an access period for erasing unnecessary history information and is arbitrarily designated by the user. In this embodiment, this erasing period indicates a tentative erasing period in which display is prohibited and is not a main erasing period in which data is actually erased from the memory.
This erasure is performed at the timing when the memory is full.

The input unit 14 is composed of, for example, a keyboard and is used to input information such as character codes and commands. The input control unit 15 controls the input of the information input by the input unit 14. The display unit 16 is composed of, for example, a liquid crystal display (LCD), and displays various information such as individual information. The display control unit 17 uses a VRAM (video R
AM) 18 is used to perform display control on the display unit 16. Display data to be displayed on the display unit 16 is stored in the VRAM 18.

A floppy disk device (hereinafter referred to as FDD) 19 is used as an external storage device, and is used here for storing individual information. The floppy disk controller (hereinafter referred to as FDC) 20 is an FDD
The control of 19 is performed.

Further, a real timer 21 is provided in this apparatus. The real timer 21 counts the current date and time, and is used for managing the erasing period as well as the creation date of the individual information and the latest access date.

Next, the operation of the embodiment will be described. Here, in the information processing apparatus having the version management function, (a) individual information display control processing and (b) individual information deletion control processing will be described separately.

(A) Display control processing of individual information When version information of each item such as name, family structure (organizational structure), address, telephone number, etc. is managed, for example, by individual, what is the maiden name? It is desirable to have a display that shows at a glance the old and new changes such as how the family structure was changed and what the old address was.
Therefore, the present invention is characterized in that, when displaying the individual information, it is displayed in a format in which the old and new changed contents can be understood for each item.

Assume that individual information is changed as shown in FIGS. 3 (a) to 3 (c), for example. Figure 3 (a)
Indicates individual information at the initial stage (creation date “91-1-1”). In this case, the individual information in FIG. 3A is stored in the individual information storage area 13a of the RAM 13 as update information (new information). Figure 3 (b) shows one year later (created date "9
2-1-1 ") shows the case where the individual information is changed. In this case, the individual information of FIG. 3B is set as update information (new information), and the individual information of FIG. 3A is set as history information and stored in the individual information storage area 13a. Figure 3
(C) shows the case where the individual information is changed one year later (creation date “93-1-1”). In this case,
The individual information in (c) is used as update information (new information), and the individual information in FIGS. 3A and 3B is stored as history information in the individual information storage area 13a in the order of change.

When the individual information is changed in this way, normally only the latest individual information is displayed several times as shown in FIG. When the latest individual information is displayed, the "history" switch 31a and the "all history" switch 31b are displayed for each case on the display screen. The "history" switch 31a is a switch for viewing the previous history information of the individual information. The "all history" switch 31b is a switch for viewing all history information of the individual information.

When the "history" switch 31a is selected with a cursor or the like (in the pen input method using a tablet,
By pointing the display of the "history" switch 31a), the previous history information is displayed as shown in FIG. In this case, not only the previous history information is displayed, but also the update information (new information) is displayed in a format such that the old and new changes can be understood.
FIG. 6A shows a format example when displaying the previous history information. For example, when the family structure is changed, the date of change is added to the current family. If the address has been changed, the current address and old address are displayed together with the date of change.

When the "all history" switch 31b is selected, all history information is displayed as shown in FIG. 5 (b). Also in this case, not only all the history information is displayed, but also the update information (new information) is displayed in a format in which the old and new changes can be understood. Figure 6
An example of a format for displaying all history information is shown in (b). For example, if the address has been changed several times, the current address and a plurality of old addresses (old address 1, old address 2 ...) Are displayed together with the date of change.

As shown in FIG. 5A, when the previous history information is displayed, the "History" switch 31a, "All history" switch 31b and "Latest" switch 31c are displayed on the display screen. It "Latest" switch 31c
Is a switch for viewing the latest information (current individual information). The "history" switch 31a is a switch for viewing the previous history information, but is not displayed when there is no more history information. On the other hand, FIG.
In the state where all history information is displayed as shown in (b),
Only the "latest" switch 31c is displayed on the display screen.

As described above, by operating the "history" switch 31a or the "all history" switch 31b, it is possible to see the history information of the individual information in comparison with the current information. When the power is turned off while the screen is switched by operating the "history" switch 31a or the "all history" switch 31b, the display type indicating the display state is held in the display type storage area 13b of the RAM 13, When the power is turned on again, the type displayed before is displayed. This is because it is highly likely that the history information displayed before will be seen when the system is restarted.

FIG. 7 is a flow chart showing the switch changing operation of the embodiment. When displaying individual information, CP
U11 first detects the number n of history information held by the individual information (step A1). At this time, temporarily erased information is not displayed because of the (b) individual information erasure control processing, which will be described later, and is excluded here.

When the "latest" switch 31c is operated (step A2), the CPU 11 sets the display type P to "0".
(Step A3). Then, the CPU 11 displays the individual information of the display type 0 on the display unit 16 (step A4). Note that specific display processing for each type will be described later with reference to FIG. Also, CPU1
1 stores the display type P (0 to n) at this time in the display type storage area 13b of the RAM 13, and when the individual information is displayed next time, the display type P stored in the display type storage area 13b It is displayed (step A5).

When the "history" switch 31a is operated (step A6), the CPU 11 updates the current display type P by "+1" (step A7). At this time, if the updated display type P is larger than the number n of history information (Yes in step A8), the display type P is set to “n”.
The process of stopping at is performed (step A9). Thereafter, similarly to the above, the CPU 11 displays the individual information of the display type P on the display unit 16 (step A4), and stores the display type P at that time in the display type storage area 13b (step A).
5).

When the "all history" switch 31b is operated (step A6), the CPU 11 displays the current display type P.
Is set to "n" (step A7). Thereafter, similarly to the above, the CPU 11 displays the individual information of the display type P on the display unit 16 (step A4), and stores the display type P at that time in the display type storage area 13b (step A).
5).

FIG. 8 is a flow chart showing the type-specific display processing operation of the embodiment. First, the CPU 11 has RA
The update information (new information) of the individual information is read from the individual information storage area 13a of M13, and is displayed on the display unit 1
No. 6 is displayed (step B1). Here, the CPU 11 reads the display type P stored in the display type storage area 13b, and if it is the display type 0 (Yes in step B2), it is determined that the latest information is displayed, and the processing here is ended. To do.

When the display type P is other than "0" (No in step B2), the CPU 11 displays the display counter A.
Is set to "1" (step B3), and 1 of the individual information is set.
The previous history information is read from the individual information storage area 13a (step B4). The display counter A is for counting how many pieces of history information have been read out,
For example, it is provided in the RAM 13. And CPU1
1 performs a specific display (changes the screen) based on the history information read at this time and the update information already read. At this time, the latest access date added to the history information is changed to the current date in relation to (b) individual information deletion control processing described later (step B6).

When the number indicated by the display counter A is smaller than the number indicated by the display type P (Yes in step B7), CP
U11 updates the display counter A by "+1" (step B8) and repeats the processing from step B4. In this way, the individual information for each type is displayed.

(B) Individual information erasure control processing In this type of information processing apparatus, there is a method of erasing history information that has passed the designated period by designating an erasing period, but this method is necessary. There is a problem that even history information is deleted. Therefore, the present invention sets the history information that has not been accessed during the designated period of history information as a deletion target, and temporarily deletes the history information,
The erasing is characterized by a two-stage structure in which the main erasing is performed at the timing when the memory is full.

For example, assume that there is history information 1 to 5 as shown in FIG. The date of creation and the latest access date are added to each piece of history information 1-5. The creation date is the date on which the history information is created, and the latest access date is the date on which the history information is most recently accessed (the "history" switch 31a
Alternatively, it is the date when the history information is displayed by the "all history" switch 31b).

Here, assuming that the erasing period is, for example, two years, and if the current period is 93-1-1, it is assumed that two years have passed, and history information 3, history information 4, and history information 5 are detected. In the conventional method of erasing only the temporal condition, all the history information 3 to 5 are erased. The present invention also looks at access conditions. That is, the object that has been erased for two years and has not been accessed during that time is detected as an erasure target. In this example, history information 4 and history information 5 correspond to that.

In this way, history information 4 and history information 5
Is detected as an object to be erased, but in this case, it is not immediately erased from the memory, but the display control information, which is a temporary erase flag, is once set and the state is temporarily erased, that is, only the display is prohibited. This erasure is performed at the timing when the memory is full. This is because the history information that has not been accessed for a specified period may be needed later, so that the erasing is actually postponed and the situation is checked.

FIG. 10 is a flow chart showing the temporary erase operation of the embodiment. When deleting the history information, the CPU 11
First, the erase period X is set in the erase period storage area 13c of the RAM 13 (step C1). This erase period X
Is arbitrarily designated by the user. Next, CPU1
In No. 1, the personal information is read one by one from the individual information storage area 13a of the RAM 13 (step C2), and if there is information (Yes in step C3), the number n of history information of the individual information is detected ( Step C4).

Here, the CPU 11 sets the erase counter B to "1" (step C5), and the erase counter B is set.
The latest access date Y of the history information indicated by is detected (step C6). The erasure counter B is for counting which history information has been retrieved, for example RA
It is provided in M13. As a result of detecting the latest access date Y of the history information indicated by the erase counter B, if the latest access date Y is newer than the erase period X (No in step C7), the CPU 11 updates the erase counter B by “+1” ( In step C8), the next oldest history information is searched.

In this way, the processes from step C6 are repeated until the number indicated by the erase counter B reaches the number n of history information (step C9). During this time, when the history information whose latest access date Y is older than the erasure period X is detected (Yes in step C7), the CPU 11 determines that each history information including the history information and the history information thereafter is to be erased, and the history information is deleted. The temporary erase flag added to the history information is set to 1 to perform temporary erase (step C10). In the temporary erased state, as described in step A1 of FIG. 7, since the display target is excluded, the content cannot be seen on the display screen. Accordingly, when the amount of information is large, the amount of information viewed by the user can be limited, and the complexity can be reduced.

FIG. 11 is a flow chart showing the main erase operation of the embodiment. Each time the CPU 11 registers the individual information in the individual information storage area 13a of the RAM 13, it detects whether or not the capacity exceeds the allowable amount (step D1). As a result, if the allowable amount is exceeded (Yes in step D2)
s), the CPU 11 displays a message as shown in FIG. 12, for example, on the display unit 16 to warn the user that the main deletion will be performed (step D3). By this message display,
The user can decide whether or not the data can be erased.

If it is desired not to erase the main data (step D4
No.), for example, the individual information may be moved to the FDD 19. Further, for example, a temporary deletion list as shown in FIG. 13 can be displayed, and really unnecessary history information can be selected from the list, and only the history information can be permanently deleted.

When the main erasure is acceptable (step D4
When the instruction is received, the CPU 11 erases all the temporarily erased history information from the individual information storage area 13a based on the temporary erase flag currently set in the individual information storage area 13a ( Step D
5).

In this way, the main erasure is performed only when the memory capacity is full. Therefore, even with respect to the history information to be erased, before the memory capacity is full, the actual data is still in the memory and can be easily restored.

If a command for main erasing is used, for example, the main erasing can be forcibly executed at any time regardless of the memory capacity. There are two main erasing methods. One is a method of erasing all the temporarily erased history information, and another is a method of erasing the oldest history information in order. Although the former method is used in the above-described embodiment, the latter method can be easily realized by adopting a configuration in which the main erasure is performed based on the latest access of the history information.

In the above embodiment, the history information of the individual information is erased, but the entire individual information including the update information, that is, the new information is erased, and temporarily erased when no access is made for a designated period. It is also possible to further erase the book.

[0048]

As described above, according to the present invention, when the individual information is displayed, the old and new change contents of the individual information can be known for each item based on the update information and the history information stored in the storage means. Since it is displayed on the display means in such a format, it is possible to see the history information of the individual information in comparison with the current information, and it is possible to easily grasp the old and new changes for each item.

Further, when erasing the history information, the history information that has not been accessed for the designated period is detected as the erasure target, so that only the history information that is really unnecessary can be erased. In this case, after erasing the history information to be erased (display is prohibited), for example, the main erasing (actual erasing from the memory) is performed at the timing when the memory capacity is full. Therefore, even the history information to be erased can be easily restored as needed before the memory capacity is full.
