Abstract

PROBLEM TO BE SOLVED: To provide a table management system in which plural table format processing can be operated by the same device, and the same processing can be executed even when the table format is changed. SOLUTION: A leading pointer 11 points a table management area 21 of a table 2. When the table leading of the table 2 is necessary, a base pointer in the table management area 21 is referred to. Also, a management area 31 of a table 3 following the table 2 is included as the pointer of the next table in the table management area 21, and this is used. The pointer of the table management area 21 of the previous table 2 and the pointer of a table management area 41 of a next table 4 are included in the table management area 31 of the table 3. Thus, tables adjacent to the table 3 can be provided by referring to the table management area 31 without considering the format of the overall table 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table management system on a memory, and more particularly, to a table management system when a plurality of types of tables are used in combination.

[0002]

2. Description of the Related Art Conventionally, in this type of table management system,
A pointer indicating the table immediately before the table and a pointer indicating immediately after the table are set and managed independently in each of the plurality of tables. Alternatively, management is performed by setting a part of each table to be the same between the tables.

[0003]

In the conventional table management method described above, a pointer indicating a table immediately before a table and a pointer indicating immediately after a table are set and managed independently for each table format. Get the table just before a table, add the table just before a table, delete the table just before a table, get the table just after a table, add the table just after a table It is necessary to prepare a number of devices that perform the basic operations of the queue, such as deleting the table immediately after a certain table, by the number of types in the table format. There was a disadvantage of becoming.

[0004] Therefore, in order to unify the devices for processing the tables, it is not possible to set the position for storing the pointer indicating the table immediately before the table and the position for storing the pointer indicating the table immediately after the table to the same position in each table format. It is difficult when each table format is associated with an independent number of queues, and it is also difficult to change the table format later.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a table management system in which processing in a plurality of table formats is performed by the same apparatus, and the same processing can be performed even if the table format is changed. is there.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a multi-data format table for unifying a program using a table having a plurality of formats and a table having a plurality of formats using a queue structure. In the management method, a management table and a plurality of data tables having a plurality of formats are provided. Each of the plurality of data tables includes a pointer indicating a table immediately before the table, a pointer indicating a table immediately after the table, and a table. By providing a table management area having a head pointer indicating the head, it is possible to perform repetition between a plurality of data tables irrespective of a plurality of formats. This is a multi-data format table management system characterized by performing operations.

It is preferable that the management table includes a plurality of head pointers.

Further, it is preferable that one of the plurality of head pointers points to one table management area of the plurality of data tables.

Further, when the table management area of the plurality of data tables needs the head of the plurality of data tables, it is preferable to provide a base pointer in the table management area.

[0010] Further, of the plurality of data tables, a table management area of one data table includes a pointer of a table management area of a data table preceding one data table, and a table management area of a table management area next to one data table. It is more preferable to have a pointer.

In the table management method of the present invention, management is performed using a pointer indicating the head of a table queue and a table management area provided in each of all tables. The table management area stores a pointer indicating the table management area of the table immediately before the own table, a pointer indicating the table management area of the table immediately after the own table, and a pointer indicating the head of the own table called a base pointer. One table has one or more management areas,
The base pointers of all management areas on one table are set so as to point to the head of the table managed by that management area. To obtain the table immediately before or after a table from a certain table, only the table management area is handled,
To refer to and change the contents of the table, the table head is acquired from the base pointer, and processing unique to each table is performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a structure of an embodiment of a table management system of a plural data format according to the present invention. The table management method of the multiple data format of the present embodiment includes a management table 1, a first data table 2, a second data table 3, a third data table 4, a fourth data table 5, The fifth data table 6 and the sixth data table
And a data table 7. Management table 1
Are the first start pointer 11 and the second start pointer 1
2 and a third head pointer 13. The first data table 2 has a table management area 21. The second data table 3 has a table management area 31. The third data table 4 has a table management area 41. The fourth data table 5 has a table management area 51. Fifth data table 6
Has a table management area 61 and a table management area 62. The fifth data table 7 includes a table management area 71 and a table management area 72.

Each of the positions is connected from the first head pointer 11 to the first data table 2, first to the second data table 3, and finally to the third data table 4. From the second head pointer 12, the fourth data table 5, the fifth data table 6, and finally the sixth data table 7 are connected. From the third head pointer 13, the sixth data table 7 is connected to the fifth data table 6 and finally.

Next, the operation of the multiple data format table management system of the present invention will be described with reference to FIG.

The first head pointer 11 points to the table management area 21 of the first data table 2. First
When the head of the data table 2 is required, the base pointer in the table management area 21 is referred to. Also, a second data table 3 following the first data table 2
The management area 31 is used as a pointer of the next table in the table management area 21. Since the table management area 31 of the second data table 3 includes the pointer of the table management area 21 of the first data table 2 and the pointer of the table management area 41 of the next third data table 4, the second The table adjacent to the second data table 3 is obtained only by referring to the table management area 31 without being aware of the format of the entire data table 3. The same operation is performed for the other tables, and the adjacent table and the head of the table are referred to by operating the table management area.

[0016]

As described above, the present invention can be used to acquire an adjacent table, insert another table immediately before or immediately after a table, or delete a table immediately before or immediately after a table. Since the operation is performed only in the table management area, the table can be processed by the same queue processing apparatus regardless of the type of the table format. There is an effect that even if the format is changed, it becomes possible by the same table operation.
