Abstract

A database management method and a database management system are provided. A management server generates data which is described in the same data format as the data stored in a database and adds the generated data in the database. The data format includes a column for inputting information indicating whether or not the data is sorted.

Claims

1. A database management method comprising:

generating data which is described in a data format that is the same format as data stored in a database; and

adding the generated data in the database,

wherein the data format includes a column for inputting information indicating whether or not the data is sorted.

2. The database management method according to claim 1,

wherein the data format comprises:

a column data part which includes data for each column and identification information for each data; and

a permutation matrix part which includes order information indicating the order of the identification information.

3. The database management method according to claim 2, further comprising:

updating the identification information of the generated data in order not to overlap with the identification information of the data stored in the database, when the identification information of the generated data overlaps with the identification information of the data stored in the database.

4. The database management method according to claim 2,

wherein the column data part includes region identification information indicating a group of the data.

5. A database management system comprising:

a database configured to store data;

a management server configured to generate data which is described in a data format that is the same format as the data stored in the database and add the generated data in the database,

wherein the data format includes a column for inputting information indicating whether or not the data is sorted.

6. The database management system according to claim 5,

wherein the data format comprises:

a column data part which includes data for each column and identification information for each data; and

a permutation matrix part which includes order information indicating the order of the identification information.

7. The database management system according to claim 6,

wherein the management server updates the identification information of the generated data in order not to overlap with the identification information of the data stored in the database when the identification information of the generated data overlaps with the identification information of the data stored in the database.

8. The database management system according to claim 6,

wherein the column data part includes region identification information indicating a group of the data.

9. A computer readable medium recording thereon a program for enabling a computer to perform a database management method, the method comprising:

generating data which is described in a data format that is the same format as data stored in a database; and

adding the generated data in the database,

wherein the data format includes a column for inputting information indicating whether or not the data is sorted.

10. The computer readable medium according to claim 9,

wherein the data format comprises:

a column data part which includes data for each column and identification information for each data; and

a permutation matrix part which includes order information indicating the order of the identification information.

11. The computer readable medium according to claim 10, the method further comprising:

updating the identification information of the generated data in order not to overlap with the identification information of the data stored in the database when the identification information of the generated data overlaps with the identification information of the data stored in the database.

12. The computer readable medium according to claim 10,

wherein the column data part includes region identification information indicating a group of the data.
