Abstract

A data management system allows various forms of data to be centrally managed. The system includes a first storage unit for storing different types of data files, each including a keyword. A second storage unit stores the keywords associated with the different types of data files. A third storage unit stores location information of the individual keywords. When an arithmetic unit receives a keyword, it updates the keyword in the first storage unit based on the location information in the third storage unit.

Claims

1. A data management system, comprising:

a data input unit inputting data;

an operation unit connected to the data input unit and executing software tools performing a predetermined operation using the input data to produce data files having different formats, each data file including information represented by a keyword, wherein at least two of the data files include a common keyword;

a first storage unit storing the data files;

a second storage unit storing the keywords of data files;

a third storage unit storing location information indicating the data files including the keywords; and

an arithmetic unit in communication with the operation unit, in communication with the first, second and third storage units and in communication with the data input unit, and executing a management software tool receiving a keyword and update information corresponding to the keyword and updating the data files by using the update information to update in the data files information corresponding to the keyword, including updating the data files that commonly include the keyword, using the location information of the keyword.

2. The data management system according to claim 1, wherein said arithmetic unit selectively performs one of collective updating and partial updating in response to the input data, wherein in collective updating, common keywords included in the data files are collectively updated, and in partial updating, a portion of the common keywords are updated.

3. The data management system according to claim 1, wherein said arithmetic unit produces an updating management table including a relationship between the keywords and the data files and updating information representative of whether or not the keywords in the data files have been updated, the data files and the location information.

4. The data management system according to claim 3, wherein said first to third storage units are formed in a database and said arithmetic unit stores the updating management table in the database.

5. The data management system according to claim 4, wherein said arithmetic unit produces a version number table indicating numbers of times of updating of keywords and stores the version number table into said database.

6. The data management system according to claim 1, wherein said data input unit includes a display unit, and said arithmetic unit displays not updated keywords and data files including the not updated keywords on said display unit.

7. A method to manage data produced by computer systems, which execute software tools, comprising:

producing data files having different formats by executing the software tools, each data file including information represented by a keyword, at least two of the data files including a common keyword;

storing the data files, the keywords and location information indicating the data files including the keywords;

updating the data files by receiving a keyword and update information corresponding to the keyword and updating the data files by using the update information to update in the data files information corresponding to the keyword, including updating the data files that commonly include the keyword, using the location information of the keyword.

8. A method according to claim 7, wherein said updating further comprises selectively performing one of collective updating and partial updating in response to input data, wherein in collective updating, common keywords included in the data files are collectively updated, and in partial updating, a portion of the common keywords are updated.

9. A system managing data produced by computer systems executing software tools, comprising:

computer systems executing software tools producing data files having different formats, each data file including information represented by a keyword and at least two of the data files including a common keyword;

a storage unit in communication with the computer systems and storing the data files, the keywords and location information indicating the data files including the keywords;

a managing computer system in communication with the computer systems and the storage unit, and executing a management software tool receiving a keyword and update information corresponding to the keyword and updating the data files by using the update information to update in the data files information corresponding to the keyword, including updating the data files that commonly include the keyword, using the location information of the keyword.

10. A data management system in communication with a data input unit, a storage unit and computer systems, each computer system executing software tools producing data files having different format, each data file including information represented by at least one keyword and at least two of the data files including a common keyword, the data management system comprising

a processor, to store in the storage unit the data files, the keywords and location information indicating the data files including the keywords, to receive a keyword and update information corresponding to the keywords, and to update the data files by using the update information to update in the data files information corresponding to the keywords, including updating the data files that commonly include the keywords, using the location information of the keywords.

11. A data management system, comprising:

a data input unit inputting data;

an operation unit connected to the data input unit and executing software tools performing a predetermined operation using the input data to produce data files having different formats, each data file including a keyword, wherein at least two of the data files include a common keyword;

a first storage unit storing the data files;

a second storage unit storing the keywords of data files;

a third storage unit storing location information indicating the data files including the keywords; and

an arithmetic unit in communication with the operation unit, in communication with the first, second and third storage units and in communication with the data input unit, and executing a management software tool receiving a keyword and update information corresponding to the keyword and using the update information to update in the data files information corresponding to the keyword, including updating the data files that commonly include the keyword, using the location information of the keyword,

wherein the arithmetic unit displays the data files whose keywords have been updated and have not been updated in a table of the keywords and corresponding data files including the information corresponding to the keywords to urge an operator to confirm omission of updating or submission of updating.
