Abstract

A database server 1 accessible to/from a client 9 via a network includes a reception and transmission portion 8 which sends/receives data to/from the clients 9, a data storage portion 2 having a client data storage region 3 which stores client data corresponding to the client 9, a data management portion 5 which manages the client data, an information collection condition set portion 6 which, when the client data is modified, sets an information collection condition for specifying such information data as to be required by the client 9 in the future based on the modification, and an information creation portion 7 which creates the information data by a search according to the information collection condition.

Accordingly, the database server 1 allows the client 9 to access information at high speed while reducing a user'"'"'s operation load and a client 9'"'"'s communication load.

Claims

1. A database server accessible to/from a client via a network, comprising:

reception and transmission means for sending/receiving data to/from the client;

data storage means having a client data storage region which stores client data corresponding to the client;

client data management means for managing the client data;

information collection condition set means for setting, when the client data is modified, an information collection condition for specifying such information data as to be required by the client in future based on the modification; and

information data creation means for creating the information data by a search performed according to the information collection condition.

2. The database server set forth in claim 1, wherein:

the client is informed of the creation of the information data.

3. The database server set forth in claim 1, wherein:

the client is informed of the information collection condition.

4. The database server set forth in claim 1, wherein:

the information collection condition set means is actuated upon access to/from the client.

5. The database server set forth in claim 1, wherein:

the information collection condition set means modifies the information collection condition based on client'"'"'s instructions.

6. The database server set forth in claim 1, wherein:

the information collection condition set means sets the information collection condition with reference to a keyword table which corresponds to an attribute of the client data.

7. The database server set forth in claim 1, wherein:

the information collection condition set means sets the information collection condition based on a network address which corresponds to an attribute of the modified client data.

8. The database server set forth in claim 1, wherein:

the information collection condition set means sets the information collection condition by using a record of information data collection performed in the past.

9. The database server set forth in claim 1, wherein:

the information data creation means searches the data storage means.

10. The database server set forth in claim 1, wherein:

the information data creation means stores in the data storage means the created information data in association with the client data.

11. The database server set forth in claim 1, wherein:

the information data creation means causes the created information data to include presentation format control data which controls a format in which the client data is presented by the client.

13. The database server set forth in claim 1, wherein:

the information collection condition set means sets the information collection condition by using separate client information.

14. The database server set forth in claim 13, wherein:

the separate client information includes information on use status of the information data created by the information creation means in the past.

17. A computer-readable recording medium in which the information management program of claim 16 is recorded.

12. The database server set forth in Claim l, wherein:

the client data management means modifies the client data based on an instruction given from a different server capable of accessing the network.

15. A database server accessible to/from a client via a network, comprising:

reception and transmission means for sending/receiving data to/from the client;

data storage means having a client data storage region which stores client data corresponding to the client;

information collection condition set means for detecting a data modification in the client data storage region and setting an information collection condition for specifying such information data as to be required by the client in future based on results of the detection; and

information data creation means for creating the information data by a search performed according to the information collection condition.

16. A server-executable information management program, comprising the steps of:

detecting a modification in such client data corresponding to each client that is under management of the server;

setting an information collection condition for specifying such information data as to be required by the client in future based on the modification; and

creating the information data by a search performed according to the information collection condition.

18. An information management method which allows a server to manage information corresponding to each client, comprising the steps of:

detecting a data modification in a client data storage region, the client data corresponding to each client;

setting an information collection condition for specifying such information data as to be required by the client in future based on the data modification thus detected; and

creating the information data by a search performed according to the information collection condition thus set.
