Abstract

An automatic data download system and method for downloading data from a remote server (3) to a local database (20) via a communications network (8). The automatic data download system checks the local database before downloading required data from the remote server, and downloads only the data that are not stored in the local database. The automatic data download system includes a data check unit (11) installed in a client computer (1) which is electronically connected with the local database for checking data stored in the local database against data required to be downloaded; a data download unit (12) installed in the client computer for automatically downloading data that are required to be downloaded and that are not already stored in the local database; and a recording unit (13) installed in the client computer for recording data still not downloaded or not successfully downloaded.

Claims

1. An automatic data download system, comprising:

a local database;

a data check unit installed in a client computer which is electronically connected with the local database for checking data stored in the local database against data required to be downloaded; and

a data download unit installed in the client computer for automatically downloading data that are required to be downloaded and that are not already stored in the local database.

2. The system as claimed in claim 1, further comprising a recording unit installed in the client computer for recording data still not downloaded or not successfully downloaded.

3. The system as claimed in claim 1, wherein the local database is installed in the client computer.

4. The system as claimed in claim 1, wherein the local database is installed in a local server that is connected with the client computer via an electronic communications network.

5. The system as claimed in claim 4, wherein the electronic communications network comprises an intranet.

6. An automatic data download method for downloading data from a remote server to a local database via a communications network, the method comprising the steps of:

downloading a title list of required data from the remote server to a log according to a download requirement set up by a user;

checking the title list of the log against data stored in the local database; and

downloading data of titles recorded in the title list of the log from the remote server to the local database, wherein said data are not already stored in the local database.

7. The method as claimed in claim 6, further comprising the step of:

deleting from the title list of the log all titles whose data are already stored in the local database.

8. The method as claimed in claim 6, wherein the step of downloading data of titles recorded in the title list of the log from the remote server to the local database comprises the steps of:

retrieving a title from the title list of the log;

downloading data of the title from the remote server to the local database; and

deleting the title from the title list of the log after the data of the title are successfully downloaded.

9. The method as claimed in claim 6, further comprising the step of:

re-downloading any of said data that are not successfully downloaded.

10. An automatic data download method for downloading data from a remote server to a local database via a communications network, the method comprising the steps of:

downloading a title list of required data from the remote server to a log according to a download requirement set up by a user;

checking the title list of the log against data stored in the local database;

deleting from the title list of the log all titles whose data are already stored in the local database; and

downloading data of titles recorded in the title list from the remote server to the local database, wherein said data are not already stored in the local database.

11. The method as claimed in claim 10, wherein the step of downloading data of titles recorded in the title list from the remote server to the local database comprises the steps of:

retrieving a title from the title list of the log;

downloading data of the title from the remote server to the local database; and

deleting the title from the title list of the log after the data of the title are successfully downloaded.

12. The method as claimed in claim 10, further comprising the step of:

re-downloading any of said data that are not successfully downloaded.

13. An automatic data download method for downloading data from a remote server to a local database via a communications network, the method comprising the steps of:

(a) downloading a title list of required data from the remote server to a log according to a download requirement set up by a user;

(b) checking the title list of the log against data stored in the local database;

(c) deleting from the title list of the log all titles whose data are already stored in the local database;

(d) retrieving a title from the title list of the log;

(e) downloading data of the title from the remote server to the local database;

(f) deleting the title from the title list of the log after the data of the title are successfully downloaded;

(g) repeating steps (d) through (f) until a last title in the title list is retrieved and its data successfully downloaded; and

(h) re-downloading any data that are not successfully downloaded.
