Abstract

A data transfer control device issues a session key identifying an application running on a user terminal. Then the device specifies a first database as a transfer destination of data input into a common data field for the first and a second database and outputs the data to an application process together with a session key. The device then inputs the data in the common data field together with the session key from the application process and updates the first database. After that, the device retrieves and outputs the data requested by the application process from the updated first database.

Claims

1. A data transfer control device for synchronizing inputs to a first and a second database having different field definitions and outputs to an application process running on a user terminal, comprising:

a session management device issuing a session key identifying said application process;

a value transfer destination management device specifying said first database as the transfer destination of data input into a data field in said second database common to the first and second databases and outputting the transfer destination to said application process together with said session key;

a database management device inputting the data in the common data field received from said application process together with said session key and updating said first database; and

a data request processing device retrieving and outputting the data requested by said application process from said updated first database.

2. The data transfer control device according to claim 1, wherein said value transfer destination management device specifies the transfer destination of the input data of the common data field using a URL of said first database and said session key.

3. The data transfer control device according to claim 1, wherein

said session management device, when said session key is issued, inputs identifying information of said user terminal, and

said value transfer destination management device retrieves from said first database a business object linked to the identifying information of the user terminal input by said session management device and a settings form indicating whether or not to display certain fields within said business object, and then specifies said transfer destination and outputs the business object and settings form together with said session key.

4. The data transfer control device according to claim 1, wherein said database management device, when updating said first database, specifies a business object into which to input the data from said common data field, based on the session key input by said application process.

5. The data transfer control device according to claim 3, wherein said database management device, when updating said first database, specifies a business object into which to input the data from said common data field, based on the session key input by said application process.

6. A data transfer control method for synchronizing inputs to a first and a second database having different field definitions and outputs to an application process running on a user terminal, comprising:

issuing a session key identifying said application process;

specifying said first database as the transfer destination for data input into a data field in said second database common to said first and second databases and outputting the transfer destination together with said session key to said application process;

inputting the data of said common data field from said application process together with said session key to update said first database; and

retrieving and outputting the data requested by said application process from said updated first database.

7. The data transfer control method according to claim 6, wherein the transfer destination of the input data to said common data field is specified using a URL of said first database and said session key.

8. The data transfer control method according to claim 6, further comprising:

when said session key is issued, inputting identifying information for said user terminal,

retrieving from said first database a business object linked to the identifying information of said user terminal and a settings form indicating whether to display or not display certain fields within said business object,

specifying said transfer destination, and

outputting the business object and settings form together with said session key.

9. The data transfer control method according to claim 8, further comprising:

when said session key is issued, inputting identifying information for said user terminal,

retrieving from said first database a business object linked to the identifying information of said user terminal and a settings form indicating whether to display or not display certain fields within said business object,

specifying said transfer destination, and

outputting the business object and settings form together with said session key.

10. The data transfer control method according to claim 6, further comprising, when said first database is updated, specifying a business object into which to input the data from said common data field, based on the session key input from said application process.

11. The data transfer control method according to claim 8, further comprising, when said first database is updated, specifying a business object into which to input the data from said common data field, based on the session key input from said application process.

12. The data transfer control method according to claim 9, further comprising, when said first database is updated, specifying a business object into which to input the data from said common data field, based on the session key input from said application process.

13. A computer-readable medium on which is stored a set of instructions for synchronizing inputs to a first and a second database having different field definitions and outputting to an application process running on a user terminal, which instructions when executed perform stages comprising:

issuing a session key identifying said application process;

specifying said first database as the transfer destination of data input into a data field in said second database common to said first and second databases and outputting the transfer destination together with said session key to said application process;

inputting the data in said common data field received from said application process together with said session key and updating said first database; and

retrieving and outputting the data requested by said application process from said updated first database.

14. The computer-readable medium according to claim 13, wherein the transfer destination for the input data to said common data field is specified using a URL of said first database and said session key.

15. The computer-readable medium according to claim 13, wherein the performed stages further comprise:

when said session key is issued, inputting identifying information for said user terminal; and

retrieving from said first database a business object linked to the identifying information of said user terminal and a settings form indicating whether to display or not display certain fields within said business object, and then specifying said transfer destination, and outputting the business object and settings form together with said session key.

16. The computer-readable medium according to claim 13, wherein the performed stages further comprise, when said first database is updated, specifying a business object into which to input the data from said common data field, based on the session key input from said application process.

17. The computer-readable medium according to claim 15, wherein the performed stages further comprise, when said first database is updated, specifying a business object into which to input the data from said common data field, based on the session key input from said application process.
