Abstract

A data relay apparatus has a plurality of conversion process parts installed therein and the plurality of conversion process parts are prepared for respective types of data items transmitted from a first data processing apparatus used as a data transmission source. The conversion process parts are software parts which convert data items of respective types. The data relay apparatus includes a data reception processing section which receives data transmitted from the first data processing apparatus, a data conversion processing section which determines a type of data received, retrieves one of the conversion process parts which is prepared for the data and starts the conversion process parts, and a data transmission processing section which transmits data converted by the conversion process part to a second data processing apparatus.

Claims

1. A data relay method of a computer which receives data from a first data processing apparatus, converts the data into data which is processable in a second data processing apparatus and then transmits the thus converted data to the second data processing apparatus, the computer having a plurality of conversion process parts which are prepared for respective types of data items to be transmitted from the first data processing apparatus and convert data items of the respective types into data items processable in the second data processing apparatus, comprising:

receiving data from the first data processing apparatus,

determining a type of the received data,

retrieving one of the conversion process parts which is prepared for the determined type of data,

starting the retrieved conversion process part, and

transmitting data converted by the conversion process part to the second data processing apparatus.

2. The data relay method according to claim 1, further comprising permitting the computer to hold a data conversion result by the conversion process part as log data.

3. A data relay apparatus provided between a first data processing apparatus and a second data processing apparatus, comprising:

a part storage section which stores a plurality of conversion process parts formed for respective types of data items transmitted from the first data processing apparatus to the second data processing apparatus and used to convert data items of the respective types,

a receiving section which receives data from the first data processing apparatus,

a determining section which determines a type of data received by the receiving section,

a retrieving section which retrieves one of the conversion process parts which is formed for the type of data determined by the determining section from the part storage section,

a starting section which starts the conversion process part retrieved by the retrieving section, and

a transmitting section which transmits data converted by the conversion process part to the second data processing apparatus.

4. The data relay apparatus according to claim 3, further comprising a log holding section which holds a data conversion result by the conversion process part started by the starting section as log data.

5. The data relay apparatus according to claim 4, wherein the log data contains at least one of a file name of data received from the first data processing apparatus, identification data which specifies the first data processing apparatus, identification data which specifies a type of data and reception date and time.

6. The data relay apparatus according to claim 3, further comprising a process determination table which stores part numbers specifying the conversion process parts used to convert various data items transmitted from the first data processing apparatus to data items processable in the second data processing apparatus according to a plurality of identification data items which respectively specify the data items from the first data processing apparatus,

wherein the retrieving section retrieves a part number which is set according to identification data used to specify data determined by the determining section from the process determination table.

7. The data relay apparatus according to claim 3, wherein the receiving section, determining section, retrieving section, starting section and transmitting section are realized by use of one application program used as a basis.

8. The data relay apparatus according to claim 3, wherein the conversion process part includes an argument reception processing section which receives and holds an argument used for data conversion, a conversion processing section which converts data by use of the argument held in the argument reception processing section, and a result response processing section which forms a parameter indicating the data conversion result.

11. A conversion process part installed in the data relay apparatus described in claim 3, comprising:

an argument reception processing section which receives and holds an argument used for data conversion,

a conversion processing section which converts data by use of the argument held in the argument reception processing section, and

a result response processing section which forms a parameter indicating the data conversion result.

9. A computer-readable program of a computer which receives data from a first data processing apparatus, converts the data into data which is processable in a second data processing apparatus and then transmits the thus converted data to the second data processing apparatus, comprising:

permitting the computer to perform a storage function of storing a plurality of conversion process parts which are prepared for respective types of data items to be transmitted from the first data processing apparatus and convert the data items of the respective types into data items processable in the second data processing apparatus,

permitting the computer to perform a receiving function of receiving data from the first data processing apparatus,

permitting the computer to perform a determining function of determining a type of received data,

permitting the computer to perform a retrieving function of retrieving one of the conversion process parts which is prepared for the determined type of data,

permitting the computer to perform a starting function of issuing an instruction of starting the retrieved conversion process part, and

permitting the computer to perform a transmitting function of transmitting data converted by the conversion process part to the second data processing apparatus.

10. The computer-readable program according to claim 9, further comprising a holding function which is realized by the computer to hold a data conversion result by the conversion process part as log data.
