Data relay method and data relay apparatus

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.

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.
