Abstract:
1. An information service system comprising: a plurality of service servers configured to carry out services, each of said service servers carrying out an individual service by a corresponding individual application; a single unified server provided in common to said plurality of service servers via network connection; and a terminal device using data held in said unified server, said unified server including: a first transmission/reception portion capable of practicing information transmission/reception with respect to each of said plurality of service servers and said terminal device using a common interface format; and a common database in a data format corresponding to said common interface format; each of said plurality of service servers including: a second transmission/reception portion capable of practicing information transmission/reception by means of using said common interface format with respect to said first transmission/reception portion of said unified server; a third transmission/reception portion capable of practice information transmission/reception with respect to a plurality of service terminals by means of using an interface format specific to said individual application, said plurality of service terminals using the individual application in common; and a data format conversion processing portion configured to carry out data format conversion processing between higher-rank data transmitted/received with respect to said unified server by means of using said common interface format through said second transmission/reception portion and lower-rank data transmitted/received with respect to said plurality of service terminals by means of using said specific interface format through said third transmission/reception portion; and said terminal device including: a fourth transmission/reception portion capable of practicing information transmission/reception with respect to said first transmission/reception portion of said unified server by means of using said common interface format; wherein said common database is an XML database using an XML format as said data format corresponding to said common interface; said second transmission/reception portion of said service server carries out information transmission/reception with respect to said first transmission/reception portion of said unified server by means of using said common interface format corresponding to the XML format; said data format conversion processing portion of said service server carries out said data format conversion processing between said higher-rank data in the XML format and said lower-rank data in the data format specific to said individual application; and said fourth transmission/reception portion of said terminal device carries out information transmission/reception with respect to said first transmission/reception portion of said unified server by means of using aid common interface format corresponding to the XML format; and wherein the information service system further comprises: an apparatus for producing RFID tags connected to said service server, said apparatus for producing RFID tags being configured to produce a RFID tag in which tag identification information corresponding to said lower-rank data is written via radio communication, wherein: said data format conversion processing portion coverts said lower-rank data in said specific data format corresponding to said tag identification information into said higher-rank data in said XML format in a form corresponding to the tag identification information; said common database stores and holds said higher-rank data in said XML format corresponding to said tag identification information; and said first transmission/reception portion of said unified server transmits, when receiving an inquiry signal including said tag identification information from said fourth transmission/reception portion of said terminal device or said second transmission/reception portion of said service server, a response signal to said fourth transmission/reception portion or said second transmission/reception portion, said response signal including said higher-rank data corresponding to said tag identification information.
