To detect an error beforehand on a manufacturing terminal device side before transmitting data from the manufacturing terminal device to a server device, and to cope therewith early.

The server device 1 is connected to manufacturing terminal devices 31-3n through a communication network 100, and when receiving a reception completion signal from the server device 1, the manufacturing terminal devices 31-3n output process data to the server device 1. The manufacturing terminal devices 31-3n have a structure description language file 31e for storing data wherein a database schema of a database device 12 is described, a structure description language analysis part 31a for determining whether a database schema of generated process data is fit to the database schema of the data stored in the structure description language file 31e or not, and a data output processing part 31b for outputting the process data to the server device 1 when determined to be fit thereto by the structure description language analysis part 31a.
