APPLICATION DEVELOPMENT SYSTEM

PROBLEM TO BE SOLVED: To provide an application development system that can shorten a time for transmission of design information between a system engineer and a programmer and minimize a risk of difference in design concept between the both.SOLUTION: The system includes: a server machine 12; a client machine 16 for development which carries out development; program outline generation software 35 which generates program outline data 56 on receiving design information from the system engineer; application development software 36 which includes a conversion program 58 outputting common output character data 154 for development to the client machine 16 for development and converting a common operation instruction C1' etc., into an operation instruction C1 etc., and generates an application 34 by converting common design information 60 including the common operation instruction C1' etc.; and client software 54 for development which accepts input operation Y that the programmer does based upon the program outline data, and outputs common input character data 156 for development to the server machine 12.
