A source program is generated by 11 (step 114).

As described above, the application generation program stores the source program template as a resource. This source program template is a source program template written in Java language, and is composed of a plurality of class definition parts. Also, each class definition part is a variable definition part,
It consists of a constructor definition part and a method definition part.

FIG. 10 is a diagram showing an example of the source program template. FIG. 10 shows a class definition portion for accessing the database and displaying the acquired data as text on the database inquiry screen. The variable definition portion has a portion described as "% s" or "% d". The portion described as "% s" or "% d" is a portion into which various data set by the first user is inserted. Further, "% s" indicates a portion where character type data is inserted, and "% d" indicates a portion where integer type data is inserted. In the second half of the line labeled "% s" or "% d", the data ID composed of "@" and a four-character number is commented out. This data ID is used to identify each of the various data set by the first user, and is individually associated with each set data.
