1. An application development support system, stored in a memory, that generates source code of a Web application program operating on an application server, the application development support system comprising: a dictionary table that uses identification information on one or more input/output items displayed on a screen during execution of the Web application program as a key to retain, as dictionary data, information made up of initial values of one or more parameters of a parts object having at least information on a display name showing text of a label control of the input/output item and information about an input/output control displayed to carry out input or output of the input/output item; a code generator that constructs the Web application program by invoking the parts object for displaying each of the input/output items on the screen and generates the source code of the constructed Web application program, a schema acquisition unit that acquires information about a configuration of each column of a business database by reading schema information on the business database accessed by the Web application program on the application server; and a mapping generator that generates mapping information about mapping between identification information on the parts object and the identification information on the input/output item and registers the dictionary data by setting identification information on each of the columns of the business database as the identification information on the input/output item in the dictionary table, wherein when invoked to display a corresponding input/output item on the screen during execution of the Web application program on the application server, the parts object acquires the identification information on the input/output item from the mapping information based on the identification information on the parts object, uses the acquired identification information on the input/output item as the key to acquire information on part or all of the parameters of the parts object from the dictionary table, and based on the acquired parameters, displays the input/output item.

The application development support system according to claim 1 , wherein the parts object performs display control such that the label control is displayed in combination with a specified type of the input/output control or the label control and/or the input/output control is not displayed during execution of the Web application program on the application server, and when generating the source code of the Web application program, the code generator generates the source code such that the parts object is invoked by specifying a predetermined initial value identifying contents of the display control.
