Component-based software is finally taking off in a big way and component-based application generators have been championed because they can be used to shorten a system¡¦s development cycle and therefore lower its development costs. Component-based application generators are standardardized building blocks that can be used to assemble, rather that develop, information systems (IS). This paper presents a component-based application generator in the restaurant food ordering setting and a requirement modeling methodology for IS construction based on the generator presented. A prototype was assembled using the generator and methodology presented to illustrate the concepts and application. With this approach, system developers or end users can more easily build, modify and maintain their applications.
