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.

¡@¡@There is a general agreement that information system (IS) is one of the effective solutions to help enterprises dealing with the challenge in today¡¦s dynamic environment. In response to the changing business environment, the need for a system with flexibility, high quality, and low cost has increased dramatically. Besides, end users more and more rely on IT (information technologies) or IS for their daily life or work. Therefore, how to attain high software throughput would be highly sought constantly. An idea of reusing previously developed modules, packages, components, software development methodologies, analysis data and test information has been attracting as a keystone to improve software productivity. This approach was called component-based development (CBD) or component-based software engineering (CBSE) and is becoming the main stream of software development. ¡@¡@Various CBD approaches, tools, and techniques were proposed in the literature, however the research on the integration of the above into an environment to enhance the system development is virtually lacking. Therefore, we proposed a framework of application generator, which integrates above approaches and concepts into a collaborative mechanism. Otherwise, we proposed a methodology based on our generator for end users to translate the business models or user requirements into the specification and construct application more efficient. Finally, we apply this methodology to a real-world case and generate the application by the generator in order to verify the feasibility.
