Automatic generation of client-server collaborative Web applications from diagrams

We have designed and implemented Web application generators based on a diagram approach, which is an approach to generating data-intensive Web applications by using diagrams that represent dataflow relationships among Web components. In this paper, we illustrate how to extend the generator systems to generate client-server collaborative Web applications, in which client-side programs collaborate with server-side programs in performing the whole business logic. The client-side programs contribute toward not only reducing the load on Web servers but improving security and session management of the generated application.
