A visual approach to development of web services providers/requestors

Comparison of Two Approaches for Automatic Construction of Web Applications: Annotation Approach and Diagram Approach

“…Based on diagram approach, we designed and implemented a prototype generator called T-Web system which generates Web applications from directed graphs called Web transition diagrams [3,4,5,6,7,8,9]. While we have prototypes to generate CGI programs, JSP/Servlet programs and ASP programs respectively, we may be able to generate applications based on other architecture by replacing part of the generators because diagram approach itself is independent of specific architecture of Web applications.…”

“…The development of such applications, however, requires much cost and experience of developers because of the complexity of security checks and session management, which are unique to Web applications. In order to support development of consistent and secure Web applications, we have designed a number of Web application generators which generate source codes necessary to execute the application [1,2,3,4,5,6,7,8,9]. Web application generators encapsulate the complexity unique to Web applications and make developers concentrate on the business logic of the application.…”

“…And then the generator generates procedural program codes from Web page templates with annotations. The second is diagram approach, which concentrates on data-flow relationships in the application [3,4,5,6,7,8,9]. Developers first compose diagrams which describe overall dataflow relationships among Web components such as Web page templates, server side programs and databases.…”
