UML-based design of network processors applications

Abstract. Web application development is among the most rapidly changing areas in nowadays software industry. Both problem space and solution technologies affect the cost-effectiveness of such applications whose business pressures of cost, quality and time-to-market are among the most extreme. Model-driven architectures (MDA) separate the application logic from the underlying platform technology and represent this logic with precise semantic models. Web application development therefore has potentially the most to gain from adopting such techniques and models that can offer a greater return on development time and quality factors than traditional approaches. In this paper we describe a systematic approach to Model-driven development of data intensive web applications meant as hybrid between hypermedia and information systems. After first defining a suitably UML profile, the paper explains how data-intensive Web applications can be systematically and rigorously modeled using UML. It then describes how to perform model transformations to obtain a platform-specific model expressed by means of the Conallen’s profile and in turn how a suitable platform can be traceably generated. 1

Model-Driven Software Development (MDSD) is becoming a widely accepted approach for developing complex distributed applications. MDSD advocates the use of models as the key artifacts in all phases of development, from system specification and analysis, to design and implementation. Each

Abstract. Model Driven Engineering (MDE) is increasingly gaining acceptance in the development of Web Applications as a mean to leverage abstraction and render business logic resilient to technological changes. This paper describes the beContent project with its modeling languages and tools, which aims at the auto-mated generation of rich Web applications. 1
