Requirements models are used to specify system functionalities from the customer viewpoint and are the starting point of software development. However, most Web engineering approaches do not provide a systematic method to build design models from requirements specification. We propose an approach using model transformations to close this gap. Our transformation rules are defined in the QVT language – a forthcoming OMG standard, which makes automatic model generation possible. This way design is kept consistent with the customer requirements. Categories and Subject Descriptors

this paper a metamodel (i.e. abstract syntax) for the UWE methodology, which could then be joined with metamodels that are/will be defined for other methods. It is defined as a conservative extension of the UML metamodel (UML, 2001). This metamodel provides a precise description of the concepts used to model Web applications and their semantics. Our methodology UWE is based on this metamodel including tool support for the design and for the semi-automatic generation of Web applications. We further define a mapping from the metamodel to the notation (i.e. concrete syntax) used in UWE

There are various web design methodologies and strategies that use different mechanisms and algorithms. However, none of them deals with integrating business rules during the website development process. Business rules, which have been around since ancient times, covers many human needs and their daily life business, and therefore, should be considered in parallel with other design issues.

This paper presents a UML profile for web–based educational applications. The definition of the profile is provided by applying a certain formalism which is based on the metamodeling architecture of the UML language. An example is given throughout the paper for the illustration of an instantiated model based on the profile. 1.

Model driven software engineering (MDSE) is becoming a widely accepted approach for developing complex applications and it is on its way to be one of the most promising paradigms in software engineering. MDSE advocates the use of models as the key artifacts in all phases of the development process, from analysis to design, implementation and testing. The most promising approach to model driven engineering is the Model Driven Architecture (MDA) defined by the Object Management Group (OMG). Applications are modeled at a platform independent level and are transformed to (possibly several) platform specific implementations. Model driven Web engineering (MDWE) is the application of model driven engineering to the domain of Web application development where it might be particularly helpful because of the continuous evolution of Web technologies and platforms. However, most current approaches for MDWE provide only a partial application of the MDA pattern. Further, metamodels and transformations are not always made explicit and metamodels are often too general or do not contain sufficient information for the automatic code generation. Thus, the main goal of this work is the complete application of the MDA pattern to the Web application domain from analysis to the generated implementation, with
