Abstract: In this thesis, we present an abstract meta-model for model driven development of web applications targeting multiple platforms. We review the existing technologies and the related work in order to obtain a list of requirements for such an abstract model. The abstract model is built by extending an existing UML-based model for web applications. We demonstrate that it is possible to map this abstract model to more than one specific development platform by providing transformations for these mappings. We also lay out the general outline of a model-driven process based on the proposed abstract model. The abstract model and the model-driven process are supported by a set of tools, case studies and a visual modeling notation. Model-driven techniques have been used in the area of web development to a great extent. Most of the existing approaches are tuned toward specific platforms or develop only certain parts of web applications. These approaches generally use meta-models adapted to their targeted platforms. In order to flexibly target multiple platforms, the level of abstraction of the meta-model must be raised. Such a meta-model must allow the description of relevant features of web applications independently from the specificities of specific platforms. Additionally, transformations mapping from abstract to specific web descriptions must be expressible in a flexible way. In this thesis, we propose such an abstract meta-model. Mappings that transform abstract models to specific platforms are also presented. Different benefits can be foreseen from this approach. By relieving developers from low-level platform-specific related design, the approach has the potential to shift the development task to issues related to business needs. Another benefit is shortened development time. This could help web developers to overcome the problem of schedule delays, which is recognized as one of the top five most-cited problems with large-scale web systems. The approach is specifically suitable for information-intensive web-based systems. These applications typically involve large data stores accessed through a web interface. A distinctive aspect of this approach is its use of a specification of the data mapping as part of its high-level input. More importantly, the common features required to process data and communicate data objects between different layers and components are targeted.
