The paper faces the problem of simplifying the development of web applications, which have separated resources (the client and the server side) and must deal with multiple user accounts. We propose a model-driven approach that factors out such web-specific aspects and allows the developer to concentrate on the main functionality of the application. In particular, models are used as memory abstraction, which is transparently synchronized between the client and the server. The two main benefits of the proposed approach are 1) the assumption just one target PC and 2) the ability to use the same code base for both desktop and web-based applications.
