Patterns for web applications

This paper presents the preliminary results achieved in introducing a new formalism into the Web business logic layer. New useful and consistent patterns have been defined to support the modelling phase of web applications. The innovation in the use of patterns is extremely important when concepts like solidity, stability and reuse are crucial for the application design. The proposed patterns are graphically modelled using the Unified Modelling Language and formalized using the Object Constraints Language introduced by IBM. The new patterns are suitable for use in a CASE tool, to help developers build web solutions and eliminate inconsistences often present in natural languages
