Modularization of variabilities from software product lines of web information systems (in Portuguese)

This paper presents an industrial experience of design pattern application for the modularization of variabilities from software product lines of web information systems. These web systems were developed at the Superintendencia de Informatica (SINFO) from Federal University of Rio Grande do Norte (UFRN). The work describes details about the adoption and composition of traditional design patterns to the modularization of variabilities (optional, alternative and or-feature) that are usually used in web information systems. Furthermore, it also reports some usage scenarios of the conditional execution annotative technique in the implementation of fine-grained variabilities, which are not adequately implemented using traditional design patterns.
