Uso de componentes na programação: estudo experimental com o framework OSGi

Abstract

There are a number of difficulties in the modularization of applications. Such difficulties are found in both the survey of features such as the construction itself, as well as in designing a system so that its modules are loosely coupled, have high cohesion, be dynamic and flexible. This paper discusses the development of component-based software, through a literature review on how to define modules and components in the perception of the system and its representation in UML diagrams. The paper also addresses questions about the architecture of the OSGi framework, which has three levels of use: Modularization, and life cycle services. For each level is a prototype to validate the functionality. On top of these prototypes are presented scripts tests.
