O Uso do Framework NFR no Projeto de Banco de Dados

Distributed database design is a complex process that involves a set of distinct aspects for the accomplishment of an adequate data distribution (Buretta 1997). Many of these aspects correspond to non functional requirements (quality properties or systems restrictions), for example, availability, costs and performance, that are abstract questions. Non functional requirements are normally not explored in distributed databases design phases, giving a little contribution to the distribution process. This article aims to represent non functional requirements in the initial phases of distributed database design through the integration of strategies proposed by Requirements Engineering area. This work emphasizes the use of Framework NFR (Chung et al. 2000) and makes an extension of its non functional requirements catalogues in order to integrate the major aspects related with data distribution.
