Abstract:
This article reports an empirical assessment study conducted with 27 subjects intended to verify the effort (time spent), precision, recall, F-Measure of a proposed tool based on a textual approach (ERtext), thereby a study developed for comparative reasons of ERtext with a tool based on graphical approach: thebrModelo. The results are: 1) less effort is associated with the graphical approach and that ERtext, and 2) regarding the model quality, brModelo have similar performances in both approaches. Since the results shows no considerable statistical differences among the two design approaches, we conclude that the usage of a textual approach is feasible, thus ERtext is a good tool alternative in the context of conceptual database modeling.
