Uma linguagem para a modelagem lógica de Bancos de Dados no brModelo Web

Abstract

The representation of a Database can occur at different levels, namely conceptual, logical, and physical, requiring distinct levels of abstraction to express different aspects of the system in an integrated manner. Considering the importance of logical modeling in this process, this work presents an extension developed for the brModelo Web tool, which enables the development of logical modeling in a descriptive way. Its main objective was the development of a domain-specific language to facilitate the creation of tables and relationships. The adopted methodology involved a bibliographic review, the definition of the proposed language, its implementation in the brModelo Web system, and the evaluation of the tool, carried out with students and project collaborators. The results indicate good acceptance of the proposed approach, highlighting its practical usefulness and the clarity of the language, as well as the preservation of the tool’s original usability, demonstrating the potential of the solution as a complement to the traditional logical modeling process.
