    Evaluación experimental sobre la utilización de patrones de gobierno electrónico
    (2022) Medina, Oscar Carlos; Groppo, Mario Alberto; Marciszack, Marcelo Martín
    En el marco de la Tesis Doctoral “Definición de Patrones a partir de Buenas Prácticas para el desarrollo de sistemas de Gobierno Electrónico”, se realizó un experimento con el objetivo de evaluar si el uso de patrones mejora o no la facilidad de comprensión del modelo conceptual de un sistema de gobierno electrónico real, comparándolo con el uso de descripción narrativa exclusivamente, o en combinación patrones de negocio más descripción narrativa. Este trabajo expone las actividades principales del experimento, planificación, ejecución, análisis e interpretación de resultados, y presenta las conclusiones del mismo en relación a las hipótesis planteadas.

    Systematic mapping of literature on applicable patterns in conceptual modelling of information systems
    (Springer, 2021) Medina, Oscar Carlos; Pérez Cota, Manuel; Damiano, Luis Esteban; Della Mea, Karen; Marciszack, Marcelo Martín
    Abstract. Context: The addition of patterns to the Conceptual Model of Information Systems would allow to optimize the quality level of computer systems. In spite of the fact that there are several studies on the application of patterns in the different phases of software development, since the beginning, these studies have focused on programming rather than analysis and design. Objective: The aim of this study is to carry out a systematic mapping of the field of Software Engineering in an attempt to characterize state-of-the-art patterns that can be applied to Conceptual Modelling, identifying gaps and opportunities for future research. Method: A systematic mapping of existing literature on the topic was performed in order to identify the most important studies on the field. These were then classified and analyzed according to different criteria. We also carried out a subjective assessment highlighting the most important ideas and experiences identified. Results: As a result of systematic mapping, there were found 26 primary studies of interest published between January 1995 and December 2019. In general, these studies are associated with software modelling methodologies which provide empirical evidence of the impact of the use of patterns. Conclusions: In this preliminary study, it was possible to identify the most relevant pattern types that were applied in the Conceptual Modelling of Information Systems. Integrating these types of patterns with existing analysis and design tools is also an important challenge that needs to be addressed in this area.
