    Extracting class diagram from hidden dependencies in data set
    (Wydawnictwa AGH, 2020) Hnatkowska, Bogumiła; Huzar, Zbigniew; Tuzinkiewicz, Lech
    A conceptual model is a high-level, graphical representation of a specic domain, presenting its key concepts and relationships between them. In particular, these dependencies can be inferred from concepts' instances being a part of big raw data files. The paper aims to propose a method for constructing a conceptual model from data frames encompassed in data files. The result is presented in the form of a class diagram. The method is explained with several examples and verified by a case study in which the real data sets are processed. It can also be applied for checking the quality of a data set.

    Modelowanie konstrukcji obiektowych języka UML z zastosowaniem kolorowanych sieci Petriego
    (Wydawnictwa AGH, 2007) Szmuc, Wojciech
    The paper describes a use of coloured Petri nets in UML object concept modelling. The proposed solution provides a construction of net representing structural view of system. Dynamic entity creation is also supported. Coloured, hierarchical Petri net is an outcome of the algorithm. Size of the net is constant and independent with regard to object creation/destruction. This benefits in applicability of existing tools for building and systematic properties analysis of created model.
