Research ArticleOpen accessPhrase in the titleThinging-Based Conceptual Modeling: Case Study of a Tendering SystemSabah Al-Fedaghi, Esraa HaidarIn computer science, models are made explicit to provide formality and a precise understanding of small, contingent “universes” (e.g., an organization), as constructed from stakeholder requirements. Conceptual modeling is a fundamental discipline in this context whose main concerns are identifying, analyzing and describing the critical concepts of a universe of discourse. In the information systems field, one of the reasons … …Journal of Computer Science, Vol. 16, Issue 4 · 15 Apr 2020 · 7,943 accessesView PDFCite
