This paper investigates the effect of construct redundancy on readers' understanding of conceptual models. Conceptual models play a crucial role in understanding the domain related to information system development. The clarity of such models can be compromised if they are constructed using a conceptual modelling grammar exhibiting construct redundancy where one real-world phenomenon maps to two or more grammar constructs. With two empirical studies on solving domain-related problems using Unified Modeling Language (UML) class diagrams as conceptual domain models, it was found that when construct redundancy is present at different strengths, then the effect of the redundancy on the understanding of a model depends on the modeling knowledge of the reader. Novice readers with minimal modeling knowledge find models difficult to interpret when a strong level of redundancy caused by distinct construct redundancy exists. However, when the models have a weak level of redundancy then these readers find them easier to understand compared to models without redundancy. In contrast, trained readers are indifferent to a weak level of redundancy in a model.

Dit Intelkam Polda Riau menyelenggarakan fungsi untuk memberikan pelayanan kepada masyarakat yaitu pelayanan pengurusan Surat Keterangan Catatan Kepolisian (SKCK). Pengurusan SKCK ini dilakukan dengan mendatangi langsung kantor Dit Intelkam Polda Riau. Proses pembuatan SKCK pada Dit Intelkam Polda Riau, saat ini telah menggunakan database dalam penyimpanan datanya. Namun kelemahannya yaitu data lama pemohon akan hilang apabila belum dilakukannya perpanjangan oleh pemohon sebelum masa berlakunya habis. Hal ini disebabkan karena data lama yang tertimpa oleh data baru yang di-input-kan ke database.Selain itu SKCK yang lama juga tidak mempunyai sistem keamanan sehingga data SKCK tersebut dapat disalahgunakan oleh pihak yang tidak bertanggung jawab. Permohonan penerbitan SKCK pada Dit Intelkam Polda Riau bisa mencapai 200 penerbitan perharinya dengan kategori high section yaitu jumlah bagian dengan penerbitan tertinggi dalam satu hari. Sedangkan untuk pengurusan dalam pertahun dari Tahun 2016 pengurusan bisa mencapai sebanyak 30.000 lembar.Sistem ini menggunakan keamanan barcode, dimana barcode tersebut mempunyai informasi didalamnya yaitu: nama, nomor NIK, tujuan dan masa berlaku SKCK. Metode pengembangan yang digunakan dalam penelitian ini yaitu System Development Life Cycle Model Waterfall yang menggunakan tiga buah diagram Unified Modeling Language (UML), yaitu: usecasediagram, activity diagram dan sequence diagramserta memanfaatkan penggunaan ERD dalam pembuatan database. Pembangunan sistem dilakukan menggunakan beberapa aplikasi pendukung yaitu: PHP dan MySQL,Sublime Text 3, Javascript, dan HTML.Hasil dari penelitian ini dapat memberikan keamanan terhadap data SKCK pemohon dan dapat mempermudah Admin Kepolisian Daerah dalam proses pembuatan surat SKCK

Object-Role Modeling (ORM) is an approach for modeling and querying information at the conceptual level, and for transforming ORM models and queries to or from other representations. Unlike attribute-based approaches such as Entity-Relationship (ER) modeling and class modeling within the Unified Modeling Language (UML), ORM is fact-oriented, where all facts and rules are modeled in terms of natural sentences easily understood and validated by nontechnical business users. ORM’s modeling procedure facilitates validation by verbalization and population with concrete examples. ORM’s graphical notation is far more expressive than that of ER diagrams or UML class diagrams, and its attribute-free nature makes it more stable and adaptable to changing business requirements. This article explains the fundamentals of ORM, illustrates some of its advantages as a data modeling approach, and outlines some recent research to extend ORM, with special attention to mappings to deductive databases.

Object Role Modeling

This chapter provides metamodels for some of the main database modeling notations used in industry. Two Entity Relationship (ER) notations (Information Engineering and Barker ER) are examined in detail, as well as Object Role Modeling (ORM) conceptual schema diagrams. The discussion of optionality, cardinality and multiplicity is widened to include Unified Modeling Language (UML) class diagrams. Issues addressed in the metamodel analysis include the normalization impact of non-derived constraints on derived associations, the influence of orthogonality on language transparency, and trade-offs between simplicity and expressibility. To facilitate comparison, the same modeling notation is used to display each metamodel. For this purpose, ORM is used because of its greater expressibility and clarity.
