Possibilities of using IDEF1X diagrams in data model

U ovom radu opisane su baze podataka odnosno definicije osnovnih pojmova baze podataka, modela podataka i modeliranja podataka te njihove funkcije i način na koji se upotrebljavaju u praksi. Spominje se modeliranje podataka bilo to konceptualno, logičko ili fizičko. Koncetracija je na usporedbi IDEF1X i Chenovog modela podataka te njihovim mogućnostima i semantičkim ograničenjima koja utječu na samo modeliranje podataka. Ukazuje se i na razlike između IDEF1X i Chen modela podataka. Također se prikazuju i opisuju IDEF1X i Chenov grafički prikaz podataka te se unutar poglavlja opisuju različite mogućnosti koje utječu na modeliranje i funkcionalnost dijagrama.In this paper, the databases are described by defining the basic concepts of database, data model and data modeling, their function and the way they are used in practice. The modeling of data is mentioned conceptually, logically or physically. Concerns are compared to IDEF1X and Chen's data model and their capabilities and semantic constraints that affect data modeling. It points to differences between the IDEF1X and Chen data models. They also show and describe the IDEF1X and Chen graphical data view, and within the chapters they describe different possibilities that affect modeling and diagram functionality
