“…This study is mainly divided into 3 sub-studies (SS3.1, SS3.2, and SS3.3). The SS3.1 compiles the work of Cal'I et al and D. Calvanese [21]- [26], SS3.2 collected the work of Maraee and Balaban [27]- [32], and SS3.3 presented the work of Efiizoni et al [33]. The SS3.4 compiles the work of Abdul et al [34]- [36].…”

“…In this section, we first define our model of an objectoriented database. Then we formalize it using the description language proposed in (Efrizoni et al, 2010). An object-oriented data model is a collection of classes and instances of these classes.…”
Section: Element Of Object-oriented Data Model Formalizationmentioning
This paper proposes a Description Logics based data model of a real-time object-oriented database. It allows the modeling of structural and behavioral aspects related to the objects in a real-time database. This model provides designers a data model where they can specify both temporal aspects of data and timing constraints on transactions as well as concurrency control mechanisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
