Abstract
The relationship between Description Logic (DL) and database is quite close. Indeed, the needs for the building of the systems that can manage both the database and the knowledge representation are really necessary. A description-logic based on the knowledge representation system not only allows the knowledge management, but also provides a standard framework which is considered to be very close to the language used to represent the Entity-Relationship model (ER model). On the other hand, the temporal ER model is used to model the time aspects of the conceptual database schema. Thus, the problem of the use of description logic to express temporal ER models is really useful for modeling the conceptual data models. Based on the temporal DL, Alessandro Artale et al. (2011) presented temporal ER schemas and integrity constraints in the form of complex inclusion dependencies. The paper approaches the representation method of Alessandro Artale and proposes mapping multi-valued attributes in the temporal ER model to DL. Description logic application in TimeER modeling
