A Validation Approach for Ontology-Based Real-time DBMS

Abstract

Real-time DBMS (DataBase Management Systems) are an appropriate storage system under real-time constraints. However real-time DBMS do not implement inference or reasoning mechanisms. Ontologies on the other hand allow these mechanisms by creating formal representations of concepts, properties and relationships between concepts. Traditionally ontologies have been applied to static domains, in the sense that entities represented in these ontologies do not change over time. However objects in real time databases are dynamic; it is possible that an object changes their value along time. To overcome this limitation, in this paper, we propose a Feedback Control Scheduling Architecture for Real-Time Ontology that develops the temporal aspect within an ontology in the real time databases and that guarantee of Quality of Service (QoS) for real-time DBMS under unpredictable workloads.
