A semantics-based validation approach for enhancing QoS in distributed real-time DBMS

Distributed real-time database management systems (DRTDBMS) are essential for critical applications such as financial trading and healthcare, where timely processing is vital.Quality of service (QoS) approaches, like the distributed feedback control scheduling (DFCS) architecture, are favoured for improving DRTDBMS performance.However, transactions scheduling remains a challenge in such systems, impacting user's experience.Recently, the advanced earliest deadline first based on transactions aggregation links and data semantic links (AEDF-TAL-DSL) protocol emerged as a scheduling solution in a centralised real-time context.This paper focuses on exploring the adaptability of the AEDF-TAL-DSL protocol to the DFCS architecture, offering a significant opportunity to optimise DRTDBMS performance.The novelty of our approach is to enable advanced transaction scheduling while considering transaction aggregation links and data semantic links aiming to
