Abstract:
Real-Time applications handling big volumes of Real-Time data with time constraints, such as web-based multimedia applications or Vehicular Cyber-physical Systems, often lead to unpredictable overload problems in Real-Time DataBase Management Systems (RTDBMS) managing them. This is due to frequent Real-Time user transactions, requesting access to Real-Time data, which are characterized by unknown arrival times, unknown workloads and time constraints. In the literature, many software solutions with Quality of Service (QoS) management are proposed to resolve these problems. Although effective, they remain application-dependent regarding Real-Time data and transactions models and QoS requirements. Moreover, no formal or semi-formal models of these solutions or tools are proposed to design them. Therefore, it is not possible to reuse such solutions for Real-Time applications with specific QoS requirements and needing other data and transactions models. To address this issue, we propose a Model Driven Engineering based framework for modeling QoS management solutions in RTDBMS and reusing formal models of well-known solutions. The framework provides a tool and strategic methodology to help users achieve their goals through several strategies that fit their requirements.
