Furthermore, the architecture of the recovery system is also presented. To achieve the robustness and the high availability of the embedded real-time database systems, the failure recovery strategy based on real-time logs, checkpoint strategy, reload strategy and the applications recovery in mobile environment are researched on the basis of analyzing the characteristics of data and transactions of the embedded real-time database systems.Īccording to the special needs of embedded applications and the timing constraints of data and transactions in embedded real-time databases, the architecture and the system composition of the embedded real-time database management system which use the main memory databases as the underlying support are presented. The recovery strategy suitable for different demands of applications is critical to the embedded real-time database systems which can be running reliably and effectively in the embedded real-time environment.
