Design And Implementation Of Real-Time In Embedded Database Management System

The embedded real-time database system is a progressive database management technology that stores, organizes, and manages a large amount of data for mobile equipment and embedded equipment in real time.This thesis first outlines the roadmap, products, and technologies of embedded systems and real-time systems and describes the key technologies achieved in embedded real-time systems. Then, it focuses on the development of real-time management modules in the following aspects: 1) Memory database technology, which achieves all-type fault recovery on data management modules at the bottom layer, thus improving data processing performance and reliability. 2) Real-time transaction manager, which is designed and implemented, based on the analysis of the deadlines for data and transactions, data processing capability, transactions scheduling, and transactions admission.Finally, this thesis demonstrates information about the tests for verifying the real-time feature and the reliability in terms of system performance and system function.
