Design and Application of Multi-layer Heterogeneous Data Management Architecture for Space Experiment Command And Display System

Aiming at the command and display system's original data traceability, historical data availability, real-time data high reliability, and heterogeneous environment adaptable command display data management requirements, a multi-layer heterogeneous data management architecture is proposed. The architecture includes a data unstructured persistence layer, a structured persistence layer, a structured cache layer and a localized cache layer. Multiple data management layers can be flexibly combined to provide services according to the usage requirements and resource conditions of the command and display system.
