摘要
针对现有医院信息数据存储系统响应延迟高、稳定性不足的问题,提出一种基于分布式架构的新型数据存储系统。该系统采用微服务化设计,将模块化拆分与工作流引擎相结合,实现了数据接收、摄入、校验和调度等流程的自动化与并行处理。同时,引入分布式数字对象仓储与云存储融合机制,支持海量医疗数据的高可靠持久化存储,并有效统一管理多源异构数据。实验结果表明,该系统在稳定性、系统吞吐量与访问延迟等关键性能指标上均优于传统集中式存储方案,能够为大数据环境下医院信息资源的安全、高效与长期存储提供可靠技术支撑。
Aiming at the problems of high response delay and insufficient stability of the existing hospital information data storage system,a new data storage system based on distributed architecture was proposed.The system adopts microservice design,combines modular decomposition with workflow engine,and realizes the automation and parallel processing of data receiving,ingestion,verification and scheduling.At the same time,the integration mechanism of distributed digital object warehousing and cloud storage is introduced to support the highly reliable persistent storage of massive medical data,and effectively manage multi-source heterogeneous data.Experimental results show that the proposed system is superior to the traditional centralized storage scheme in key performance indicators such as stability,system throughput and access delay,which can provide reliable technical support for the security,efficiency and long-term storage of information resources in the hospital big data environment.
