军人健康档案数据库存储模型的设计与优化

摘要

Objective To store and use the military electronic health record ( EHR) data effectively , and to improve the flexibility, scalability, and statistical query performance of data storage .Methods The military EHR data access patterns were analyzed,a military EHR storage model using MongoDB document database was designed ,and the storage model was optimized by storing the whole document and the reduced summary document separately .Results The storage model was used in the military EHR system , which can meet the demands of document query and statistical query at the same time . The optimized model improves the statistical query performance without losing scalability .Conclusion This model can meet the daily needs of the EHR system and is of practical application value.%目的 高效存储和利用军人健康档案数据,提高数据存储的灵活性、可扩展性和统计查询性能.方法 分析总结军人健康档案的数据访问模式,利用MongoDB文档数据库设计数据存储模型,采用将全部文档和缩减摘要文档分别存储的方式进行模型优化,提高统计查询性能.结果 设计的存储模型可同时满足文档查询与统计的功能需求,已应用于军人健康档案系统.优化后的存储模型有效地提升了统计查询性能,具有较好的扩展性.结论 所设计的存储模型可满足健康档案系统的日常使用需求,具有实际应用价值.
