Abstract:
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.
