Design of Hybrid Application Based on GraphQL for Efficient Query for PHR

As the use of smartphones increases, the use of mobile applications also increases. Similarly, the importance of preventing and managing chronic diseases has increased as life expectancy has increased. As a result, medical records that are generated in hospitals, and the life logs that occur in daily life become more important. Life logs are collected through various channels using sensors, and it is necessary to provide a service capable of effectively querying and collecting a large amount of collected personal health records (PHR). In this paper, we have designed a hybrid application that can show clients’ PHR efficiently using GraphQL and React Native.
