Research And Implementation Of A Stroke-oriented Personalized Health Information Services System

Information service is a kind of studying and organizing the users,making the useful information convey to the users and help users solve practical problems. Health information service system is a kind of information service system which is provided for the users of cerebral stroke,and the information service activity is closely combined with the medical activities of the cerebral str oke patients,providing network information service platform of management, analysis, consulting and retrieval in the field of medical and health.The personalized health information service system for the patients of cerebral stroke, which is based on the analysis of the patients personal health data, and provides health knowledge information, consulting information, treatment and other services.In this paper, we take into account all aspects of the traditional relational database, such as that the common machine as a server, data backup and security can not be guaranteed; the cost of the deployment and maintenance is high, and the iteration speed is fast;computing power has bottlenecks, during the peak time, and it is easy to exceed the carrying capacity of traditional database; poor scalability is often unable or difficult to add new equipment to upgrade.Based on the above reasons, and combined with the development of big data technology, computing and its storage capacity are greatly enhanced,also with the emerging technologies of big data computing framework on Hadoop,services technology of restful web,and non relational database,the paper constructs a Hadoop platform of cerebral stroke for the personalized health information service system.First of all, this paper makes a detailed and comprehensive analysis on the technology and correlation theory of the personalized health information service system for cerebral stroke.Through consulting a large amount of literature data, this paper determines the meaning and specific usage scenarios of the personalized health information service system for cerebral stroke.Then the paper introduces the data platform of Hadoop and its ecological circle, restful web service,full-text search engine server Solr,background development framework Jfinal, and mobile development platform Android, which are the key technologies for realization of the personalized health information service system for cerebral stroke.Then, through the understanding of the definition of health information service and the analysis of the possible operation status of the health information service system, the demand analysis of the personalized health information service system of cerebral stroke is given in this paper,to determine the system’s us er and functional requirements in two areas.Next, this paper designs and implements the personalized health information service system of cerebral stroke, and shows the main interface of the system.In this paper, the whole system is divided into four mod ules: personal health data center, personalized health information recommendation subsystem, personal health management mobile applications and personal health information management background. In the construction process of the whole system,this paper ai ms at the specific requirements of personal health data storage,combines with the characteristics of large data frame of Hadoop, making full use of the Hadoop and Hive, Hbase, and these large data technology has been widely used to solve the data element determined, isomorphism, strategic decision of synchronization problem, fast query optimization and database maintenance and upgrade in the field of digital medical treatment now.After, on the basis of personal health data center,the paper constructs the personalized health information recommendation subsystem, personal health mobile application Android,and the corresponding personal health data management platform.In the end, according to the personalized health information service system of cerebral stroke and its problems under the real operating environment,the paper designs and simulates the whole information service system performance and the test of reliability,to verify the research and design in the paper,which can realize the personalized health information service system of cerebral stroke with good performance.
