北京理工大学珠海学院2020届本科生毕业设计Design and Implementation of Epidemic Situation AnalysisSystem Based on Elastic Stack Platform-User SubscriptionModuleAbstractWith the epidemic of novel coronavirus (covid-19)in 2019 and the global outbreak,China is the first to face the epidemic and apply effective treatment measures to controlthe spread of infection.Thanks to the rapid development of Internet technology inrecent years and the openness and transparency of China's epidemic data,China hasbecome the first country with a large number of epidemic data resources.In the face oftens of thousands of big data every day,how to effectively collect and use these data tohelp the public or relevant departments to carry out effective anti-epidemic actions hasbecome a question worth thinking about in this epidemic storm.An excellent epidemicanalysis platform can enhance public participation in anti-epidemic activities and senseof security,and help speed up the follow-up process of enterprises returning to workand production.The epidemic situation management system is an information management and displaysystem including server side and web side,which is developed according to the processfollowed by software engineering.First of all,carry on the comprehensive demandanalysis to the epidemic situation management system,then carry on the system designaccording to the demand analysis.The system adopts the design pattern of separationof front and rear ends.As the server-side development uses the Spring Boot framework,the system has a more convenient and good monitoring function in the later stage,andthe upgrade of the system function in the later stage is more expandable.Because thedevelopment of the display side uses the vue framework,the system has lightweightand faster performance.Based on the availability and performance requirements of thesystem,two different data storage analysis solutions,ElasticStack and MySQL,areadopted to deal with different usage scenarios.For data acquisition,the system uses a
