| The Meridian II project is a key national construction project and is listed as one of the top ten priority projects supported by the National Development and Reform Commission.The solar-interplanetary subsystem of the Meridian II project can achieve all-weather,full dynamic tracking and monitoring from the solar surface to near-Earth space,and the Min Antu Interplanetary Scintillation Telescope is a key component to achieve this goal,which can provide accurate observation data.In order to easily classify and query these sources,and thus generate the daily observation plan of the telescope,a database of the millions of target sources that can be observed by the Min Antu Interplanetary Scintillation Telescope(MST)is needed.management.The system in this thesis can display the collected radio sources to the client,so that the user can login to the system and directly view the catalog and related information of the Min Antu Interplanetary Scintillation Telescope at any given time by filtering the criteria,and then plan the daily observing tasks of the telescope.The system is developed through a one-stop Spring Boot framework,which not only allows the application to be built quickly,reducing development time and costs,but also enables the automatic configuration of the various components required for the application.The front-end framework of the system uses responsive Bootstrap,which enables the system to be displayed well on different devices.And the system uses Echart,a data visualization tool,which can make the data more intuitive and easy to understand.The system is researched and applied in the performance optimization of My SQL database,so as to improve the response speed and stability of the system and bring a better experience for users.Specifically,Druid connection pool is used to manage and maintain database connections,followed by combining My SQL slow query log and mysqldumpslow to analyze SQL statements to find out time-consuming operations and optimize them,and finally,query optimization is used to improve the performance and responsiveness of the database system.In conclusion,the system can be made more efficient,reliable and easy to manage through the rational use of various technical tools.In order to verify the functional and performance indicators of the optimized platform,the system was tested.In the functional tests,the modules and interfaces of the platform were examined for comprehensive coverage according to the pre-designed test cases,and the platform was found to be able to operate normally and meet the design requirements.The test results show that the optimized system has significantly improved in terms of stability,scalability and query speed,and basically meets expectations. |
