Applicationof Data Visualization Technology In Educational Information Database

With the development of science and technology,information technology has also been used in the field of education.The number of students is increasing in geometric form.The educational administration system is also becoming more and more complex,and the data in the educational administration system is also increasing.Experienced Web1.0,Web2.0 and mobile Internet technology revolution,Internet of things and big data has become the forefront of the current technology.The rapid development of society,the progress of science and technology,data association becomes more and more closely,the educational teaching,the doctor's diagnosis,the big data era,people's way of life has changed dramatically,big data in educational administration database has also been used more.Alibaba founder Jack Ma once said that the future is not the IT era,but the big data era.The era of big data,how to analyze massive data mining,cloud computing technology,through the analysis of data mining,data,make the data in the database in the form of data visualization display for educators,and through the large data support the deep learning of the students,through the analysis of data visualization technology to display form in the teaching content,to improve the teaching process through the analysis of data visualization,improve the quality of teaching,to solve the problems in the teaching process through educational database.Educational data visualization technology has become the focus of education experts and seniors and the urgent need to address the hot issues.Data visualization teaching database mainly includes teaching database of data collection,data analysis,data filtering,educational teaching,educational data mining,data representation,data modification of educational administration and educational administration data interactive data mining process.Through mining data,data visualization technology is used to display.Data visualization is usually used to display data into charts.The readability of the data in the database is less than that of the table data,and the readability of the table data is less than the readability of the image.The readability of image data is the best,therefore,the data visualization technology of educational administration database becomes very important.At present,the popular data visualization technology in the market mainly includes: Echart,Highcharts,Excel,JfreeChart and other tool components.Based on the data visualization technology is mainly based on JfreeChart detailed analysis and mining administration database,and to display through JfreeChart data visualization technology,the use of content to improve the data visualization technology in teaching in the database.Using data visualization technology,teachers can the students timely understanding,can improve classroom teaching,teaching evaluation,students can self assessment test,find problems,solve problems,and through the data visualization technology used in the database in order to effectively improve the quality of teaching.The visualization of educational administration data can facilitate the decision support of administrators.The implementation of this system is to take the application of data visualization technology of B/S structure in the database,the system is written in Java language,using Mysql database to store data,was developed in MyEclipse 10 environment.The front of the system with Nginx reverse proxy server for debt balance,application server and Tomcat7 server system,released on the Tomcat7 application server,set the load balancing by Nginx Upstream,at the same time to make the Session shared with Memcache cache server,back-end using distributed MySQL database,using the distributed Mysql middleware Mycat distributed database operation,reading write separate table library distributed operation,data visualization technology mainly uses the Java framework Jfree Chart open source technology display.
