Design And Implementation Of Smart Class Management Information System Based On Hybrid Cloud Environment

In recent years,with the development of new technologies such as cloud computing,big data and internet of things,educational informatization has been gradually transferred from a single application system to cloud application.Nowadays,cloud computing has developed to a relatively mature stage,everyone in the school needs a powerful cloud service combined with big data to achieve the purpose of optimizing the allocation of educational resources.At the same time,the cloud service will help the school to achieve precise management,teachers with intelligent teaching and students to gain creative learning."National long-term reform and development plan(2010-2020)" issued by The Ministry of Education clearly demand that regions or schools with conditions should promote the reform of the Class-Selection System of stratified teaching method,and a smart class management information system has been the best solution to solve the problem of class management in the new teaching reform.Under this background,combined with the basic environment of the education cloud platform built by Zhenjiang Education Bureau,and according to the requirements of "Guiding opinions on the construction of smart campus in primary and middle schools in Jiangsu province(Trial)",the implementation of the system in Zhenjiang needs to be customized and developed according to the characteristics of the region.It is gradually perfected and popularized by new technologies such as cloud computing and big data.Finally,the educational big data acquisition platform will be built.The project takes Zhenjiang High School of Jiangsu Province as the demonstration school of the class management information system construction.We analyze the requirement of the system,study the technical standard and the development interface of Zhenjiang education Cloud platform.We combine the characteristics of Alibaba cloud services and Tencent cloud services,design and implement the system.The main work includes the following aspects:(1)Through the investigation of the main users,such as the school administrators and teachers,in addition to understanding the needs of the Class-Selection System of stratified teaching method,we also know the needs of school how to achieve precise management,and teachers how to intelligent teaching,and students how to gain creative learning.Besides this,we also communicate with systems administrator to know the existing information system at school,mainly including one-card-pass system,access control system,Library management system and other systems.Then,we analyze and research on the possibility of system interconnection between those systems and class management information system.(2)Based on hybrid cloud environment,we analyze and research the technical architecture of Zhenjiang Education Bureau's private cloud platform and Public cloud platform,and refer to the Hadoop framework and use many components of the Hadoop ecosystem,such as HDFS Yarn MapReduce Zookeeper Hbase Spark and so on to design and implement the architecture,function modules of smart class management information system.(3)The application and development adopts the J2 EE technology framework,which divides the functions into three parts: Model layer,View layer and Controller layer by using J2 EE technology framework,the view layer use standard HTML,and JS syntax is compatible with different browsers.(4)During the project development,our development team use MyEclipse integrated development environment to develop the application of J2 EE,use SVN for configuration management,use Microsoft Project to do schedule control,through many cases for unit test,coupling test and integrated test to reduce bug as much as possible.(5)At present,the smart class management information system has been deployed on Zhenjiang Education Bureau's private cloud platform,and the system is implemented in Zhenjiang High School of Jiangsu Province,it has realized the interconnection between one-card-pass system in school and "JiKe Examination system" in Alibaba Cloud platform.At the same time,the smart class management information system realizes family and school interconnection function by WeChat.Up till now,the system runs well and has very strong practicability.
