Since the reform and development, with the update and development of my country’s teaching reform, the current teaching level and learning environment have changed a lot than before. How to use the existing teaching content, improves the efficiency of education and teaching through the platform of online education, becomes the top priority facing educators and teaching workers today. The development direction of technology in today’s society, more and more relying on the form of network and computer, in this case, creating multimedia teaching relying on network and computer has become a direction of educational development . Different from traditional teaching methods, online teaching has two distinct characteristics of its own. First of all, it fully mobilizes students’ enthusiasm for learning, and students also like to use new things and new methods to learn. The interaction between teachers and students can be more convenient and efficient than traditional teaching feedback. Secondly, through the computer and the Internet, the original time and space constraints are relieved, and an efficient learning environment is provided for students. Online teaching has established a new teaching mode, which puts forward different requirements for teachers and students . For teachers, teachers are responsible for the conception, design, and later revision and maintenance of network courseware. In this way, the teacher goes from being a complete master of teaching to a supporter of helping students learn. For students, students have changed from passive learning in the past to active learning, which improves the curiosity of knowledge and other forms of combined learners, and gives full play to the subjective initiative of students; these changes are the continuous innovation in the teaching design and development of online courses, and the education and teaching management system should be designed according to the new learning and teaching environment. The role of information technology in human life cannot be replaced; however, in the late 1950s after the invention of the computer, information technology was combined with the education and teaching management system . At present, the so-called information management system usually refers to the computer as a tool for the collection, storage, processing, and query of data information. It is applied to the “man-machine system” of teaching and educational management organizations.
2. Literature Review
Some educational institutions and laboratories analyze the learning characteristics of students based on the online behavior data of students in the educational system. For example, Kim, J. explores students’ online learning data through data mining technology, so as to discover the relevant factors that lead to students dropping out of school . Pavlicheva, E. N. conducted correlation analysis on students’ consumption in Central South University and established a correlation model. According to the strength of encounter correlation, a social network is constructed to discover students’ social relations . Mm, A. first builds a student portrait feature database, then builds a k-nearest neighbor regression prediction model based on student stratification, obtains the k-nearest senior students to the student to be predicted, uses the performance of the senior students to train the decision tree model, and finally predicts the performance of freshmen . Zosimovych, N. constructs student behavior trajectory based on data such as Wi-Fi usage records and campus card usage records, and combines the concept of similarity in statistics to quantify the similarity of two groups of data trends of each student, so as to screen out students with greater behavioral changes, reminding the college to pay attention . Abdelal, Q. field trips to Vincent University, University of Southern Indiana, Indiana State University, Butler University, and Eastern Illinois University, analyzing the practical application of information technology in student information management, discussing its practical aspects, in summary of the paper written: The application of information technology to student information management is a popular trend, and we have not paid enough attention to it for many years . Halder, B. combining the current cloud sharing concept puts forward the cloud cooperative student information management concept: student information management and information technology have the opportunity to collaborate to improve student satisfaction and attendance, and to assist institutions in complying with federal education regulations .
With the continuous increase of teaching information and the gradual diversification of teaching information needs, the school’s existing educational information platform has been unable to meet the needs of teachers and students. With insufficient utilization of information sharing, lack of due cross-over of information resources, coupled with excessive human and financial resources spent by schools in maintaining and updating previous platforms, it has resulted in a waste of teaching resources to a large extent. As an emerging technology, cloud computing can use the network to integrate different computers to form a super-large platform and share the computing, data, storage, and other resources of the computer in an all-round way. The author designs an educational information management platform based on cloud computing technology; it provides a new way to solve the existing problems of teaching resources management in schools.

The virtual resource pool can perform virtual management and unified scheduling of servers, storage, databases, and networks. The physical resource pool includes servers, network devices, storage devices, and databases . (2)Cloud computing design
The educational information management platform is implemented based on cloud computing technology, the author uses the Hadoop cloud framework, and MapReduce and HFDS technologies are responsible for efficient processing of massive data information. In the operation using the MapReduce programming model, new intermediate values can be generated without changing the original information data, so the Map operation has strong parallel computing capabilities. HDFS is a key cloud computing technology used in the author’s design. As a distributed file system, it forms a typical master-slave structure, including the NameNode master node and multiple DataNode slave nodes . In general, HDFS can name information files, and cloud users can then save relevant information to HDFS files in the namespace, or divide the information data into multiple content blocks, which are stored in different DataNode nodes. Figure 3 is an architecture diagram of HDFS, and Figure 4 is an architecture diagram of education information cloud computing based on HDFS technology. (3)Platform function module
The education information management platform based on cloud computing technology is mainly for the collection, management, retrieval, and application of education information; the functional modules are designed as follows: (1)System setting function
In this platform application, administrators can set system titles, columns, layouts, and specific pages, as well as custom management metadata and class library management. (2)User management function
In the design of this function, it is necessary to manage basic information such as user name, password, and department, and divide the different application user roles of the platform, and design the corresponding user platform management authority level, including uploading, downloading, commenting, status display, and information review. (3)System column navigation
The modular design is implemented in the platform, and cloud users can customize the display design for all levels of the platform. When designing teaching courses, you can refer to the subject classification method, first-level disciplines correspond to multiple second-level disciplines, and each second-level discipline can be based on different professional courses of users, add the corresponding course resources . (4)Resource management
Responsible for creating, modifying, and deleting categories, including videos, e-books, e-learning plans, high-quality courses, and other resources in the information category management, can upload, modify, delete, review, and publish related resources, as well as add and publish specific course information title, introduction, attachments, pictures, etc. and display them dynamically. (5)Search within the site
The platform can also meet the requirements of cloud users to input corresponding keywords in the operation, as well as diversified search forms of majors, courses, disciplines, and teachers, so as to facilitate cloud users to quickly query the required teaching information. (6)One-stop personalized service
The platform can realize the integration of the digital campus platform with the education information management platform, uniformly authenticate the campus identity, and customize the personalized page content according to the specific authority assignment, including courseware, audio, courses, and other information resources; cloud users who have not successfully logged in to the platform only have the right to browse the public information of the platform . (7)Resource cloud service
The education information management platform can not only realize the construction and management of teaching resources for cloud users but also realize the connection of resources between platforms at different levels of schools, provinces, and countries, so as to satisfy users’ resource sharing in platform applications and realize the sharing of teaching resources, public cloud, and private cloud.
3.3. System Database Design
In educational information management system platform, based on the B/S platform architecture, it can meet the operational needs of teachers, students, and platform administrators. The system is based on Linux operation serve, and uses Web server to establish SQL Server database, which is designed in combination with the functional modules of the platform; the database relationship table to be created includes users, departments, teachers, courses, and teaching resources . (1)Operating the database
In the design of the educational information management platform, JDBC provides a set of Java APIs for database operations, and the database classes and interfaces are implemented by the Java programming language and achieve cross-platform technical characteristics; the operation steps are as follows: (1)Complete the successful loading of the database Class.forName driver(2)It is necessary to establish the corresponding education information database connection, edit the database name String dbuser = “sa”(3)Establish a Statement object to be responsible for the corresponding operations on the education information management platform database(4)The database query returns the result set ResultSet object(5)Process the result set ResultSet object(2)Business Process
When designing the cloud computing education information management platform, it is necessary to comprehensively consider the roles of cloud users, the level of authority, and the operation and management of information resources; three types of users are divided, including administrators, auditors, and users.
The administrator is mainly responsible for the professional management of the educational information of the whole school, has the right to authorize the auditor of a certain department, and manages and maintains the educational information resources as a whole.
The auditor is responsible for the template management of educational information, the establishment of a professional resource database, and the approval of professional data resource information, including the functions of uploading, modifying, and deleting information.
Users can establish educational information management websites and establish personalized personal operation service centers to extract data to meet cloud user applications. Figure 5 shows the business process of the educational information platform. (3)Network transmission delay
In order to overcome the influence of dynamic changes of the network on data transmission, network monitoring technology is introduced, and real-time monitoring is used to lay a good foundation for intelligent transmission control, adding timestamps at the protocol layer to monitor network latency, adding two fields to each packet, and recording the last received timestamp (LRT) and the current sent timestamp (CST) . After receiving the packet, the receiving end calculates the local packet sending delay according to the LRT and SCT of the packet. At the same time, according to the last time stamp (LST) that the receiving end has saved and the time when the message is currently received, subtract the processing delay of the peer end to obtain the processing delay of the packet in the network.
When -end replies to , it:
When end receives the message from end , its local:
And its current time is:
At this time, the two-way delay of packet sending can be calculated as:
