Design And Implementation Of An Intensive Home-School Network Interactive System

With social development and progress in information technology,home-school communication,as a critical section in traditional education and teaching process,also plays an important role in education informatization process.In an early stage,telecom companies everywhere successively invested and built home-school network interactive systems.However,as time goes by,a lot of issues have been found with these systems,such as lack of maintenance,obsolete technology,poor scalability and lack of information security protection measures.Meanwhile,these systems are built according to inconsistent standards,resources cannot be shared among systems,data regarding operations is difficult to be collected,and the Group Corporation cannot offer sales guidance.In view of all of the said factors,it is difficult for these systems to adapt to current fierce competition environment.Therefore,it is especially important to build a set of more efficient,more convenient and more regulated home-school network interactive system relying on advantages in information and communications technology and resources and by means of such technologies as mobile internet,internet of things and cloud computing.In this article,through research and analysis on status quo and development trend of home-school interactive systems both at home and abroad and based on actual flow of home-school communication in China,an intensive home-school network interactive system was designed and implemented.Firstly,analysis was conducted on the functional and non-functional demands of the system through research and analysis on existing home-school interactive systems and in combination with actual survey regarding home-school communication.Secondly,general design of the system was made based on demand analysis.During the design process,as per non-functional demands such as scalability and security,three-layer optimized expansion architecture was used for the system and dual-link redundancy design was adopted for the network topology.Following design of functional modules of the system based on SOA concept,system design from concept model to database table was completed.Thirdly,detailed design and implementation of the system was conducted.During the process,technical selection was conducted,technology and tools used for development were determined,and description was made to the design and implementation of some major functional modules of the system.In detailed design,it was determined that Java and.NET programming were used for developing the system,SQLServer database cluster was used to store data,front-end and subsystems relating to user operation were developed and implemented with Spring,SpringMVC and MyBatis framework,and subsystems relating to back-end data processing was developed and implemented with.NET.Cache and array systems were introduced to improve performance and availability.Finally,overall test was conducted on the system as implemented.Before the test,system deployment and operating environment were determined,and functional test and performance test were conducted on the functions as implemented.Functional test was to ensure that the system was available and practical while performance test was to ensure that the system was safe,reliable and stable.Taking the status quo of China Telecom home-school interactive system as the subject,a set of more efficient,more convenient and more regulated home-school network interactive system was developed by researching deficiencies of existing systems in terms of regular building,management and maintenance,scalability,information security and resource management and relying on advantages in information communications technology and resources.From the point of view of teachers,the system was designed according to users’use habit,thereby lowering the use threshold for users,improving work efficiency of teachers and allowing them to more focus on teaching,and raising the satisfaction and education concept of students’ parents.The system was designed to meet technical specifications of China Telecom and satisfy business demands,which means the research objective was met.Following going online,the system has offered service to 6 million teachers and students in 30,000 primary and secondary schools in 22 provinces,municipalities and autonomous regions throughout China,and is now running normally.
