| With the rapid development of information technology,informatization has become an essential element for the development of all walks of life.The informatization construction of Chinese universities started in the mid-1990 s.After more than 20 years of construction and development,some remarkable achievements have been made in infrastructure construction,educational and teaching resources construction,and digital campus education and management in colleges and universities.The advantages of service informatization and the role of innovation have also gradually emerged.However,due to multi-campus universities,increasing students base,and uncertainties in the investment of information construction,the digital campus construction in colleges and universities has encountered some bottleneck problems.These problems are concentrated in gaps between information centers,which is difficult to share data resources;business systems are closed and isolated,which means systems are difficult to integrate effectively;client authentication has many ways,but lacks of personalized and unified portals;development technology is backward and cannot meet the needs of users of multiple terminal devices;accessible networks are usually limited to the campus network of the school that the use environment is limited.If the business system is completely discarded and reconstructed to solve these bottleneck problems,the capital and labor costs are too high and the cycle is too long.This project aims at these bottleneck problems.The project takes the actual situation of a certain university’s existing information system in Guangxi as an example,proposes to integrate data by using web services and web crawler technologies,combining the ThinkPHP and Vue development technology with the user authentication data interface provided by the easy class open platform without changing the existing business systems to develop a multi-terminal university information portal system based on MVVM front-end and MC back-end.In the course of research and implementation,this subject has created thefollowing technological innovations:(1)A new campus heterogeneous system and data integration solution is proposed,which does not require reconstruction of the original system,and the cost is low;and the portal system is completely disconnected from the database of the business system and it has higher security.(2)The portal system adopts the latest framework technology that can adapt itself to terminals under different operating system environments such as mobile phones,tablets,and PCs.(3)The portal system adopts the data interface based on E-Class open platform.Users can access the data of multiple business systems and achieve multiple logins with single point in school as long as they use E-Class.(4)The usage of the data interface of the E-Class open platform can not only ensure users who are certain students or teachers in the University of G,but also ensure the safety of data,which break the dependence of campus information on campus information of past protection levels.(5)The usage of data caching technology can effectively prevent the system from crashing when an individual business system fails or crashes.The portal system can access the cached data in the business system to achieve offline operations in such situation.The portal system was successfully implemented and operated stably in the certain university in Guangxi.It was awarded a national award by the Ministry of Education,obtained software copyright registration and got recognized by the business community. |
