Design And Implementation Of Scheduling System Based On LNMP

With the advent of the "Internet +" era,traditional industries rely on the Internet and have developed better.Compared with the traditional education industry,the scale of online education is also increasing year by year.In order to give students better service who are learning live courses online,they will be equipped with class teachers to promptly solve the difficulties encountered by students in learning.Therefore,it is crucial to improve the efficiency of the class teacher assignment and the quality of the service of the class teacher during the live broadcast.This scheduling system is developed to further control the working hours and the number of service of the class teacher during the live broadcast to improve the enthusiasm and efficiency of class teachers.The scheduling system developed based on the LNMP website architecture technology proposed in this paper has optimized the scheduling work of the head teacher,and at the same time provided very effective data support for the analysis of teachers' service and the inspection of their performance.Considering the convenience and security of system development,this system uses the B/S mode,and the concept of a three-tier architecture is used for system development.The ODP framework is used for back-end development framework.PHP is used to develop the system.Relational database My SQL is used to store data,and Redis is used for caching of large computational and non-real-time data.In the requirements analysis part of the scheduling system,this article first gives an overview of the system's requirements,then analyzes the system's boundaries,clarifies the data source of the system,and finally uses the use case description table to make system user management module and the shift strategy module,shift management module and class teacher management module to explain the requirements.In the system design and implementation part,we mainly complete the followings: the system architecture,the functional module division of the system and the design of the database system.The user management module of this system implements the control of user rights and the management function of teachers' business accounts in the scheduling system.In the shift management module,the system prepares the system's scheduling work through functional modules such as lecturer binding,scheduling level setting,and strategy management before the courses online;In the shift management module,the class teacher is distributed for courses and the relevant settings are seted up for the class teacher.The user can view the enrollment of the class and the assignment.In addition,the system also has the function of assigning class teachers and replacing class teachers.Through the mutual operation and cooperation of the above modules,the requirements of the scheduling system are well realized.Finally,the function and performance of the system is tested,so as to ensure that the system can effectively support the needs of users and bring a good user experience.
