Design And Implementation Of Micro-course Management System For Mobile Platform

Micro course system is an effective complement to traditional learning,it provides a highly efficient,convenient and flexible teaching mode,the paper design and development of curriculum management system,using the mobile platform,and the convenience of online learning,more in line with the micro study characteristics,the introduction of online learning mode,completed the study effect test,system application can realize the integration of teachers,students micro teaching management model,improve the level of online learning ability in an all-round way.Thesiss from the current micro course demand as the goal,through the unified modeling language(UML)to analyze the micro study of related business processes,on the basis of the analysis process,through the use case diagram describes the curriculum resources in micro management,online classes,online c ommunication and backstage management function model of the big four,and nonfunctional requirements of the system are analyzed.Thesis is based on JavaEE framework to complete the system architecture and the system module structure design,proposed the user interface layer,business logic layer and database layer of multilayer framework,through UML sequence diagrams,class diagrams,and completed the curriculum resources in micro management,online classes,online communication and backstage management function module of detailed design,through Visio tools to design of system database model,the core physical data model design was presented.On the basis of design,the technology of micro-course resource management,online course,online communication and background management is realized through Java language and the development platform of JavaEE.In addition to completing the online learning of micro courses,the system also introduces the functions of online communication and micro course statistics,changes the previous mode of limited micro-course learning and resource management,and enhances the interaction between teachers and students.Thesiss completed system function test and performance test,through the function test shows that system meet the expected design goal,through testing the system performance in LoadRunner platform,indicate that under the condition of 5000 users concurrent access to the system running stability,performance meet the design requirements.
