The Design And Implementation Of Online Learning System Based On Android

Today's era is an era of rapid development and efficient integration of information technology.Since the "Internet plus" economic model was put forward in 2015,it can be said that the hot wind is blowing.All walks of life are trying to integrate the Internet,big data and cloud computing into traditional industries,driven by network technology and the rapid growth of basic education.With the birth of demand,the "Internet + education" has sprang up,and the traditional classroom education has been on the way of education reform.Schools,training institutions,enterprises and institutions have also integrated their own advantages in technology resources,and have launched the mobile learning APP.This paper investigates the current situation of staff training and self-learning in small and medium-sized enterprises,and finds that the situation of on-site teaching in conference rooms is still prevalent in enterprises.Because of the fierce market competition,employees need to supplement their professional knowledge at any time to improve their ability.At the same time,enterprises should assess the professional skills of employees so as to facilitate targeted organizational training and synchronize the latest development trends and professional technology in the industry.Based on this,this paper studies and implements an Android-based online mobile learning system for small and medium-sized enterprises,which is implemented by both front-end and back-end systems.It provides online learning,online testing,news dynamics,forum communication and personal settings.This paper carries out feasibility analysis,functional requirements analysis and business process analysis of online learning system based on Android.The original requirement of the system is described comprehensively by flow chart and use case diagram with object-oriented idea and UML tools.After defining the requirement scope and refining the requirement,the key links to realize the online learning system are defined.In this process,the basic principles of ensuring scalability and reducing the coupling between functions of the system design are formulated.The technology of online learning system is to use JAVA language and Android SDK to realize the client and MySQL to store data,so as to complete the overall design.In the detailed design part,according to the results of functional module design,the database model is analyzed,and the E-R diagram and database table structure are output.Finally,the key functions of the online learning system based on Android are demonstrated.After completing the encoding of all functions,test cases are designed to test the whole process,so as to cover every branch scenario and ensure the robustness of the system.The online learning system realized in this paper breaks the time and space restrictions,achieves resource sharing,interacts quickly and solves problems,mobilizes the enthusiasm of employees to study independently,improves work efficiency,reduces training costs,enables managers to control staff's professional skills,strengths and weaknesses in a timely manner,assists leaders in decision-making and improves enterprises.Soft power and market competitiveness.
