Design And Implementation Of Enterprise Online Education System Based On Three-tier Architecture

As the establishment of learning organization is becoming more and more important,enterprises have strengthened the strength of quality education and training for employees.How to properly deal with the contradiction between strengthening education and training and controlling the cost of training will be an important issue that restricts the development of education and training.With the development of the information level,the online education system emerges as the times require.It provides a possibility to solve the above contradiction.After investigating the demand of online education,a clear role requirement,functional requirement and performance need are formed.Based on that,the platform is designed in detail.The system architecture box is defined through the performance requirements,which corresponds to the functional responsibilities of the hierarchy.The main modules of the platform are four modules: online resource management,course management,training management and examination questions management.The main basis of partitioning is the functional requirements of the system.According to the requirements of system design in software engineering,output platform development needs process design and database design,and meets the pre requirement design requirements from the overall function and performance design,supporting subsequent implementation and testing work.In the process of project design and system development,it mainly follows the tenet of "overall design,distribution implementation,resource sharing and rational allocation".The system combines current advanced technology and database technology to maximize the utilization of resources and optimize the structure of talent quality and enhance the level of education management.The system chooses Visual Studio 2008 as the system development platform,and the SQL Server 2005 enterprise version is developed as a database.The development environment is Windows Server 2003,and the configured.NET environment ensures the reliability of the system development efficiency,operation efficiency and maturity.Through the experience accumulated by enterprises,we can achieve the functions and modules in the online education system,and provide platform support for the training and learning of employees after they are put into operation.According to the related theory of system testing,the function and performance of the system areverified to ensure that the operating requirements of the system conform to the actual requirements of the enterprise.The running platform can support all kinds of personalized learning needs,and has excellent marketing potential.
