Analysis And Design Of Shandong Tax Education Network Platform

The improvement of the tax system reform has led more and more complicated burden for vocational education of Shandong tax system. An e-learning platform based existing network has been become almost a unique choice. Under the basic principals of e-learning, this dissertation expounds key technique issues of network education platform, such as demand analysis, design of framework, detailed design and so on.Based on the practical development of software system, this dissertation expound the ideas, methods and procedures applied to the system , including demand analysis, frame design, detailed design and so on. And the key issues encountered during development and correspondent approaches are also referred.First of all, a thorough and in-depth analysis is necessary. With the object-oriented language UML, business-training flowcharts, e-learning and test flowcharts are put forward. And the administration of network education platform, network instruction and network examination, three functional demands are also presented with case graph.Secondly, main framework of the Shandong revenue education system is designed. Under the demanded objectives and the principles of design, the following frameworks is designed: system architecture, application architecture, deployment framework and system security architecture. From the point of view of architecture, the system is divided from top to bottom into the application layer, and operation layer and data layers. Operation layer and data layers have a more detailed breakdown.Then detailed design of the system is presented. The technique implements on data access control based on the role are researched and developed. Users' accesses to data are controlled by the following measures: Define roles for different users respectively; Assign corresponding permissions for different roles; Limit accesses to data to those roles having relevant permissions. The process of access control is comprised of two parts: one is the relating between the permission and the role; the other is the relating between the role and the user. We also finished designing the object oriented database and correlative optimization work And the help of Jsp, Servlet, and other technology to achieve. In order to ensure that system will be adaptive to the future demand, we make the system structure flexible while the efficiency is assured.The system has been running for some time and a good effect is revealed, which will promote the informationization construction of Shandong revenue.
