Research And Development On The Portal Of Software Site

With continuous development of Computer Technology, Portal becomes one of the chief ways in getting and conveying information. The author initially studied portal architecture and implementation technology. According to the actual needs of a city software site, the system is analyzed and designed with UML. Then the software site portal is developed by Visual Stdio.Net 2005 environment with Role-based Access Control theory, AJAX, Web Services, RSS and other key technologies. Now it has been put into practical operation.The portal system is designed by modular structure, which facilitates the management of the system administrator and the expansion of system. The Multi-Granularity of Access Control Strategies can effectively prevent unauthorized access to the system. When accessing to the web site, the user can use the online RSS reader to access all the information with the function of information push and aggregation based on RSS. At last, the system is optimized by the Web server optimization and database access performance optimization to improve the overall performance of the web site.This paper detailed described the work of the software site portal, which includes the system analysis, design, implementation and maintenance. Basic theory, method and technology used in the development of the system are also introduced in this paper.
