The Design And Realization Of Tag System Which Based On Web 2.0

The tag system, based on web 2.0, aimed at the use of tags and their sort. Its purpose is that people could make the tags when they were reading articles, looking over links and writing logs. And people would find the content they wanted expediently by their tags. The system has the functions including entry and management of users, management of tag's sort, management of tags, collection and management of articles, collection and management of links.This article firstly summarize the technology and kernel application of web 2.0, and then explain detailedly the tag system's processes of analysis, design and development by applying data flow chart, E-R chart and data dictionary. The full text is totally divided into introduction, summary of Web 2.0,design of tag system based on Web 2.0,realization of tag system based on Web 2.0,test of tag system based on Web 2.0,summarization and prospect six parts. The system adopts B/S(Browser/Server) develop mode, and the developing tool choice cross-platform, open type, safe function better ASP.NET 2.0 language, the backstage database chooses to use Microsoft SQL Server 2005.Three layers of system structure of system adoption is Dataâ†'Data Access Layerâ†'Performance Layer of Web Page, that is the head's performance logic realized by ASP.NET 2.0 web page, the center uses Visual Studio 2005 module to carry out the system internal complicated business logic, and the behind uses SQL Server 2005 database to carry out data logic.The text brings forward resolvent of the tag system based on Web 2.0.The resolvent realizes several usual functions such as addition and management of tags and their sort, collection and management of articles and links, search tags, move tags, tags sequence and so on. The system's interface is terseness and handsome, easily use. And the system expends small computer resource, has quick link speed, so I hope the tag system could supply convenience for the users who like using tags.
