Web 2.0 Technology And Medium-sized Web Site Building And Optimization

In recent years, the demand of people to websites is higher and higher. Especially to the large and medium-sized portal websites of industry, not only needs good interaction, mass data, but also the linking speed and the frequency of update also has direct impact to the person visit amounts. Great development of information technology today, the construction and optimization of large and medium-sized website are more and more important.Apart from the view design, images and animations making and other art works, the construction and optimization of website mainly divides into two sides, the front and the background. The front refers to the display on the browser, including the way of layout, the page script, such as effects, the background refers to the programs of server-side and database-related.Based on web2.0 idea, the construction and optimization of website can be as follows: using the Div + Css way of layout to the front; using the static file cache for the data display of background; using Ajax technology to achieves "download-on-demand" and "asynchronous interactive" of the content. In addition, web data mining method can also be used to adjust the structure of the site regularly or irregularly, to release information of strong timeliness and high visit rate to the visitors for access costs as little as possible, expect to achieve the visit efficiency of pages of websites to maximize and best. With more and more Web2.0 technology used in many large-sized websites at home and abroad, in the field of the construction and optimization of website, Web2.0 has become an irresistible trend.The works accomplished in the subject as follows: structured Apache web server, Ftp server and MySql database server on Linux. Reconstructed the layout of pages of table way to Div + Css way, achieved static file cache sub-moduled in Php + MySql configuration, achieved download-on-demand and asynchronous interactive in website construction by using Ajax technology.Achieved the targets of the following: reconstructed the layout of the homepage of China Welding Information Website to Div + Css way and achieved static file cache sub-moduled of it, built the layout of the China Welding Home in Div + Css way, built the layout of Welding Equipment Business Information Website in Div + Css way and achieved static file cache sub-moduled of it. Through series of development examples, analyzed the effect of web2.0 on the construction and optimization of large and medium-sized website quantitatively.Using web data mining method, explored the theoretical basis of adjusting the structure of website, put forward a theoretical basis and the specific algorithm of adjusting the structure of China Welding Information Website, and tested it in part of typical modules as an example.
