Design And Implementation Of SNS System Based On Web2.0

Web2.0is one of popular concepts in today’s Internet. Web2.0focus on user’s interaction, the user is not only the browsers of websites content, and also a maker of websites content. As the core application of Web2.0, social networks (Social Network System, SNS) is based on six degrees of separation,which is the second-generation internet after portal. With the stimulation of demonstration role of Facebook, MySpace and SNS etc., the SNS sites also grew rapidly with springing speed around the world.SNS website develops rapidly, it is much faster than traditional sites. Facing the rapidly growing users, how to solve the accessing and high concurrent requirements of a large number of users, building up mass data storage and efficient open platform, which becomes the major technical problem of SNS system.This paper analyzes SNS websites background,the situation at home and abroad and the reason of SNS websites developping rapidly,also expounds the significance of their research. For the problem of SNS system’s high access and concurrency,mass storage,stability and expansibility, we found that the corresponding solutions from below aspects:from the index optimization,database split design,image storage optimization,Cache object caching mechanism,content separation mechanism,full-text search,load balance processing,WebService open platform efficiency and other key technologies aspects.Through analyzing the key technology of SNS system implementation,the thesis has presented the design and implementation SNS system case,it has expounded above key technology solutions how to get a good application in the case’s design and implementation,also the thesis has proceeded the applied effect analysis for realizing the SNS system successfully. Through the case successful implementation and the application effect analysis,we can get these key technologies’s solution,which can improve the SNS system efficiency,also can improve the user experience effectively,bringing economic benefits for the operating platform,so as to reduce cost,improve performance,strengthen the stability and extend the effects of system’s expansibility, lay the foundation for SNS system’s further promotion,it has good prospects.
