SSH交友系统是一个集休闲性、即时性、蕴含用户隐私信息的一个网络系统。

The SSH dating system is a network system that integrates leisure, immediacy, and contains user privacy information. Therefore, its development must achieve reliability, ease of use, maintainability, and scalability. <br>(1) Reliability The reliability of the <br>system includes several aspects such as maturity, fault tolerance, and easy recovery. The frequency of system failures should be controlled within an acceptable range to ensure that the system is mature and complete in the basic sense. When a fault occurs, it must have the ability to handle the fault; after a serious error occurs, it must be able to restore the normal operation of the system in time to ensure the reliability of the system. <br>(2) Ease of use <br>system is a social software that is positioned for entertainment and leisure. Then the audience of the system includes professionals in the professional field and users who have little knowledge of computers. For such users, the system should be concise and easy to understand, easy to operate, and clear interface, making the system easy to use, easy to understand, easy to learn, easy to operate. <br>(3) Maintainability and scalability <br>When a system needs to run problems or needs to be changed, a well-structured system can be easily analyzed, changed, and tested. And such maintenance and changes should be stable, and will not cause collateral failures or even collapse of the system.
