工作学习 / 学科技术讨论 / 大家有没有想过如何设计数据库来代表人际关系,比如像LINKEDIN那样的人际网络如何在数据库中表示?我有一点想法,但是PERFORMANCE AND SCALABILITY总是一个问题?另外有没有什么研究报告或者文章可以参考,谢谢

linkedIN 应该就是一个巨大的多对多的关系表吧?

true. i guess the biggest challenge is to maintain scalability. When number of user grows, probably the cost to maintain that gigantic number of relationship is growing dramatically.

不见得. 譬如, 只用两级关系来描述每个节点(人), 每个节点用个LINK来描述与其他节点的关系. 从现在的技术, 应不成问题.
