  • 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
    • Good question, hope this article helps.
      • thanks, reading ...
    • 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.
