微博系统设计

1. 新浪微博数据库是如何设计的

这个问抄题的答案好像很复杂。可以看下新浪微博架构师TimYang的《构建高性能的微博系统——再谈新浪微博架构》
谈谈个人看法：
微博技术架构的关键点在于如何优化Cache和消息队列的使用效率，以及合理规划数据存储方式。
如此海量的数据推送必然是通过异步消息队列处理，而不是简单的数据库直接写入，因此系统的负载压力会逐层分散到后端数据库上，并不是集中于某几台数据库上。
新数据通知，应该通过各种基础服务预先计算出的数据集合，再通过客户端每30秒的轮询请求返回，并非请求后的实时计算，因此压力可能更多的集中在cache层上。

4. SNS,微博 好友关注和推送功能的数据库设计是怎么实现的底层设计

用户离线了是没法通知的，因此没必要通知所有关注的人。一个大v可能被很多人关注，但是关注的人就不会很多，1000很多了吧，1万应该是机器人了吧。因此每个用户在线的时候去读取有没有推送信息更简单。

5. 高分悬赏，有没有asp.net和C#都懂的大神，我做了一个基于ASP.net校园微博系统的设计与实现，求帮助

你把代码发上来。
少量修改还可以。
大量的话，网络知道一般没人给弄的。

6. 如何设计一个PHP微博系统的框架

可以用的,只是你需要查出"反馈最活跃的10个用户的最后一条微博" 的数据,数据库的select语句可以实现你的需求的,与用什么数据库无关

7. 什么是微博管理系统

微博管理系统，从字面意思就知道是管理微博的，如果老师没有特定的要求，你就可以自行发挥啦。细想一下，就是管理注册用户、用户资料、用户动态、广播通知等等……

9. 跪求高手用java做一个简易微博系统设计

你这样是求不到的，高手都很少写大篇的程序。主要是没分，当然 我不会写！
建议：你问的时候问解决问题的方法，而不是要程序！
