事务处理与分析处理
OLTP vs OLAP
动机:早期的数据库通常对应于商业交易领域,例如销售、订单、支付员工工资等。后来当数据库扩展到了不涉及金钱的领域,事务一词仍然存在,主要指 组成一个逻辑单元的一组读写操作。即使数据库被用于例如博客的评论、游戏中的动作、通讯录中的联系人等,其基本的访问模式仍然与处理业务交易类似。应用程序通常使用索引中的某些键查找 少量记录,因为这些应用程序是交互式的,所以访问模式被称为 在线事务处理(online transaction processing)。
不过随着商业进步,数据出现了一些不同访问模式,下面有几个是不同的.
某在线游戏中指定游戏角色的等级是多少
购物网站中一个订单记录
博客里的某篇文章获得了多少点赞

关于DRG
疾病诊断相关分组(Diagnosis-Related Groups,DRG)诞生于上世纪60 年代末的美国。上世纪80 年代,美国率先将DRG 用于医疗保险定额支付,现今多数发达国家社会医疗保险都采用这一工具进行预算、资源配置管理或购买医疗服务。从本质上讲,DRG 既能用于支付管理,也能用于预算管理,同时还是促进医疗服务质量提升的有效工具。

TDengine是一个新兴的时序型数据库,可以参见GitHub项目。学习一个开源项目,最直接的方式就是先成为一个用户,先把项目运行一下试试看。
数据库现在的行业趋势好的让人羡慕,涛思数据完成4,700万美元B轮融资 经纬中国领投。要是去年毕业还想投个简历呢(可惜不小心读了个研究生)。受此影响,现在开始看DDIA这本书了,不知道研究生毕业是不是来得及
简单粗暴tensorflow是我个人很喜欢的一个教程。很多代码,可以暂时先不详细了解原理,先 run 一下或许有的问题就不存在了。本文面向:

北邮人发匿名忙。互联网,哪家强。前端后端,还是算法香。阿里腾讯宇宙厂,都不难,有手上。
兄弟学校不要狂。九八五,又何妨?感觉就业。。。不如北邮强。若问导师好不好,都不行,赶紧run。
《沁园春·北邮》
北邮风光,西土城边,论坛治校。
看称职导员,未开刃刀;外卖佳肴,无人来盗。
招生尽力,休要争吵,分数多高就多高;
待九月,看渣硕菜鸟,百万总包。
北邮如此多娇,引无数学子竟折腰。
惜中科理航,难以挣刀;
电子科大,西南一角;
道口体校,分数最高,就业还是一样招;
皆渣矣,问哪里最好,还是本校~
闲暇做调侃,以后不会再写了,没啥新意了

今天应本科的导员邀请给果园大四的同学分享了一下考研经验。老实讲我自己真的很菜,本科只坐在下面听大佬讲的那种水平。现在居然能轮到我分享经验了。PPT我放在后面了,好不好总之就那样啦。
分享结束后有同学问了一些问题,用文字来统一回答一下吧(正好水一篇论坛)~
Q1: PPT中提到了数一真的很难,我做难题的时候也这么觉得,那么我还要做吗?
我的建议是,还是做一做,不要随便跳题。数一出现陌生题目很正常,还是要勇敢去做的。
我说的做数一崩溃了、破防了、做哭了都是正常存在的,因为这门课就是有些难度的。但这并不是让你不做,而是做破防了崩溃了做哭了也要习惯并接着做。
举例还是,我说一段代码可能会报错,而且无法预知。并不是说这段代码就不运行了,而是你要去try catch..</p><a class="button is-default mt-2 has-text-weight-semibold" href="/2021/11/26/%E7%BB%99%E6%9E%9C%E5%9B%AD%E7%94%B5%E7%AE%A1%E5%90%8C%E5%AD%A6%E7%9A%84%E8%80%83%E7%A0%94%E7%BB%8F%E9%AA%8C%E5%88%86%E4%BA%AB%E4%BB%A5%E5%8F%8A%E4%B8%80%E4%BA%9B%E7%AD%94%E7%96%91/">更多</a></section></article><article class="post-item-card"><header class="is-relative is-flex"><div class="post-cover-backdrop is-hidden"><img src="https://i.loli.net/2021/11/21/bGcUdyK4NCPJ9Mp.jpg" alt="loading.."></div><a class="post-cover-link has-text-centered skeleton" href="/2021/11/21/%E3%80%8A%E9%9D%9E%E7%BA%BF%E6%80%A7%E5%85%89%E7%BA%A4%E5%85%89%E5%AD%A6%E3%80%8B%E7%AC%AC%E5%9B%9B%E7%AB%A0%E7%AC%AC4%E9%A2%98%EF%BC%8C%E6%88%91%E7%9A%84%E8%A7%A3%E7%AD%94/"><img class="post-cover-img js-img-fadeIn" src="https://i.loli.net/2021/11/21/bGcUdyK4NCPJ9Mp.jpg" alt="loading.." data-backdrop="true"></a></header><section class="content post-card-content p-4 pb-5"><header><a href="/tags/%E9%9D%9E%E7%BA%BF%E6%80%A7%E5%85%89%E5%AD%A6"><i class="tag post-item-tag">非线性光学</i></a></header><h2 class="mt-4 mb-0 is-family-serif"><a href="/2021/11/21/%E3%80%8A%E9%9D%9E%E7%BA%BF%E6%80%A7%E5%85%89%E7%BA%A4%E5%85%89%E5%AD%A6%E3%80%8B%E7%AC%AC%E5%9B%9B%E7%AB%A0%E7%AC%AC4%E9%A2%98%EF%BC%8C%E6%88%91%E7%9A%84%E8%A7%A3%E7%AD%94/">《非线性光纤光学》第四章第4题,我的解答</a></h2><time class="has-text-grey" datetime="2021-11-21T00:33:04.000Z">2021-11-21</time><p class="is-flex-grow-2 mt-2">《非线性光纤光学》第四章第4题,我的解答

1. 新建GitHub仓库,本地项目
GitHub上新建一个名为 .github.io 的仓库,这样命名的仓库是一个特殊的仓库,详见github.io
本地用npm安装hexo
npm install -g hexo
初始化项目,简单来说就是运行这个命令:
hexo init
本地看看
hexo s
然后本地浏览器访问 localhost:4000

这学期开始就是研究生了,说实话算上从疫情开始就没有怎么好好上过线下课了(大四上在忙考研,大四下毕设没啥课了),还真的有些不适应哈哈哈。
这学期比较有挑战的课感觉就是实验室导师张晓光老师讲的非线性光学了,用的书是北邮新出的《非线性光学》。

第一次出版,第一次印刷,还是主编亲自讲,当然必须要找编者签个名啦·

其实这个是讲座最后的部分了,不过北邮人都是务实的,我也不说虚的了。开门见山先讲这个。作为一个每天在悄悄话冲浪的闲人,很多学生常常抱怨“导师思想保守不肯放实习”“实习单位学不到技术就是拧螺丝”“实习项目没啥技术高手真想跑路”。其实呢,参..</p><a class="button is-default mt-2 has-text-weight-semibold" href="/2021/10/11/%E6%8B%A5%E6%8A%B1%E5%BC%80%E6%BA%90%EF%BC%8C%E5%90%AC%E6%8A%80%E6%9C%AF-%E5%BC%80%E6%BA%90%E8%AE%B2%E5%BA%A7%E7%9A%84%E4%B8%80%E7%82%B9%E6%84%9F%E6%83%B3/">更多</a></section></article><section class="paginator is-flex is-justify-content-flex-end is-flex-wrap-wrap mt-5"><span class="page-number current">1</span><a class="page-number" href="/page/2/">2</a><a class="extend next" rel="next" href="/page/2/"><i class="iconfont icon-next has-text-grey"></i></a></section></section><aside class="column is-hidden-mobile is-4-tablet is-3-widescreen"><style>.search-widget .search-input {
