20121108 Oracle Developer Day

今天应邀参加了Oracle Developer Day。 很长时间没有参加Oracle的Developer Day活动了,上次可能是4年以前的事情了。那次参加还是去学习的,这是变成了特约技术专家了。 这次巧合的是,Oracle把Developer Day的会场也放在了国宾宾馆,且就在我们的Oracle技术嘉年华前一天,于是下午去附会的同时可以去热热场子。 今天的会议都是大数据相关的主题,而我的工作和经验基本上和大数据没有太多关系,本来去参加会议也就是打打酱油,不过没有想到现场朋友的提问基本上都是Oracle DB相关的问题,基本上和大数据没有什么关系。不过也好,要真是大数据相关的问题,我也没有办法解答。 最后,今天Developer Day最后的专家交流活动变成了恩墨的专场,现场的4个专家分别是Kamus、圣文、老熊和我。

OLAP用户手册

这篇文档介绍了OLAP相关的基础概念。 Oracle的OLAP组件从9i就独立存在了,不过一直没有研究过。由于有客户在使用,且前一段时间发现OLAP组件的SCHEMA并不像其他数据库SCHEMA迁移那么简单,因此还是有必要了解一下相关的知识。 在线文档地址:http://www.oracle.com/pls/db112/to_toc?pathname=olap.112%2Fe17123%2Ftoc.htm&remark=portal+%28Books%29
