来自主题: Database版 - 求救,咋样架起来自己的database?
诸位,本人非相关背景,水平很弱,希望大家能够指教。
我最近需要干的一件事情是建一个database使得我在一个局域网的几台机器上(有
windows, 有linux)上面都能用。我不在乎是哪种database,最好简单些就行。
自己前两天下载了一个Oracle 10g Express. 在Windows机器上设置好了。本地可以访
问。insert, select在不同的软件里面用了都不成问题。但我就是搞不定如何在别的机
器上访问它。
这个database存在的意义就是共享一个机器上上传的数据。其它机器上能不装多余的软
件就尽量不装。
谢谢!

用php很方便,把select statement,还有create statement,insert values statement,
任何sql语句放在php里面执行,都可以.而且php直接生成网页,显示你搜索database得到
的结果,非常方便.用户看不到你的php源码和database的源文件.
听说有公司的database文件就是一txt文件,不知道这样的公司多不多.

直接申请data modeler,architect的职位
懂data modeling 就不要作Database developer这种阿三云集的职位呢
Database developer主要是datastage,Informatica 这些tool拉拉图标。sql都很少写
。database不重要,sql server不要学。

A SQL server database, has more than 10K tables. Current size is about 800G,
after data compression. ETL process happens every night. Most of them get
updated data daily, some of them get updated data weekly, and the rest get
updated data monthly. The current maintenance plan is like this:
1. Sunday - Thursday, differential backup, including data integrity check.
2. Friday, rebuild index. As of last Friday, it took 18 hours to finish
3. Saturday, full database backup, including data integrity... 阅读全帖

来自主题: Database版 - In Memory Database哪个比较好
在我的分析里,database是作为一个分析的工具,过程是这样的:一个外部的计算程序向
database里面写入大约1000行数据,然后用query读取一些aggregated数据,分析以后,然
后再写入1000行,再读,这样的读写很频繁,但是重要的是最后外部计算程序分析的结果,
写入database的数据不要求存下来.

来自主题: Database版 - object-oriented database设计咋样?
因为传统的relational database和java这样的object-oriented language的结构差别
,才会出现現在这么流行的orm,比如hibernate,ado.net.
那么,在刚开始建立database的时候,把它做成object-oriented database,現在流行
这么做吗?

来自主题: Database版 - object-oriented database设计咋样?
有没有人开发啥relational programming language(sql不算在内)?
看来database和object-oriented language天生就不合。既然object-oriented
database太复杂,有没有人设计一种新语言--relational language,毕竟语言是为
database服务的。
竟然发现有人做了一个新语言:

来自主题: Database版 - DBA vs Database Developer
主要想到过几年可能还要找工作。DBA可以找DBA和Database Developer。如果现在换成
Database Developer,以后再找也只能找Database Developer,换回DBA应该很困难。
这样,路是不是越来越窄?

刚刚开始学习database, 请问一下这个免费的SQL Server Express 里面可以设
Database/Server Audit Specification 来log database 的 actions吗?我找了一下
找不到。
另外第二个问题是:这个logging function是不是只能够audit 在SQL Server
Management Studio里面的数据库操作?如果我用Java JDBC从外部来连接数据库,写
query在Java程序里操纵数据库,那些java 程序引发的编辑操作(update,delete...)
会不会也被log。
谢谢,可能问题有点愚蠢,请见谅。

You cannot connect to a DB2 database without database name.
I believe DB2 JDBC does offer features to create databases.
You need to look into their JDBC documentation, if they
do publish.

There are tons of lab information managing systems (LIMS). Most of them only
work on PC. And a bad thing about them is that they were written by
programmers not biologists, so they are in general not intuitive, not
tailored to the needs of every biologist. Besides, usually you have to pay a
few hundred dollars a year. I think some may worth the money if your lab is

一个distributed database,各个host上都只保留了所有数据的一个subset。
现在要在每个host上restore所有数据。也就是对于每个host,把missing的数据从其它
host copy过来。至于选哪一个host,没有要求。
assume 所有host上数据的union就是整个database。
input是
host 1: 1 3 5
host 2: 2 3 4
host 3: 1 2 4 5 6
一种可能的output是
copy 2 from host 2 to 1
copy 4 from host 2 to 1
copy 6 from host 3 to 1
copy 1 from host 1 to 2
copy 5 from host 3 to 2
copy 6 from host 3 to 2
copy 3 from host 1 to 3
所有input要从stdin输入。
跟上一题同样的,最难的不在算法,而是短时间内写出code编译运行出正确结果。这题
可能还需要点数据结构。
