问题描述
我发现数据库通常有两种风格,传统的面向行的RDBMS或面向对象的数据库(OODBMS)。然而,在90年代中期,我记得,一个新的数据库类型显示为列导向。其中一些被赋予4GL这个术语,但我不认为这是一个被困住的术语。
我想知道的是以下内容:
我记得使用的两个面向列的数据库是FAME和KDB。 / p>
解决方案
是一个开源的面向列的数据库系统,基于建模。 p>
I've found databases typically come in two flavors, your traditional row-oriented RDBMS or an object oriented database (OODBMS). However, in the mid 90s I remember, a new breed of databases showing up that were column oriented. Some of these were given the term 4GL, but I don't think it was a term that stuck.
What I'd like to know is the following:
- What column oriented databases still exist?
- What are the performance characteristics of these databases?
- Are there any open source column oriented databases?
- What platforms do they interoperate with (.NET, Java, etc)
- What's been your general experience with them?
The two column oriented databases that I remember working with are FAME and KDB.
解决方案
HBase is an open-source column-oriented database system modelled on Google's BigTable.
