将 TeraData 用于不太大的应用程序
几个月前,我看到了 TeraData Express Edition。我对这个野兽一无所知。我想知道它是否仍然带有 Express Edition,以及将此数据库用于基于 Windows 的中型应用程序是否是一个好主意。
Few months back I saw TeraData Express Edition. I have no idea of this beast. I want to know whether it still comes with Express Edition and whether it is a good idea to use this database for Windows based mid-sized apps.

这实际上取决于您想用这个应用程序做什么。从应用程序的角度来看,Teradata的一个很大的弱点是它不支持读已提交事务隔离。如果您尝试使用 Teradata 作为 OLTP 数据库,那么您可能想尝试其他方法。如果你用它来处理数字,那么是的,就用它吧。问题之一是 Teradata Express Edition 的支持不那么好。 Express 版本本质上是某个版本的数据库快照。如果您发现并报告错误,您将需要很长时间才能收到修复。 Teradata 每个数据库版本仅发布一次 Express 版本。但是(imo),如果您购买真实版本,您将收到一个非常快速的补丁,该补丁将被滚动到数据库软件中。
It really depends on what you want to do with this application. From an application perspective, a great weakness of Teradata is that it does not support read committed transaction isolation. If you are attempting to use Teradata as an OLTP database, then you might want to try something else. If you are using it to crunch numbers, then yes, go with it. The one issue is that Teradata Express Edition is not supported that well. Express edition is essentially a snapshot of the database for a certain release. If you find and report a bug, it will take a long time for you to receive a fix. Teradata only releases the express editions once per db release. However (imo), if you buy the real version, you will receive a pretty quick patch which will be rolled into the database software.
我在技术支持工作中使用 Teradata。我从事数据库中间件工作,Teradata 是我们支持的数据存储之一。中型的定义?每秒 1-200 笔交易?我可以对抗任何常用的数据库。 10000 点/秒?也许不是——也许你会选择企业版。
I use teradata in my technical support work. I work on database middleware, and Teradata is one of our supported data stores. Define mid-sized? 1-200 transactions per second? I'd stand ANY commonly used database up against that. 10000 tps? Maybe not - maybe you go to the enterprise edition.
