家园 这个这个,我又得去查一下

好像还真的是SQL Server,这个是05年的消息:外链出处

As the organization prepared to retire its aging large mainframe computers, it deployed Microsoft SQL Server 2005 on two 4-node clusters to support its Market Data Dissemination System (MDDS). Every trade that is processed in the NASDAQ marketplace goes through the MDDS system, with SQL Server 2005 handling some 5,000 transactions per second at market open. SQL Server 2005 simultaneously handles about 100,000 queries a day, using SQL Server 2005 Snapshot Isolation to support real-time queries against the data without slowing the database. NASDAQ is enjoying a lower total cost of ownership compared to the large mainframe computer system that the SQL Server 2005 deployment has replaced.

简单来说就是大机(Mainframe)被替换了。

还有一个新闻就比较负面了:外链出处

个人认为有两点应该留意:

1. 侧面证实应该用了SQL Server,毕竟在Windows Server 2003上面,不会用其他数据库了吧?

2. 这个已经是10年老的操作系统了,Nasdaq不更新,也赖不到微软的头上去。
