主题：【原创】数据仓库软件的评测心得 -- 河蚌

现在美国有很多大银行在用teredata，和netezza.

netezza的设计思路比teredata还要激进，是 data warehouse only, 我和netezza的developer聊过，在netezza里面没有cursor,用户甚至不能创建 index.

他有自己独特的硬件优化技术。软件再怎么优化也不如专用硬件快，IMB虽然有DB2,今年还是把Netezza 收购了，这是一个DW未来的方向

oracle 推出 Exadata 也是受了这种思路的影响

“Netezza was part of the inspiration for Exadata. Teradata was part of the inspiration for Exadata,”

“We’d like to thank them for forcing our hand and forcing us to go into the hardware business.”
