发帖数: 581 | 1 请问：我直接建materialized view和建在prebuilt table上各有什么advantages and
disadvantages？
在什么情况下，用哪个方法建MV？
另外，我refresh prebuilt table MV 会不会把prebuilt data但不合MV的select statement给清掉了？ |

发帖数: 236 | 4 Estimated Life Expectancy Chart
The following chart details the predicted life expectancy of household
materials and components.
Interior and exterior paints can last for 15 years or longer, however
homeowners often paint more frequently. Surface preparation is likely the
most important determiner of paint life expectancy.
ADHESIVES, CAULK AND PAINTS YEAR
Caulking 5-10
Paint 7
Roofing Adhesives 15+
Appliance life expectancy depends to a great extent on the use it receives.

发帖数: 21731 | 5 Facebook will bleed the majority of its users over the next three years,
according to a pair of Princeton researchers in a new paper (PDF).
Those researchers, John Cannarella and Joshua Spechler, arrived at that
conclusion by comparing Facebook to an infectious disease. That’s sort of
logical: both depend on networks of human beings to “transmit” and grow;
and just as people shake off viruses, they should (according to the theory,
at least) eventually stop using Facebook: “Recovery spreads infec... 阅读全帖 |

发帖数: 1759 | 6 4马蹄我主要关心glk/c他们的45/55的。我看到他们是spring preloaded. 大概类似于
haldex的Prebuilt pressure吧
单就前后轴torque appropriation来讲，也就是说haldex和xdrive反应略逊于Quattro
效果优于4matic?
50nm怎解？前后轴slip大于50就engage? 这个数字和quattro比如和？ |

发帖数: 19468 | 7 GLK/C就是我前面说的行星齿轮差速器配机械离合器限滑，那个preload是说离合器的，
比如，如果离合器有50Nm的preload，具体的含义你可以去俱乐部爬楼，刚讨论过这个
问题。至于Haldex的prebuilt pressure，就是我之前讲的，4代开始液压由电泵提供，
所以它才能在输入、输出端没有转速差的情况下也有可能传递扭矩。这两个不是一回事
，不能望文生义……
4MATIC反应速度看你怎么说，如果你是讲离合器的部分，这是torque-sensing的，和纵
置引擎平台的quattro一样快（横置引擎平台的quattro就是用Haldex的……），只不过
这个限滑机制容量有限而已。如果这个限滑机制不够，等ABS发挥作用，那是要慢一些

发帖数: 518 | 9 这么长的文章你都仔细读了，下面这段bleacher report 上的一定也看一下
This is pretty ludicrous, slanted reporting. Anyone can report something as
fact and make it sound convincing. Just look at the deadspin article about
Derek Jeter's "gay sexual relationship." The ESPN report fails to mention
that it is completely legal to tape from the booths, it is only illegal from
the sidelines. Filming opposing teams coaches for signals is still legal
today. When Mike Shanahan was coaching the Broncos he said himself "Our guys

发帖数: 1106 | 12 Many BI tools would present a logical multi-dimensional view, but in terms
of products with a physical MOLAP engine. MS Analysis Service and Oracle
Hyperion Essbase are the two most prominent
ones. Essbase is a much more pure MOLAP. Both support the rather popular
query language MDX.
SAP BW is another one but it is pretty much tailored for its apps. Oracle
has another in database product call Oracle OLAP option, but it is suffering
from an obscure language.
Physical MOLAP can be a good solution... 阅读全帖 |
