Pingpong paddles spill out of a laundry bin on the floor of Rajul Sheth's

In a quiet corner of the South Bay, just beyond the neatly trimmed, cookie-

By Daniel G. Amen, MD
My favorite physical activity is table tennis, which also happens to be the
world's best brain sport. It is highly aerobic and gets both the upper and
lower body moving in every which way — twisting, bending down low, reaching
up high, and shuffling from side to side. Plus, it gives your brain one
heckuva workout.
Also known as "ping-pong," the game is great for hand-eye coordination and
reflexes (cerebellum and parietal lobes). You have to focus (prefrontal

这三个table从一般的理解就是sales是fact table, 其他两个是dimension table.
从本身三个table的特性是这么理解,而且,
从sales table的两个column都是refe到其他两个table的也可以看出这一点。
所以不太理解为什么说三个都是dimension table.
当然实际上fact table都是有一堆fk的。
关于理解multidimensional database, 有时间的话可以看看下面的系列视频

来自主题: Database版 - 给一堆table,怎样能自动生成ERD
一个常见的问题是做一个新的复杂的数据库项目时,很多个table你不知道他们之间都
是什么关系。通过看每个table的constraints和dependecy,可以看到一个table的所有
FK都是reference哪个table的。我目前知道的在Oracle Sql Developer或Sq Server
management studio里都可以这样看到,但是只能一个table一个table的看。我想肯定
有一个tool,可以把这很多个table的关系自动生成一个ERD表,比如Table A的PK跟
Table B的FK自动连起来。请问Sql developer或sql server里都可以做吗?多谢了!

上中下三策。
上中已经被你排除了。
now, you need some serious codings and configurations to do.
idea 1) use temp table.
basically, you wanna create a view, including the report table and at least
a temp table.
when people do insert, always insert to the empty temp table first.
then you will get the row count, if the row count is small,
then insert/update it to the report table, if big, danamically create a new
temp table,
and include the 3 table into the view, so the table list in the view grows,

我们有些巨大无比的report table, 每个table有200多个columns, 所有run同样的

有的只有几千几百rows. 因为有很多的insert and update, 所以report table 没有任

1 有大的insert 和 update 非常慢。
2 用户之间影响非常大。 如果一个用户report 结果只有几百rows, but another

那不就是个TABLE UPDATE的问题么?TABLE里没有RANK COLUMN给你吧,你如果还要去
ALTER TABLE的话,那你这个SP就很外行了,原则是不让你改TABLE,你弄个TEMP TABLE
,RANK完一个放进去,TABLENAME也做成个COLUMN,然后RANK第二个再放进去,最后一次
性显示出来。如果你去ALTER TABLE的话,RUN两次在同一个TABLE加同样的COLUMN当然
会出错,这种做法也很不专业。
