某商品销售管理系统使用SOL Server 2000数据库。在数据库中有销售单据表,其建表语句为:

CREATE TABLE销售单据表(销售单据编号 varchar(8) primary key,付款总金额 money,销售日期 datetime,销售人员编号 varchar(8),收银台编号 varchar(8))

由于该表数据量巨大,因此建立有销售单据历史表,将6个月以前的数据从销售单据表转入销售单据历史表,销售单据历史表的结构与销售单据表相同。

设已在销售日期和销售人员编号列上建立了索引。

①现需查询编号为“001000”的销售人员的全部销售情况,有如下两个SQL语句:

Ⅰ.SELECT销售单据编号,付款总金额,销售日期 FROM销售单据表WHERE销售人员编号=’001000’UNION

SELECT销售单据编号,付款总金额,销售日期 FROM 销售单据历史表WHERE销售人员编号=’001000’

Ⅱ.SELECT销售单据编号,付款总金额,销售日期 FROM 销售单据表WHERE销售人员编号=’001000’UNION ALLSELECT销售单据编号,付款总金额,销售日期 FROM 销售单据历史表WHERE销售人员编号=’001000’请比较以上两个SQL语句的执行效率,并说明原因。

②设此数据库的数据存储在由两块146G SAS硬盘组成的软件RAID1上。随着业务发展,数据库数据量逼近100G,且磁盘I/O很重。现考虑对硬件进行升级,有三种不同配置方案:

Ⅰ.采用两个3.46GHz六核Intel xeon 5600系列处理器,16G内存,4块300GB SAS硬盘,使用硬件RAID卡做RAID 1+0

Ⅱ.采用两个3.46GHz六核Intel Xeon 5600系列处理器,16G内存,4块300GB SAS硬盘,使用硬件RAID卡做RAID 0

Ⅲ.采用两个3.46GHz六核Intel Xeon 5600系列处理器,16G内存,4块300GB SAS硬盘,使用软件RAID 5请分别从系统可用磁盘空间、磁盘I/O性能和系统可靠性上对以上三种方案进行比较。

     Remember how great exercise was when you were a little kid?Back then, racing around the

playground or skipping rope for hours, you weren't thinking fitness, you were thinking entertainment.

But in this age of high-tech home equipment and underused gym memberships, the simple joy of

jumping rope has been forgotten.Rediscovering it will give you a total-body exercise you can find.

     Although considered an excellent  form of exercise, jumping rope  has  never gained widespread

acceptance because of two fundamental reasons.First, most people recognize jumping rope as an

excellent form of cardiovascular (心血管的) exercise, but they also believe that it is simply too

difficult.In other words, they don't think they'll be able to continue jumping for the near 20 minutes

that it takes to achieve a beneficial physical outcome.Second, many view it as somewhat boring and

overly repetitive-not as something fun or enjoyable.

     As a matter of fact, jumping rope can be great fun if you find a proper way to practice it.Instead

of doing the usual two-foot bounce over and over again, people good at rope-jumping often change

their pattern every 10 or 20 jumps.A single bounce, a double-bounce, a skip, a knee-up, side swings

as well as a variety of other easy-to-learn free-style rope-jumping.

     Now researchers are learning that jumping rope also prepares the brain for learning.It is an exercise

allowing both brain hemispheres to perform in parallel to each other.In short, jumping rope can be a

life-long activity requiring little equipment, time and space, yet leading to a much healthier life.
