Money! I   40 deep into thought. Is it money that comes between us? Money itself has no   41 ; yet it cannot simply be   42 to be good or bad. The problem  43  what attitude we have towards it.
At present, we have a more   44  material life than before, but we’re becoming more and more 45 . Why? In my opinion, the   46  is the change in people’s personal   47 . They wrongly believe that   48 money should be their only aim in life, so they   49  all sorts of ways they can to  50 this aim.

问答题

阅读下列说明,回答问题1至问题5。

【说明】

某仓储超市采用POS(Point of Sale)收银机负责前台的销售收款,为及时掌握销售信息,并依此指导进货,拟建立商品进、销、存数据库管理系统。该系统的需求分析已经基本完成,下面将进入概念模型的设计。

【需求分析结果】

1.销售业务由POS收银机来辅助实现。POS机外接条码阅读器,结账时收银员将商品的条码通过阅读输入器输入POS机中。所售商品数量默认值为1,可以由收银员修改。POS机根据输入的商品信息,打印出图22-1所示的购物清单。

2.将经销的商品分为直销商品和库存商品两大类。直销商品的保质期较短,如食品类,由供应商直接送达超市,管理员将过期的商品返还给供应商处理;库存商品由采购员向供应商提交订购单,供应商根据订购单送货。超市会不定期对库存商品按照折扣率进行打优惠。

直销商品和库存商品的送货单样表分别如图22-2、图22-3所示,其中直销商品生产批号的前六位表示生产日期。

3.超市的硬件拓扑结构如图22-4所示。

4.业务处理过程:由POS机存储每一笔销售记录,在每个工作日结束前汇总当日各商品的销售量至中心数据库(销售日汇总):根据当日的销售日汇总更新存货表;每笔进货记入进货表中,并及时更新存货表。

【概念模型设计】

根据需求阶段收集的信息,设计的实体联系图和关系模式(不完整)如下:

1.实体联系图(如图22-5所示)

2.关系模式

销售详单(销售流水号,商品编码,数量,金额,收银员,时间)

销售日汇总(日期,商品编码,数量)

存货表(商品编码,数量)

进货表(送货号码,商品编码,数量,日期)

商品( (b) )

【问题1】
对直销商品和库存商品进行概括,给出超类和子类,填入图22-5中(a)处所示的虚线框内,并补充联系。
