It is said that English speakers fall into three groups: those who have learnt it as a mother tongue, those who have learnt it as a second language through exposure(显露) in a society where it is spoken, and those who are forced to use it for administrative(管理的), professional or educational purposes.
This third group, along with the supremacy(至高地位) of English in the business world, has created a fast development in institutions offering English for business. However, the average business person, while happily accepting the challenge, does not have any idea how long the process may take.
Duncan Ford, a specialist in language teaching theory, partly puts the blame on misleading publicity and says that you have to think in terms of hundreds of hours while people still think learning a language is a three-hour-a-week job.
According to him, the key is lots of variety of the activities similar to the happiness of the class. The communicative way has replaced the old–fashioned note-taking method and for those people who think that a couple of hours with the latest CD-ROM is not to replace for English classes, they should think again. While seen as a useful back-up, they are not teacher replacement.

问答题 案例分析题

阅读下列说明,回答问题1至问题3,将解答填入答题纸的对应栏内。

说明:某集团公司在全国不同城市拥有多个大型超市,为了有效管理各个超市的业务工作,需要构建一个超市信息管理系统。

需求分析结果:

(1)超市信息包括:超市名称、地址、经理和电话,其中超市名称唯一确定超市关系的每一个元组。每个超市只有一名经理。

(2)超市设有计划部、财务部、销售部等多个部门,每个部门只有一名部门经理,有多名员工,每个员工只属于一个部门。部门信息包括:超市名称、部门名称、部门经理和联系电话。超市名称、部门名称唯一确定部门关系的每一个元组。

(3)员工信息包括:员工号、姓名、超市名称、部门名称、职位、联系方式和工资。其中,职位信息包括:经理、部门经理、业务员等。员工号唯一确定员工关系的每一个元组。

(4)商品信息包括:商品号、商品名称、型号、单价和数量。商品号唯一确定商品关系的每一个元组。一名业务员可以负责超市内多种商品的配给,一种商品可以由多名业务员配给。

概念模型设计:根据需求分析阶段收集的信息,设计的实体联系图和关系模式(不完整)如下:

关系模式设计:超市(超市名称,经理,地址,电话)部门((a),部门经理,联系电话)员工((b),姓名,联系方式,职位,工资)商品(商品号,商品名称,型号,单价,数量)配给((c),配给时间,配给数量,业务员)

问题1:根据问题描述,补充四个联系,完善图2-1的实体联系图。联系名可用联系1、联系2、联系3和联系4代替,联系的类型分为1:1、1:n和m:n(或1:1、1:*和*:*)。 问题2:(1)根据实体联系图,将关系模式中的空(a)~(c)补充完整;(2)给出部门和配给关系模式的主键和外键。 问题3:(1)超市关系的地址可以进一步分为邮编、省、市、街道,那么该属性是属于简单属性还是复合属性?请用100字以内文字说明。(2)假设超市需要增设一个经理的职位,那么超市与经理之间的联系类型应修改为(d),超市关系应修改为(e)。
