【说明】
某音像制品出租商店欲开发一个音像管理信息系统,管理音像制品的租借业务。需求如下:
1.系统中的客户信息文件保存了该商店的所有客户的用户名、密码等信息。对于首次来租借的客户,系统会为其生成用户名和初始密码。
2.系统中音像制品信息文件记录了商店中所有音像制品的详细信息及其库存数量。
3.根据客户所租借的音像制品的品种,会按天收取相应的费用。音像制品的最长租借周期为1周,每位客户每次最多只能租借6件音像制品。
4.客户租借某种音像制品的具体流程如下。
(1)根据客户提供的用户名和密码,验证客户身份。
(2)若该客户是合法客户,查询音像制品信息文件,查看商店中是否还有这种音像制品。
(3)若还有该音像制品,且客户所要租借的音像制品数小于等于6个,就可以将该音像制品租借给客户。这时,系统给出相应的租借确认信息,生成一条新的租借记录并将其保存在租借记录文件中。
(4)系统计算租借费用,将费用信息保存在租借记录文件中并告知客户。
(5)客户付清租借费用之后,系统接收客户付款信息,将音像制品租借给该客户。
5.当库存中某音像制品数量不能满足客户的租借请求数量时,系统可以接受客户网上预约租借某种音像制品。系统接收到预约请求后,检查库存信息,验证用户身份,创建相应的预约记录,生成预约流水号给该客户,并将信息保存在预约记录文件中。
6.客户归还到期的音像制品,系统修改租借记录文件,并查询预约记录文件和客户信息文件,判定是否有客户预约了这些音像制品。若有,则生成预约提示信息,通知系统履行预约服务,系统查询客户信息文件和预约记录文件,通知相关客户前来租借音像制品。

Passage Three

While fashion is thought of usually in relation to clothing, it is important to realize that it covers a much wider domain. It is to be found in manners, the arts, literature, and philosophy, and may even reach into certain areas of science. In fact, it may operate in any field of group life, apart from the technological and utilitarian area and the area of the sacred.Its operation requires a class society, for in its essential character it docs not occur either in a homogeneous society like a primitive group, or in a caste society.
Fashion behaves as a movement, and on this basis it is different from custom which, by comparison, is static.This is due to the fact that fashion is based fundamentally on differentiation and emulation. In a class society, the upper classes or so-called social elite are not able to differentiate themselves by fixed symbols or badges. Hence the more external features of their life and behavior are likely to be imitated by classes immediately below them, who, in turn, are imitated by groups immediately below them in the social structure. This process gives to fashion a vertical descent. However, the elite class finds that it is no longer distinguishable, by reason of the imitation made by others, and hence is led to adopt new differentiating criteria, only to displace
these as they in turn are imitated.It is primarily this feature that makes fashion into a movement and which has led one writer to remark that a fashion, once launched, moves to its doom.
As a movement, fashion show little resemblance to any of the other movements which we have considered.While it occurs spontaneously and moves along in a characteristic cycle, it in volves little in the way of crowd behavior and it is not dependent upon the discussion process and the resulting public opinion. It does not depend upon the mechanisms of which we have spoken. The participants are not recruited through agitation. No morale is built up among them. Nor does the fashion movement have, or required, an ideology. Further, since it does not have a leader- ship imparting conscious direction to the movement, it does not build up a set of tactics. People take part in the fashion movement voluntarily and in response to the interesting and powerful kind of control which fashion imposes on them.

It is known from the first paragraph that______

A.fashion operates in every society

B.fashion can be found only in a few fields of group life

C.fashion originates in a class society

D.people like to keep up with fashion in a primitive society
